Avoid touching the UV lamps and the print block. UV Radiation The UV lamps used in the printer emit dangerous radiation. ¾ If the UV lamps remain on when the printer cover is open, do not stare directly at the UV light. Shut down the printer and call your Objet service provider. Printer Maintenance ¾ Service operations should be performed only by qualified personnel who have been instructed in relevant safety precautions. ¾ Notify co‐workers and those who have access to the Objet system before beginning non‐routine and hazardous work. Report any potential dangers and safety-related accidents to your safety officer or to other appropriate authorities. 2–4 DOC-07000 Rev. A Objet500 - Connex 3 User Guide Model and Support Materials Model and support materials are made of chemical substances. Although precautions must be taken when handling these materials directly, all model and support materials used by the Objet system are handled in sealed cartridges. Normally, operators of the printer should never be directly exposed to hazardous materials. In the unlikely event of a leak or spill, follow the instructions that are included with the printing‐material cartridge used. ¾ Store cartridges of model and support materials indoors, in a dry area with adequate ventilation, between 16‐27 degrees Celsius (60‐81 degrees Fahrenheit). Never expose them to flames, heat, sparks, or direct sunlight. ¾ Keep model and support materials away from areas where food and drink are stored, prepared and consumed. ¾ Uncured printing material is considered a hazardous substance, requiring certain precautions when directly handling it. To prevent skin irritation, wear neoprene or nitrile gloves. If there is any chance that model and support materials might splash into the eyes, wear safety goggles. Prolonged direct contact with printing materials can cause an allergic reaction. ¾ When handling UV‐cured models that may not be completely cured on the surface, common latex gloves are adequate. ¾ To prevent respiratory irritation, ventilate areas where model and support materials are used. The ventilation system should totally replace the air at least 20 times per hour. ¾ Clean up model‐material and support‐material spills with disposable towels or other absorbent, non‐reusable material, such as sawdust or activated charcoal. Rinse the spill area with denatured or isopropyl alcohol (IPA), followed by soap and water. Dispose of the absorbent material in accordance with local regulations. ¾ Do not wash contaminated clothing at home; clothing should be professionally laundered. ¾ Dispose of contaminated shoes, belts and other leather items in accordance with any applicable regulations. Absorbed printing material may re‐expose the user when these items are worn. DOC-07000 Rev. A 2–5 Safety First Aid for Working with Printing Materials In general, try to avoid direct contact with uncured printing material. If skin or eyes come into contact with it, wash the area immediately and thoroughly with water, and follow these first‐aid instructions. Contact with Skin If uncured printing material comes in contact with skin, wash the affected area immediately and thoroughly with soap and cool water, then remove contaminated clothing. Pay particular attention to flushing the hair, ears, nose and other parts of the body that are not easily cleaned. ¾ Use cool water to prevent skin pores from opening, so that the liquid material does not easily penetrate the skin. ¾ Do not use solvents to clean skin. ¾ If large areas of skin have been exposed, or if prolonged contact results in blisters, seek medical attention. In any case, if irritation persists, seek medical attention. ¾ Avoid the accidental transfer of printing material from the hands to other areas of the body, especially to the eyes. ¾ If protective cream was used, do not reapply it until the skin has been completely cleansed. Contact with Eyes If uncured printing material comes in contact with the eyes, flush immediately with large amounts of water for 15 minutes and seek medical attention. ¾ Avoid sunlight, fluorescent light, and other sources of ultraviolet radiation. The wearing of contact lenses when handling liquid printing materials is not recommended. If the liquid splashes into the eyes when contact lenses are worn, immediately remove the lenses and flush the eyes with water. ¾ Clean and disinfect the contaminated lenses. ¾ Do not wear contact lenses until eye irritation disappears. Ingestion If printing material is swallowed, refer to the instructions included with the cartridge. Seek medical attention immediately. Inhalation Vapors from printing materials can be irritating to the respiratory system. If respiratory irritation occurs, expose the victim to fresh air immediately. ¾ If the victim has stopped breathing, perform artificial respiration or cardiopulmonary resuscitation. ¾ Seek medical attention immediately. ¾ Keep the patient warm but not hot. ¾ Never feed anything by mouth to an unconscious person. ¾ Oxygen should be administered by authorized personnel only. 2–6 DOC-07000 Rev. A Objet500 - Connex 3 User Guide Waste Disposal Fully cured printed models can be disposed of as ordinary office trash. However, special care is required when handling printer waste. ¾ When removing the waste container from the Objet printer, wear neoprene or nitrile gloves. ¾ To prevent liquid waste from splashing into the eyes, wear safety goggles. ¾ Liquid waste from the Objet printer is classified as hazardous industrial waste. Therefore, printing‐material waste must be packaged and disposed of in a manner that prevents human contact with it and contamination of water sources. ¾ Empty model‐material and support‐material cartridges contain residue of their contents. Some leakage of this residue may occur through the broken cartridge seal. Therefore, handle and store empty cartridges with care. ¾ Do not attempt to reuse empty cartridges, and do not puncture them. ¾ Dispose of used cartridges and waste containers in accordance with local regulations. ¾ Discard contaminated clothing, shoes, empty containers, etc., in accordance with any applicable regulations.

A 3–1 Introducing the Objet 3-D Printing System Welcome to Connex The advanced capabilities of the Objet 3‐D printing system are made possible by PolyJet Matrix™ technology, specially developed by Objet for printing models simultaneously with different model materials. For the first time, you can achieve the following results when printing 3‐D models: • You can prepare models for printing with designated model materials and then print them—using two or three basic model materials loaded in the printer, or combinations of these materials (digital materials). • Parts of the same model can be made—simultaneously—from different materials. • Models made from digital materials can have unique physical properties, depending on the materials used. • You can print objects that have a “coating” made from a different material than the main part of the object. In addition, because Objet printers can be loaded with two different materials, and can print simultaneously with combinations of them, you can streamline and economize the process of producing models: • You can print models made from different (single) materials on the same build tray (“mixed tray”), in the same print job. This eliminates the time‐consuming need and expense of loading another material, flushing the system, and sending a separate job to be printed. • You can quickly alternate printing jobs with any of the model materials loaded—or with material combinations—again, without the need and expense of replacing materials. The Objet system also enables you to split models into component parts (“shells”) so you can isolate, manipulate and print parts of a model. However, you have ultimate control when separating models into shells by preparing stl files with your CAD software. Then, with Objet software, you can assign model materials and other characteristics to the shells. Figure 3-1: The 3-D Printer 3–2 DOC-07000 Rev. A Objet500 - Connex 3 User Guide Work Configurations The 3‐D printing system can be set up as a single‐station system or as a multi‐station system. When connected to a local computer network, the system can serve multiple users. In such configurations, each user workstation (client) prepares files with Objet Studio software for production. A server (host), typically next to the 3‐D printer, acts as a job manager that sends production jobs to the printer for production. Figure 3‐2 shows the printer set up in a multi‐client configuration. Client workstations Objet server KVM switch Printer workstation Objet printer Figure 3-2: Multi-client network configuration When installing the Objet software, you choose whether to install it as a client station or as a master station (server or standalone station). The Objet software arranges the jobs it receives according to their priorities, model‐material type, and other factors. In multi‐workstation configurations, the operator of the server—typically the production administrator—has total control over the jobs sent to the 3‐D printer, and can prioritize and delete jobs, review job history and reprint a job, and so on. DOC-07000 Rev. A 3–3 Introducing the Objet 3-D Printing System Source Files Objet 3‐D printing systems produce three‐dimensional models designed with most 3‐D CAD tools and with other job‐specific 3‐D applications. Objet systems accept: • STL Files • SLC Files Objet systems feature the capability of producing both types of model files simultaneously. STL Files STL is short for Standard Triangulation Language. This language views any object as a collection of surfaces, and describes each surface of the object as a collection of triangles. For example, a square can be described as two triangles; a cube (six squares) as 12 triangles. Curved surfaces need more triangles to describe them. The higher the tolerance (for smooth surfaces), the more triangles are needed. The result is that high‐quality object descriptions mean very heavy files. Most CAD software can export STL files. The Objet system utilizes these files for building models (rapid prototyping), and also for directly making molds for mass‐producing items. STL files are ASCII (text) files. The content of each file begins with “solid” and ends with “end‐solid” (both lower case). Between these keywords is a list of the triangles that describes the faces of the solid model. Each triangle defines a single normal vector directed away from the solid’s surface, followed by its X‐Y‐Z coordinates. These are expressed as Cartesian coordinates and are floating‐point values. The coordinates of all triangles should be positive and should fall within the volume of the model. SLC Files SLC is short for Stereo‐Lithography Contour. SLC files describe two‐ dimensional contours of the three‐dimensional models. These contour lines are polylines. SLC files are ASCII (text) files that save models as a series of slices. This means that models based on SLC files cannot be orientated; only their scale (size) and position on the build tray can be controlled. For this reason, the model’s orientation must be suitable for production before it is saved as an SLC file. Because of the nature of SLC files, the appearance of models in Objet Studio may be different than the solid‐object images displayed from STL files. Printing Materials Objet printers produce models by jetting thin layers of printing materials on the build tray, until the complete model is formed. Two types of material are used in this process: • Model material—which makes up the finished model • Support material—which fills gaps and spaces in the model during printing, and is removed after printing 3–4 DOC-07000 Rev. A Objet500 - Connex 3 User Guide Storage Materials used for printing models with Objet printers are made of resins, which are composed of reactive monomers and oligomers. Although printing materials are supplied in sealed, UV‐proof cartridges, care must be taken when storing and handling them. Follow these guidelines to protect operators and the environment, and to ensure optimum results. • To ensure product stability, do not allow these materials to come into contact with metal. Plastics made from monomer‐soluble substances (such as polystyrene or polyvinyl chloride) are not suitable for storing Objet printing materials. • When not in use, keep material cartridges tightly sealed to prevent contamination, the effects of exposure to UV radiation, and accidental spillage. • Store material cartridges indoors, in a dry area with adequate ventilation, between 16–27 degrees Celsius (60–81 degrees Fahrenheit). If exposed to heat or flames, cartridges may burst or ignite. • Signs of premature polymerization in material cartridges may include bulging, leaking, the emission of heat, and unusual odor. Exposure to heat can cause resin to gel in the cartridge. • Make sure that material cartridges are stored in accordance with all local regulations and other applicable requirements. Shelf Life Materials used for producing models have a limited shelf life. The expiry date on the label is valid when properly stored in an undamaged, unopened cartridge. Always rotate your stock, so that the cartridge with the earliest date is used first. Exposure to Light If printing materials are not in their sealed cartridges, make sure to shield them from sunlight and other sources of UV radiation, such as fluorescent and mercury‐vapor lights. Exposure to UV radiation causes an increase in viscosity and, eventually, solidification. Safety Considerations Before being cured, resins are hazardous materials. To prevent possible health hazards, follow these precautions regarding printing materials: • • • • Do not expose to flames, heat or sparks. Prevent contact with skin and eyes. Ventilate areas where they are handled. Keep them separate from food and drink. Cured plastic parts, however, are safe. They can be handled and stored without precautions. You can find more safety information about resins in “Safety Guidelines” on page 2-4, and “First Aid for Working with Printing Materials” on page 2-6. Disposal DOC-07000 Rev. A Dispose of cartridges of Objet model and support material in accordance with all applicable laws and regulations. If necessary, the cartridges can be disassembled for recycling. 3–5 Introducing the Objet 3-D Printing System Work Environment Extreme heat and humidity conditions can adversely affect the operation of the Objet 3‐D printer. Therefore, it is recommended that you use ventilation or air‐conditioning systems, if necessary, to keep the work area within the following ranges: • 18°–° C (64°–° F) • 30%–70% relative humidity 3–6 DOC-07000 Rev.

A 3–7 Introducing the Objet 3-D Printing System Preparing Files for Use with Objet 3-D Printing Systems Before using files with Objet 3‐D printing systems, you must convert them in your CAD program to either STL files or SLC files. (For an explanation of these file formats, see “Source Files” on page 3‐4.) After converting the model files, it is recommended that you check them for defects in an STL‐repair application (such as Magics, by Materialise) before opening them in Objet Studio and producing the model. Converting CAD Files to STL Format This procedure may vary slightly, depending on the CAD software used, but the following instructions generally apply. To convert a file to STL format (in a CAD program): 1. From the File menu, select Save As. 2. In the Save As dialog box, open the Save As Type pull‐down menu and select *.STL. 3. Click Options and set the following parameters: • Total Quality—approximately 0.1 mm (deviation tolerance / linear‐ dimension tolerance) • Detail Quality—approximately 4° (angle tolerance) Note: Lowering these values produces more accurate models, but results in larger files and longer loading and processing times. For this reason, it is generally not recommended that you use lower values. 4. In the file format option, choose binary or ASCII. (Both binary and ASCII formats can be used in Objet Studio. However, binary files are smaller, so this option is recommended.) 5. Click OK or Save. Converting Files to SLC Format 3–8 When converting files to SLC format, it is recommended that you set a layer thickness of 15 microns (0.015 mm). Since SLC files cannot be orientated in Objet Studio, it is important that models are properly orientated before being saved as SLC files. Considerations for suitable model orientation are explained in “Model Orientation” on page 5‐32. DOC-07000 Rev. A Objet500 - Connex 3 User Guide Objet Studio Software Objet Studio software for the Objet 3‐D printing system consists of two main screens: • Tray Settings / Model Settings • Job Manager Tray Settings / Model Settings In the Tray Settings and Model Settings screens, you prepare source files for production in Objet 3‐D printers. Objet Studio offers you a wide variety of file‐preparation options, but always consists of the following basic procedure: 1. Inserting one or more objects on the build tray 2. Positioning the object(s) on the tray 3. Configuring object and tray parameters 4. Saving the tray configuration as an objtf (Objet Tray Format) file 5. Sending the objtf file to the Objet 3‐D printer for production Using Objet Studio to perform these tasks is described in detail in chapter 5, “Using Objet Studio.” Job Manager The Job Manager screen is different for client workstations and for the computer connected directly to the Objet 3‐D printer. • In Objet Studio installed on the directly‐connected computer (server), the Job Manager screen displays the queue and status for all jobs sent to the 3‐D printer by the server itself and by all client computers on the network. All jobs displayed can be edited and manipulated. • In Objet Studio installed on client computers, the Job Manager screen displays the queue and status only for jobs sent to a 3‐D printer server from that computer. Only these jobs can be edited and manipulated from the client computer. Client computers can be connected, via the local network, to different Objet 3-D printers, but only to one at a time. The Job Manager screen displays the status of the 3-D printer to which the client is currently connected. DOC-07000 Rev. A 3–9 Introducing the Objet 3-D Printing System 3–10 DOC-07000 Rev.

Alternatively, you can fix its position at the left of the application window, and even hide it. 5–6 DOC-07000 Rev. A Objet500 - Connex 3 User Guide Preparing Models for Production Model preparation involves the following basic steps: 1. Place objects or assemblies on the build tray. 2. If necessary, manipulate the object’s orientation and position. 3. Select the materials and model finish. Just as Objet printers can produce different models on the build tray using different materials, you can produce components of a model with different materials. To do this, each part of the model must be a separate stl file. If the model’s component parts were not saved in the CAD software as separate stl files, you can use Objet Studio to separate the model into component parts. (This is described in “Splitting Objects into Components” on page 16 and in “Dividing Objects” on page 58.) OBJDF Files: Overview An objdf file describes both the geometry of a single object and the materials, and finish required to print it. The objdf file can represent an object that is a single stl file, or an object assembled from component stl files. Objet Studio enables you to split an stl file representing a complex object into an assembly of component stl files, and save the assembly as an objdf file. Each part (stl file) described by the objdf file can have its own model‐ material characteristic, so that the Objet printer produces the component parts from specific materials. Another use for objdf files is for saving a group of separate objects on the build tray as one unit, together with their relative positions and materials. This is especially useful for producing models in the future with the same materials. In fact, when you save objdf files, you specify materials for printing models without regard to the material cartridges loaded in the printer. The same object can later be placed on build trays for printing. Each time you send a build tray to the printer, you decide whether to allow printing with substitute materials or only with the materials specified. The Connex version of Objet Studio enables you to display, manipulate and print component parts of a model assembly that was saved as an objdf file, since each component is a separate stl file. This can be useful for printing only specific parts of a model. Model Files To produce models, you open one or more model files in Objet Studio and position objects on the build tray. You can place objects on the build tray in several ways: • by inserting individual stl or slc files (or an assembly of stl files). • by inserting an objdf file (an assembly). • by pasting objects that you copied to the Windows clipboard. DOC-07000 Rev. A 5–7 Using Objet Studio Placing Objects on the Build Tray To place an object on the build tray using stl, slc or files: 1. Open the Insert dialog box— • From the Object menu, select Insert. or— • On the Arrange Tray ribbon, click . or— • Right‐click on the build tray, and select Insert from the context menu. The Insert dialog box appears. 2. In the Look in field, display the appropriate folder. 3. In the Files of type field, select the file types to display (stl, slc, ). 4. Select the desired file, and make sure that it appears in the File name field. If the Preview check box is selected, the object is displayed in the dialog box. Note: You can open several stl files at once, to place several models on the build tray. If you select multiple stl files that make up an assembly, you can select all or some of the parts. To print the entire model, select all of an assembly’s component stl files, and select the Assembly check box. This positions the parts as a complete, integrated model instead of as independent parts. The effects of selecting the Assembly check box—in both the model tree and the build tray display—are shown in the following figures. 5–8 DOC-07000 Rev. A Objet500 - Connex 3 User Guide Figure 5-7: Assembly check box selected—stl files are placed as an assembly Figure 5-8: Assembly check box not selected—stl files are placed as parts The Model Settings ribbon is displayed when objects are placed on the build tray. 5. Select any of the following options, as required: • Units—Millimeters or inches for the object’s units of measure. The 3‐D file contains the objectʹs proportions, but not its units of measure. Therefore, make sure to correctly select either millimeters or inches when inserting an object. Otherwise, the size of the object on the build tray will be either much too large or much too small. To change the measurement units of objects already placed on the tray, see “Measurement Units” on page 36. • Number of copies—How many copies of this object to place on the build tray. • Orient Automatically—Automatically orient objects on the build tray for efficient model building. • Assembly—Mark this check box if you selected multiple stl files that are part of an assembly. DOC-07000 Rev. A 5–9 Using Objet Studio Note: The Extents values displayed in the Insert dialog box’s Coordinates field, represent the maximum dimensions of the object on each axis. These dimensions correspond to the virtual “bounding box” surrounding the object see figure 5-49 on page 36). 6. Click Insert. Objet Studio places the object on the build tray, and in the model tree. Model Tree pane Model Toolbar The Model Settings ribbon is displayed when objects are placed on the build tray. If the object is over a certain size, the Loading Placed Elements dialog box may appear.

A Objet500 - Connex 3 User Guide Opening files Before placing files on the build tray, Objet Studio must extract the component stl files together with information about their orientation and materials. To do this, Objet Studio creates a folder with the same name as the file, in the same location. Figure 5-9: Insert dialog box ( file) DOC-07000 Rev. A 5–11 Using Objet Studio Opening Objet Tray Files You can open trays that were saved as objtf files, for example, a tray you saved while preparing it for printing, and now you want to continue preparing it. To place an object saved as an Objet Tray File (objtf) file on the build tray: 1. From the File group, click . or— From the Objet Studio Commands, select Open. The Open dialog box is displayed. 2. Select the desired file, and make sure that it appears in the File name field. If the Preview check box is selected, the object is displayed. 3. Click Open. Objet Studio opens the tray file. 5–12 DOC-07000 Rev. A Objet500 - Connex 3 User Guide Stl file loading preference If there are identically named stl files in more than one location, you need to ensure that the correct component stl files are linked to the objtf file. For example, if there are identically named stl files on one drive and on a flash drive (this can occur if you copy the original files to a working folder), you can set the default location from which files are loaded.

Right-click model menu If you right‐click on an object, a pop‐up context menu is displayed from which you can also select the model finish, change its position and scale, and set the Grid Style and Hollow options. You can also create a Quick Access toolbar with your most commonly used icons grouped together. See “Building a Quick Access Toolbar” on page 89. 5–14 DOC-07000 Rev. A Objet500 - Connex 3 User Guide Copying and Pasting Objects If you need to duplicate objects on the build tray, you can, of course, insert the same object from its file more than once. An easier way, however, is to copy and paste the object. You can copy objects from the build tray or the model tree—individual or multiple parts or assemblies. The objects copied remain in the Windows clipboard until you paste them onto the build tray. You can also copy objects from one tray and paste them onto another, in the same way as you copy text from one document and paste it into another one. However, Objet Studio allows only one tray to be open at a time. For each build tray you need to work with (at the same time), you must open a separate Objet Studio window, by running the application again (from the Windows Start menu). Having multiple Objet Studio windows open can be convenient when you need to manipulate or configure objects before inserting them in your production build tray. For example, if you need to change the model material of an object (saved as an objdf file) to match the model material already used in the production build tray, you must do so before inserting the object—on another tray. Copying and pasting also allows you to utilize objects already configured on previously-used build trays for newer projects. You perform the Copy and Paste commands as in other Windows applications: • from the right‐click context menu. • by using keyboard shortcuts (Ctrl+C and Ctrl+V, respectively). The Paste Special command (from the object’s right‐click context menu) enables you to place duplicate objects even more efficiently: • You can specify the number of duplicates to place on the build tray at once. • You can set the distance, on each axis, between the duplicate objects. • You can manipulate mirror images of the original object, and flip them on selected axes. Figure 5-11: Paste Special dialog box DOC-07000 Rev. A 5–15 Using Objet Studio Selecting Objects To manipulate an object on the build tray or assign characteristics to it (model material, building style etc.), you must first select the object. You select an object by clicking it, either on the tray or in the model tree. Its image on the build tray changes color (to light blue, by default) and its name is highlighted in the model tree. You can select multiple objects by drawing a box around them with the mouse cursor, or by pressing the Ctrl or Shift keys while clicking additional objects. Alternatively, select or de‐select objects using the following Edit menu commands: • Select All • Invert Selection • Undo Select object Sometimes, you need to select individual elements of an assembly. Other times, you need to select the entire assembly. The Selection icon displayed on the ribbon determines what will be selected when you click on the model: or To change the selection action: 1. On the Arrange Tray or Model Settings ribbon— a. Click the Selection icon: or b. On the flyout toolbar, click the appropriate icon: Select Element Select Group Figure 5-12: Selection flyout toolbar Splitting Objects into Components 5–16 You can convert a complex object to an assembly of component parts. To do so, you split the stl file that represents the object into a group of separate stl files, each one representing a component. (This is referred to in the Objet Studio interface as separating the object into shells.) You can then assign a model material to each stl file, and you can save the newly‐created assembly as an objdf file. DOC-07000 Rev. A Objet500 - Connex 3 User Guide To split an object into an assembly of component parts: 1. If the object is not displayed, place it on the build tray by inserting its stl file (see “Placing Objects on the Build Tray” on page 8). The object appears—on the build tray and in the model tree pane—as a single part. It is assigned, by default, the “primary” model material. (If Objet Studio is configured with a secondary material, you can assign it—or a digital material—to the entire object. This is explained in “Model‐Material Settings” on page 18.) Figure 5-13: Object placed on the build tray from a single stl file Note: There is no need to resize or arrange the object on the build tray at this time. 2. With the object selected: • From the Object menu, select Separate into Shells. or— • On the ribbon, click A dialog box opens in which you can specify where to save the component stl files. (By default, Objet Studio offers to save the new files in a folder in the same location as the original stl file.) Figure 5-14: Folder selection for saving stl files after splitting into shells 3. Click OK. DOC-07000 Rev. A 5–17 Using Objet Studio Objet Studio splits the object into an assembly of component parts, each a separate stl file (“shell”). The object appears—on the build tray and in the model tree—as an assembly of parts (“shells”). You can assign each part a different model material (This is explained in “Model‐Material Settings” on page 18). Figure 5-15: Object after being converted to an assembly of component parts Model-Material Settings Before placing objects on the build tray in Objet Studio, you should pay attention to the material selection settings on the Arrange Tray ribbon. Figure 5-16: Material selection settings • By default, the material selection settings on the ribbon correspond to the three model cartridges loaded in the printer. • The materials displayed are basic model materials. These materials can later be combined to create digital materials (see “Digital Materials” on page 20). • The material displayed on the top (VeroWhite, in the figure above) is considered the primary model material (“Model‐1”). It is assigned to objects that do not have a material assignment when you place them on the build tray. For example, since stl files do not contain information about the model material, Objet Studio assigns the primary model material to them. Also, if you try to insert objdf files whose assigned materials are not recognized by your version of Objet Studio, you can insert the file by substituting the primary model material for the missing materials. • Select Single Material if you want to print using only one material—all of the material drop‐down menus contain the same material. If you decide to print with multiple materials, the material in the top drop‐ down menu remains assigned to the object until you select another material. • If you insert an objdf file into an empty build tray, and the model‐ material assignment does not match the settings on the Arrange Tray ribbon, these settings are changed automatically. However, if there is an 5–18 DOC-07000 Rev. A Objet500 - Connex 3 User Guide object already on the build tray whose materials do not match the material assignment in the objdf file, you cannot place the new object on the tray. To print this object, you have the following options: Instead of printing it on the same build tray, print the new object as a separate job. Change the materials assigned to objects on the build tray to match those assigned to the new object (see “Changing the Model Material” and “Assigning a Model Material to Objects,” below). Change the materials assigned to the new object before inserting it, so there is no conflict with the settings on the Tray Settings ribbon. To change the materials assigned to an object before inserting it: 1. Open another Objet Studio window, by running the application from the Windows Start menu. 2. Insert the new object (objdf file) into the empty build tray. 3. Change the material selection settings on the Tray Settings ribbon to those used on the other build tray. 4.

Select Matte or Glossy in one of the following places: • Model Settings ribbon, Options group • Model Toolbar • right‐click context menu (when selecting the model) You can configure Objet Studio to distinguish between objects’ surface finish on the build tray by color. To configure how Objet Studio displays objects, see “Setting Object Colors” on page 48. DOC-07000 Rev. A 5–21 Using Objet Studio Positioning Objects on the Build Tray To produce models efficiently and with the required finish, it is important to carefully position objects on the build tray. Objet Studio supports the automatic positioning of objects. However, you should check to make sure that the objects are orientated logically for your needs, according to the considerations explained in “Model Orientation” on page 5‐32. Two things that affect the positioning of objects on the build tray are orientation and placement. You can let Objet Studio determine the optimum orientation and position, or you can control them. Automatic Orientation By default, Objet Studio automatically orients objects, when placed on the build tray, for the shortest printing time. (You can later change the orientation manually.) However, you can cancel automatic orientation when placing an object on the build tray. To place an object on the build tray without automatic orientation: ¾ In the Insert dialog box, make sure Orient Automatically is not selected. 5–22 DOC-07000 Rev. A Objet500 - Connex 3 User Guide You can change the default setting, so that automatic orientation is not applied unless you select the Orient Automatically check box each time you place an object on the build tray. To do this, see “Default Settings” on page 70. DOC-07000 Rev. A 5–23 Using Objet Studio Automatic Placement After placing several objects on the build tray, you can let Objet Studio arrange them on the tray for printing. This ensures that the objects are positioned properly, and that they will be printed in the shortest time and with a minimum of material. To automatically arrange objects on the build tray: ¾ On the Tray Settings ribbon, click . or— From the Tools menu, select Automatic Placement. The effects of automatic positioning are shown in the figures below. Figure 5-20: objects are properly arranged Tray before Figure 5-21: arrangement when applying automatic placement Tray • For best results arrange the tray with Automatic Placement, on the Tray Settings ribbon, even if you inserted the objects with the Orient Automatically option. • The physical characteristics of each type of model material you use can affect the positioning of objects on the build tray. Therefore, select the material before running Automatic Placement. 5–24 DOC-07000 Rev. A Objet500 - Connex 3 User Guide Model Orientation The orientation of models on the build tray affects how quickly and efficiently they will be produced by the 3‐D printer, where and how much support material is used, and whether or not model parts will have a glossy finish. Therefore, you should consider a variety of factors when deciding how to place models on the tray, using the following positioning rules. X-Y-Z Rule This rule considers a modelʹs outer dimensions. ¾ Since the print heads move back and forth along the X‐axis, the printing time along this axis is relatively short, compared to printing time along the Y‐axis and Z‐axis. From this point of view, it is advisable to place the objectʹs largest dimension along the X‐axis. ¾ Any surfaces that come into contact with support materials become matte. ¾ Since models are built up, on the Z‐axis, in 30‐micron layers, it is very time‐consuming to print a tall object. From this point of view, it is advisable to place the objectʹs smallest dimension along the Z‐axis. ¾ Since the print heads measure about 2 inches (5 centimeters) on the Y‐ axis, models measuring less than this (on the Y‐axis) are printed in one pass. From this point of view, it is advisable to place the objectʹs intermediate dimension along the Y‐axis. Tall-Left Rule This rule considers models where, after being orientated on the build tray according to other considerations, one side is taller than the other. ¾ Since the print heads move along the X‐axis from left to right, taller sections on the right require the print heads to scan unnecessarily from the left until reaching them. If, on the other hand, the taller sections are positioned on the left of the tray, the print heads only have to scan the model until printing these sections—once the lower parts have been completed. Therefore, you should position the taller side of the model, when possible, on the left. Recess-Up Rule This rule considers models containing surface recesses. ¾ Recesses in the surface (like hollows, drill holes, etc.) should, when possible, be positioned face‐up. Fine-Surface Rule This rule considers models that have one side on which there are fine details (like the keypad side of a telephone). ¾ The side of the model containing fine details should, when possible, be positioned face‐up. This results in a smooth finish. Avoid Support-Material Rule This rule considers models that have large holes or hollows, open on at least one side (like a pipe or a container). ¾ It may be advantageous to print a model standing up, so support material does not fill the hollow, even though printing the model lying down would be much faster. DOC-07000 Rev. A 5–25 Using Objet Studio Manipulating Objects on the Build Tray Positioning Objects on the Z-Axis When you use the automatic positioning option to arrange objects on the build tray, the objects are positioned directly on the tray. If you do not insert objects with automatic positioning, they often appear either above or below the tray. In practice, the Objet system prints all models on the build tray on a onemillimeter bed of support material. The importance of positioning objects directly on the build tray with Objet Studio is to correctly display the objects on the screen. To position objects directly on the tray: 1. Select the object. 2. From the Object menu, select Lay On. To ensure that objects are always positioned directly on the tray: 1. From the Tools menu, select Options, and display the Settings tab. 2. In the Automatic Lay On (Gravity) section, select Always. Other Z-axis options (in the Automatic Lay On section): • When under the tray—The display of objects that are below the build tray is automatically changed so that the object is at tray level. • Never—The display of objects that are above or below the build tray is not changed. Valid Object Placement You can ensure that models do not overlap when you position them on the build tray, and that they do not extend beyond the tray. To ensure valid object placement: 1. From the Tools menu, select Constraints Settings. 5–26 DOC-07000 Rev. A Objet500 - Connex 3 User Guide 2. Select Dynamic check to identify: • • • • invalid object placement while placing objects—On Drop selected. invalid object placement after moving objects—While Drag selected. objects placed beyond the tray’s boundaries—Outside Tray selected. objects that overlap—Object Collision selected. Even if you do not use Dynamic Check when placing objects on the build tray, Objet Studio automatically checks if there is a problem with the positioning of objects on the tray before sending it to the printer. You can also manually check for problems after positioning objects. Note: Remember that Objet Studio calculates the space occupied by an object including the “bounding box” surrounding it (see figure 5-40 on page 44). DOC-07000 Rev.

Click Apply. DOC-07000 Rev. A 5–43 Using Objet Studio “Hollow”— Filling Models with Support Material Many objects placed on the tray from stl files are “solid.” This means that, when printed, the model will be completely filled with model material. Often, especially with large objects, this is unnecessary. Instead, the model can be filled with support material, which is less costly. It is also advisable to fill models with support material when preparing them for investment casting, since this material burns off more quickly during the process of making the cast. Objet Studio enables you to print objects on the tray with an outer shell of model material and a center filled with support material. This feature of Objet Studio is called “Hollow.” You can set the thickness of the shell— between 0.015 and 3.825 millimeters. To use the Hollow feature: 1. Select a model on the tray. or— • On the Model Toolbar, click . or— • From the right‐click context menu, select Advanced Properties. The Advanced Properties dialog box opens. 2. Select Hollow. 3.

A Objet500 - Connex 3 User Guide Monitoring and Managing Print Jobs In the Job Manager screen of Objet Studio, you monitor and manage jobs sent to the printer. There are a few differences between Objet Studio on client workstations and on the computer connected directly to the 3‐D printer—the server workstation. • Objet Studio installed on a client computer only displays the queue and status for jobs sent to the 3‐D printer server from that computer, and it allows the user to edit only these jobs. Note: If there are several Objet printers on the local network, client computers can connect to any of them, but only one at a time. • Objet Studio installed on the computer directly connected to a specific 3‐D printer (server), displays the queue and status for all jobs sent to that 3‐D printer by the server and by all client computers on the network. It also allows editing and manipulation of all jobs, and enables re‐sending previously‐printed jobs to the printer. If Objet Studio is not connected to a printer (or printer server), you can prepare tray files for any Objet printer. Later, these files can be used by Objet Studio on the appropriate printer server. Job Manager Screen The Job Manager screen on the client and server workstations looks identical. The only difference is that options only relevant to the server workstation are disabled for client installations.

A 6–3 Operating & Maintaining the Objet500 - Connex 3 3D Printer Loading Model and Support Cartridges Objet500 ‐ Connex 3 printers use six cartridges of model material and two cartridges of support material, each weighing 3.6 kilograms when full. A graphical representation of the cartridges loaded and their current weight appears in the printer interface (see figure 6‐3). The materials cabinet uses RFID technology to automatically identify cartridges of printing material. For this purpose, an RFID module is built into the cabinet. Tampering with this module will render the printer inoperable and may void Objet warranties and service contracts. Important: If you need to replace the model material currently installed with another type, see “Changing the Model Material” on page 6‐11. Otherwise, make sure to replace the model cartridge with one containing the same type of material. To load model and support cartridges: 1. Open the door of the materials cabinet. 2. If you are replacing a cartridge, grasp its handle and pull the cartridge out, taking care not to twist or turn it. 3. Load model and support cartridges into their respective compartments. You should feel some resistance, as a needle pierces the cartridge. 4. Check the printer interface to make sure that the new cartridge is detected and that its weight is displayed (see figure 6‐3). 5. Close the materials cabinet. Tips about replacing cartridges: • You can replace material cartridges either before or during printing. • If printing stops for an extended time before you replace a material cartridge, the printer may go into Standby or Idle mode. If this happens, see “Resuming Production After Printing has Stopped” on page 9. • You can replace partially used cartridges to avoid the need for replacing them during printing. • You can load partially used cartridges, as long as they contain more than 100 grams of material. 6–4 DOC-07000 Rev. A Objet500 - Connex 3 User Guide Producing Models The Objet500 ‐ Connex 3 printer produces models by printing tray files prepared in the Objet Studio application and sent to the printer from there. For information about preparing model files for printing, see “Using Objet Studio” or Objet Studio Help. Before beginning to produce models, it is recommended that you check the current printing quality of the print heads by performing a pattern test (see “Pattern Test” on page 20). To prepare the printer for producing models: 1. Make sure that the build tray in the printer is empty and clean. If not, remove old material with the scraper, and clean the tray thoroughly with cleaning fluid. CAUTION: Use protective gloves when cleaning the build tray, and be careful of the sharp edges of the scraper blade. 2. Make sure that there is sufficient model and support material loaded, as indicated in the printer interface (see figure 6‐2). You may want to replace the cartridges of model and support material currently loaded in the printer to avoid the need for replacing them during printing. For installing material cartridges and replacing empty ones, see “Loading Model and Support Cartridges” on page 6‐4. For changing the type of model material currently loaded, see “Changing the Model Material” on page 11. 3. At the bottom of the printer interface, click the red button to switch the printer to online mode. The color of the button changes from red to green (see figure 6‐3). If there is a job in the Job Manager queue, it is sent to the printer. In the printer interface, the printer mode changes from Idle to Pre‐print, as the printer’s components prepare themselves for production: • The print block is heated. • The UV lamps are powered and they warm up. When printing begins, Objet Studio sends seven slices to the printer. This is the standard buffer between Objet Studio and the printer. As each slice is printed, another slice is sent to the printer. Depending on the size of the model(s) to be produced, printing can take between several hours to several days. As long as there is enough model and support material in the supply cartridges, printing proceeds automatically until the job is finished. During printing, the server computer must remain on and it must communicate with the Objet printer. Do not log-off Windows until printing is finished. DOC-07000 Rev.

The amount of material flushed depends on the flushing cycle chosen and if you are replacing one or more materials. The Material Replacement Wizard suggests the best slot locations for placing different material cartridges, based on materials in the system. This ensures minimum flushing of materials currently loaded. To replace the model material: 1. Start the Material Replacement Wizard from the Options menu. Figure 6-8: Starting the Material Replacement Wizard from the Options menu 2. In the opening screen, click Next DOC-07000 Rev. A 6–11 Operating & Maintaining the Objet500 - Connex 3 3D Printer 3. If the printer cover is not closed, a screen appears instructing you to close the cover. Confirm that it is closed and click Next. Figure 6-9: Material Replacement Options In the Material Replacement Options screen, you select the settings that determine how the wizard replaces material currently in the system with newly loaded material. 4. Choose whether you want to produce models in Single Material mode or in Digital Material (“multiple‐materials”) mode. • Single Material mode Four print heads are used to print, using one model material. This mode is required to produce build trays with the High Quality setting, and to produce trays with the High Speed setting using only one model material. • Digital Material mode Each of the model materials loaded is used in two of the print heads. If only one of the model materials is required for printing, models are produced using two print heads. This makes it unnecessary to replace the other model material. If model‐material substitution is allowed, the printer produces trays with the High Speed setting using a mixture of model materials (see “Model Material Substitution” on page 5‐112). 5. In the Required materials section of the wizard screen, select one or more replacement materials. 6. Select Both cartridges if you need to load two replacement cartridges. Loading one replacement cartridge (if sufficient) is more economical because it potentially requires less flushing of material currently in the system. 6–12 DOC-07000 Rev. A Objet500 - Connex 3 User Guide 7. In the Flushing cycle section of the wizard screen, choose how thoroughly you want to flush out material currently in the system. • Economy. This cycle can be used when replacing a light‐colored model material with a darker material (such as TangoBlack™ or VeroBlack™), or if the exact color of the printed models is unimportant. The wizard flushes the system with the minimum amount of material needed to ensure that models have the mechanical properties of the new material. • Full. Use this cycle when the printed models must have the exact color of the new material. The wizard thoroughly flushes the feed tubes and print heads needed for printing, based on your selections in the previous screens.

Too many missing lines, especially if they are in the same area, indicates that the quality of printing when producing models will be poor. If this is the case, see “Improving Print Quality,” below. Note: Acceptable model quality is subjective, and depends on the type and scale (size) of the models produced. As a rule, however, more than 10 missing lines in one area of a column is considered unacceptable. Improving Print Quality If you suspect that print quality is poor, perform the pattern test (see “Pattern Test” on page 6‐20). If the results are poor, use the following procedure to improve print quality. If the results of the last pattern test are poor: 1.

From right to left, the columns represent heads M1, M2, M3, respectively. (There is no column for head M0 because its alignment is used as a reference for aligning all other heads.) • The four columns of lines on the left were printed by the heads used for applying support material. The columns represent heads S3, S2, S1 and S0, respectively. 9. For each column of lines, use a magnifying glass or loupe to inspect pairs of consecutive rows printed on the transparency to see where the vertical lines align. Alignment-line numbering, left-to-right Row pairs Figure 6-40: Comparing rows of alignment lines Note: It does not matter which pair of lines you inspect, since they were all printed by the same head. Choose a pair of clearly printed lines for the inspection. (Since some nozzles may not print clearly, you may have to inspect several pairs of lines to properly view the alignment.) Optimum head alignment is shown when the fourth lines in the upper and lower rows are aligned, as in figure 6‐39. In the example shown, no change to the head alignment is necessary.

Figure 6-43: Final Head Alignment Wizard screen Calibrating Print Heads The condition of the print heads directly affects the quality of printed models. To maintain optimum printing, you should routinely test the print heads, and calibrate them to the best working configuration possible. You do this by running the Head Optimization Wizard. If, during the optimization process, the wizard determines that a print head is faulty—or that it is negatively affecting layer uniformity with the current head configuration—the wizard instructs you to replace it. If this happens, you can continue the wizard (to replace the print head) or abort the wizard (to replace the head at another time). Run the Head Optimization Wizard whenever the condition of print heads is negatively affecting the quality of printed models, or if you suspect that there is a problem with one or more of the print heads. Note: Allow at least three hours for performing this procedure (not including time required for replacing faulty print heads). To accurately test and calibrate print heads, they must be clean.

A 6–45 Operating & Maintaining the Objet500 - Connex 3 3D Printer Replacing the Waste Container The waste container contains partially cured polymeric material produced during normal operation and maintenance of the printer. For safety and environmental reasons, this material is kept in a special leak‐proof, disposable container. The container has a capacity of 10 kilograms of waste material—usually enough for several months of printer use. The printer software displays a warning message when there is 9 kilograms of material in the container, and stops the printing when the net weight reaches 9.5 kilograms. Above 9 kilograms, the software does not allow you to start a print job (or a printing activity) until you replace the waste container. You can monitor the weight of the waste container in the Maintenance screen of the printer interface. You can also visually inspect the level of waste in the container. (To access it, see page 6‐237.) To monitor the waste weight (and other indicators) in the printer: ¾ In the main printer interface screen, click the display toggle to view the printer indicators. Waste weight Display toggle button Figure 6-60: Printer interface, showing waste weight (red background indicates operator alert) The waste container consists of a plastic container inside a cardboard box. You typically dispose of the entire waste container—including the box. Therefore, you must assemble a new box and insert a new plastic container before you can install it in the printer. Replacement boxes, plastic containers, and sealing caps are supplied in the Objet printer start-up kit and in the preventive-maintenance kit. 6–46 DOC-07000 Rev. A Objet500 - Connex 3 User Guide To prepare a new waste container: 1. Assemble the cardboard box, making sure to punch out the perforated sections. 2. Place a new plastic container into the box. Note: Do not close the box until you connect the waste drain tube from the printer (see below). To replace the waste container: Locate the door on the lower‐left side of the printer.Push in the upper‐ right corner of the door to release the latch and open the door. Figure 6-61: Accessing the waste container 3. Carefully slide out the waste container to remove it from the printer. Figure 6-62: Removing the waste container 4. Place the new waste container next to the full container. 5. Unscrew the cap securing the waste drain tube and connect it to the new container. 6. Close the full container with a sealing cap. 7. Close the new waste‐container box, using tape to hold it closed. 8. Position the waste container under the printer, on the load cells. • The container should be on the extreme right side of the compartment. • Make sure that the waste drain tube is not crimped and that it is not pinched by the container.

A Handling Printed Models Removing Models After Printing.............................................................. 2 Removing the Support Material................................................................ 2 Storing Models............................................................................................. 5 DOC-07000 Rev. A 7–1 Handling Printed Models Removing Models After Printing After printing models, you should allow them to cool as much as possible before handling them. If additional models do not have to be produced on the printer, it is best to let the printed models cool in the printer, with the cover closed, as long as possible. If the printer must be used to produce additional models as soon as possible: 1. Let the printed models cool on the build tray for at least 10 minutes. 2. Very carefully, remove the models from the tray with a scraper or spatula (supplied in the tool kit), taking care not to pry or bend the model. WARNING: Wear protective gloves when handling printed models before they are washed. 3. Place the models on a flat surface, and cover them with a cardboard box or paper hood. This allows the models to cool slowly and evenly. 4. Let the models cool for several hours. Removing the Support Material After printed models have cooled, the support material must be removed. This can be done by different methods, depending on the size of the model, how delicate it is, the amount and location of the support material, and other factors. Use the following methods as a guide, and adapt them (or a combination of them) for finishing the models you are handling. Removing Excess Support Material by Hand While wearing protective gloves, break away excess support material on the outside of the model. For delicate models, use a toothpick, pin or small brush after dipping the model in water. Removing Support Material with Water Pressure For most models, the most efficient way to remove support material is by using a high‐pressure water jet. One suitable system is the Balco WaterJet cleaning unit, shown in figure 7‐1 on page 7‐3. This device is marketed by Objet. 7–2 DOC-07000 Rev. A Objet500 - Connex 3 User Guide Figure 7-1: Balco WaterJet Cleaning Unit To clean a model using this device, you place it in the chamber, and you manipulate it and the jet using the built‐in, waterproof sleeves. A pump turns ordinary tap water into a high‐pressure jet, and a wiper keeps the window clear. Use caution when cleaning delicate models with high-pressure water systems. Removing Support Material with Caustic Soda Soak models in a 2‐percent solution of caustic soda (sodium hydroxide) to remove support material from difficult‐to‐reach areas and to give the model a smooth, clean finish. The amount of time you soak the model in the solution depends on how delicate it is and how much support material needs to be removed, but it is typically between half‐an‐hour and several hours. In any case, you should remove as much support material as possible before the caustic soda treatment, and rinse the model thoroughly (with a water jet) afterwards. WARNING: Caustic soda may cause chemical burns, scarring and blindness. Mixing it with water generates heat that could ignite other materials.Take adequate safety precautions; always use nitrile gloves when handling caustic soda and models soaked in it. DOC-07000 Rev. A 7–3 Handling Printed Models Post-Printing Treatment for Models Printed with Objet VeroClear Models made with Objet VeroClear have a slight yellow tint when removed from the printer. This is especially true for models printed with a glossy finish. The yellow tint fades naturally over time, but you can greatly accelerate this process by using a suitable photobleaching treatment. As a rule, best clarity is achieved when parts are printed with a matte finish, and treated as explained below. Photobleaching models involves exposing them to light. To achieve highly controlled and predictable results, a professional illumination chamber is recommended. However, adequate results may be obtained using ordinary desk lamps fitted with suitable fluorescent elements. Figure 7-2: PhotoBleaching Instructions Figure 7-3: Follow these instructions for photobleaching printed models. • The fluorescent lamps should be rated 45W, 6500K. • When using desk lamps, place the models in a container covered with aluminum foil. Use at least two lamps, more when treating models in a large container. • Arrange the models with enough space between them to allow light to reach all sides of each model. • Verify that the ambient temperature around the models is approximately 40ºC (104ºF). Higher temperatures may cause model distortion; lower temperatures may not produce satisfactory results. When using desk lamps, you can achieve the required temperature by positioning the lamps approximately 10 cm (4 in.) above the models. • Inspect the models after six hours of treatment. For parts with a matte finish, this should be enough. Polish and lacquer the parts. For parts with a glossy finish, continue the photobleaching treatment for up to 18 hours more. In Objet laboratories, there was a tint reduction of approximately 70% within six hours. After 24 hours, tint was reduced by approximately 90%. For more information about this treatment, see the application note “Objet VeroClear for Desktop Pro Printers” (DOC-24131). 7–4 DOC-07000 Rev. A Objet500 - Connex 3 User Guide Storing Models Models are cured as they are printed, making them safe and stable for a long time. However, proper storage conditions are necessary to prevent deforming. • Keep printed models at room temperature and in a low‐humidity environment. • Do not expose models to direct sunlight and other heat sources.
