DOC-06800 Rev. A 2–5Objet1000 - Connex 2 User GuideModel and SupportMaterialsModel and support materials are made of chemical substances. Althoughprecautions must be taken when handling these materials directly, allmodel and support materials used by the Objet system are handled insealed cartridges. Normally, operators of the printer should never bedirectly exposed to hazardous materials. In the unlikely event of a leak orspill, follow the instructions that are included with the printing materialcartridge used.Store cartridges of model and support materials indoors, in a dry areawith adequate ventilation, between 16 27 degrees Celsius (60 81degrees Fahrenheit). Never expose them to flames, heat, sparks, ordirect sunlight.Keep model and support materials away from areas where food anddrink are stored, prepared and consumed.Uncured printing material is considered a hazardous substance,requiring certain precautions when directly handling it. To prevent skinirritation, wear neoprene or nitrile gloves. If there is any chance thatmodel and support materials might splash into the eyes, wear safetygoggles. Prolonged direct contact with printing materials can cause anallergic reaction.When handling UV cured models that may not be completely cured onthe surface, common latex gloves are adequate.To prevent respiratory irritation, ventilate areas where model andsupport materials are used. The ventilation system should totallyreplace the air at least 20 times per hour.Clean up model material and support material spills with disposabletowels or other absorbent, non reusable material, such as sawdust oractivated charcoal. Rinse the spill area with denatured or isopropylalcohol (IPA), followed by soap and water. Dispose of the absorbentmaterial in accordance with local regulations.Do not wash contaminated clothing at home; clothing should beprofessionally laundered.Dispose of contaminated shoes, belts and other leather items inaccordance with any applicable regulations. Absorbed printingmaterial may re expose the user when these items are worn. D R A F T 16 June 2013
Safety2–6 DOC-06800 Rev. AFirst Aid for Working with Printing MaterialsIn general, try to avoid direct contact with uncured printing material. Ifskin or eyes come into contact with it, wash the area immediately andthoroughly with water, and follow these first aid instructions.Contact with SkinIf uncured printing material comes in contact with skin, wash the affectedarea immediately and thoroughly with soap and cool water, then removecontaminated clothing. Pay particular attention to flushing the hair, ears,nose and other parts of the body that are not easily cleaned.Use cool water to prevent skin pores from opening, so that the liquidmaterial does not easily penetrate the skin.Do not use solvents to clean skin.If large areas of skin have been exposed, or if prolonged contact resultsin blisters, seek medical attention. In any case, if irritation persists, seekmedical attention.Avoid the accidental transfer of printing material from the hands toother areas of the body, especially to the eyes.If protective cream was used, do not reapply it until the skin has beencompletely cleansed.Contact with EyesIf uncured printing material comes in contact with the eyes, flushimmediately with large amounts of water for 15 minutes and seek medicalattention.Avoid sunlight, fluorescent light, and other sources of ultravioletradiation.The wearing of contact lenses when handling liquid printing materials isnot recommended. If the liquid splashes into the eyes when contact lensesare worn, immediately remove the lenses and flush the eyes with water.Clean and disinfect the contaminated lenses.Do not wear contact lenses until eye irritation disappears.Ingestion If printing material is swallowed, refer to the instructions included with thecartridge. 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.If the victim has stopped breathing, perform artificial respiration orcardiopulmonary resuscitation.Seek medical attention immediately.Keep the patient warm but not hot.Never feed anything by mouth to an unconscious person.Oxygen should be administered by authorized personnel only.The Material Safety Data Sheet (MSDS) that accompanies printing materials contains important safety information. Keep this in an accessible place where these materials are used and stored. D R A F T 16 June 2013
DOC-06800 Rev. A 2–7Objet1000 - Connex 2 User GuideWaste Disposal Fully cured printed models can be disposed of as ordinary office trash.However, special care is required when handling printer waste.When removing the waste container from the Objet printer, wearneoprene or nitrile gloves.To prevent liquid waste from splashing into the eyes, wear safetygoggles.Liquid waste from the Objet printer is classified as hazardous industrialwaste. Therefore, printing material waste must be packaged anddisposed of in a manner that prevents human contact with it andcontamination of water sources.Empty model material and support material cartridges contain residueof their contents. Some leakage of this residue may occur through thebroken cartridge seal. Therefore, handle and store empty cartridgeswith care.Do not attempt to reuse empty cartridges, and do not puncture them.Dispose of used cartridges and waste containers in accordance withlocal regulations.Discard contaminated clothing, shoes, empty containers, etc., inaccordance with any applicable regulations.

Introducing the Objet 3D Printing System3–2 DOC-06800 Rev. AWelcome to ConnexThe advanced capabilities of the Objet 3 D printing system are madepossible by PolyJet Matrix technology, specially developed by Objet forprinting models simultaneously with different model materials. For thefirst time, you can achieve the following results when printing 3 D models:•You can prepare models for printing with designated model materialsand then print themusing two basic model materials loaded in theprinter, or combinations of these materials (digital materials).•Parts of the same model can be madesimultaneouslyfrom differentmaterials.•Models made from digital materials can have unique physicalproperties, depending on the materials used.•You can print objects that have a coating made from a differentmaterial than the main part of the object.In addition, because Objet printers can be loaded with two differentmaterials, and can print simultaneously with combinations of them, youcan streamline and economize the process of producing models:•You can print models made from different (single) materials on thesame build tray (mixed tray), in the same print job. This eliminatesthe 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 either of the modelmaterials loadedor with material combinationsagain, without theneed 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 bypreparing stl files with your CAD software. Then, with Objet software, youcan assign model materials and other characteristics to the shells.Figure 3-1: The 3D Printer D R A F T 16 June 2013

A server (host), typically next to the 3D printer, acts as a jobmanager that sends production jobs to the printer for production.Figure 3 2 shows the printer set up in a multi client configuration.Figure 3-2: Multi-client network configurationWhen installing the Objet software, you choose whether to install it as aclient 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 workstationconfigurations, the operator of the servertypically the productionadministratorhas total control over the jobs sent to the 3D printer, andcan prioritize and delete jobs, review job history and reprint a job, and soon.ClientworkstationsPrinter D R A F T 16 June 2013
Introducing the Objet 3D Printing System3–4 DOC-06800 Rev. ASource Files Objet 3D printing systems produce three dimensional models designedwith most 3D CAD tools and with other job specific 3D applications. Objetsystems accept:•STL Files•SLC FilesObjet systems feature the capability of producing both types of model filessimultaneously.STL Files STL is short for Standard Triangulation Language. This language views anyobject as a collection of surfaces, and describes each surface of the object asa collection of triangles.For example, a square can be described as two triangles; a cube (sixsquares) as 12 triangles. Curved surfaces need more triangles to describethem. The higher the tolerance (for smooth surfaces), the more triangles areneeded. The result is that high quality object descriptions mean very heavyfiles.Most CAD software can export STL files. The Objet system utilizes thesefiles for building models (rapid prototyping), and also for directly makingmolds for mass producing items.STL files can be ASCII (text) files or binary files. The content of the ASCIIfile begins with solid and ends with end solid (both lower case).Between these keywords is a list of the triangles that describes the faces ofthe solid model. Each triangle defines a single normal vector directed awayfrom the solids surface, followed by its X Y Z coordinates. These areexpressed as Cartesian coordinates and are floating point values. Thecoordinates of all triangles should be positive and should fall within thevolume of the model.SLC Files SLC is short for Stereo Lithography Contour. SLC files describe twodimensional contours of the three dimensional models. These contour linesare polylines.SLC files are ASCII (text) files that save models as a series of slices. Thismeans 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, themodels orientation must be suitable for production before it is saved as anSLC file. Because of the nature of SLC files, the appearance of models inObjet Studio may be different than the solid object images displayed fromSTL files. D R A F T 16 June 2013

Introducing the Objet 3D Printing System3–6 DOC-06800 Rev. APrinting MaterialsObjet printers produce models by jetting thin layers of printing materialson the build tray, until the complete model is formed. Two types of materialare used in this process:•Model materialwhich makes up the finished model•Support materialwhich fills gaps and spaces in the model duringprinting, and is removed after printingStorage Materials used for printing models with Objet printers are made of resins,which are composed of reactive monomers and oligomers. Althoughprinting materials are supplied in sealed, UV proof cartridges, care must betaken when storing and handling them. Follow these guidelines to protectoperators and the environment, and to ensure optimum results.•To ensure product stability, do not allow these materials to come intocontact with metal. Plastics made from monomer soluble substances(such as polystyrene or polyvinyl chloride) are not suitable for storingObjet printing materials.•When not in use, keep material cartridges tightly sealed to preventcontamination, the effects of exposure to UV radiation, and accidentalspillage.•Store material cartridges indoors, in a dry area with adequateventilation, 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 includebulging, leaking, the emission of heat, and unusual odor. Exposure toheat can cause resin to gel in the cartridge.•Make sure that material cartridges are stored in accordance with alllocal regulations and other applicable requirements.Shelf Life Materials used for producing models have a limited shelf life. The expirydate on the label is valid when properly stored in an undamaged,unopened cartridge. Always rotate your stock, so that the cartridge withthe earliest date is used first.Exposure to LightIf printing materials are not in their sealed cartridges, make sure to shieldthem from sunlight and other sources of UV radiation, such as fluorescentand mercury vapor lights. Exposure to UV radiation causes an increase inviscosity and, eventually, solidification.Safety ConsiderationsBefore being cured, resins are hazardous materials. To prevent possiblehealth 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 storedwithout 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.

Introducing the Objet 3D Printing System3–8 DOC-06800 Rev. APreparing Files for Use with Objet 3D Printing SystemsBefore using files with Objet 3D printing systems, you must convert themin your CAD program to either stl files or slc files. (For an explanation ofthese file formats, see Source Files on page 3 4.)After converting the model files, it is recommended that you check them fordefects 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 FormatThis 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 andselect *.STL.3. Click Options and set the following parameters:•Total Qualityapproximately 0.01 mm (deviation tolerance /linear dimension tolerance)•Detail Qualityapproximately 5° (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 andASCII formats can be used in Objet Studio. However, binary files aresmaller, so this option is recommended.)5. Click OK or Save.Converting Files to SLC FormatWhen converting files to SLC format, it is recommended that you set a layerthickness of 15 microns (0.015 mm). Since SLC files cannot be orientated inObjet Studio, it is important that models are properly orientated beforebeing saved as SLC files. Considerations for suitable model orientation areexplained in Model Orientation on page 5 29.For more information, search for “CAD to STL” on objet.com. D R A F T 16 June 2013

DOC-06800 Rev. A 5–9Objet1000 - Connex 2 User GuidePreparing Models for ProductionModel 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 usingdifferent materials, you can produce components of a model with differentmaterials. To do this, each part of the model must be a separate stl file. If themodels component parts were not saved in the CAD software as separatestl files, you can use Objet Studio to separate the model into componentparts. (This is described in Splitting Objects into Components on page 18and in Dividing Objects on page 54.)OBJDF Files: OverviewAn objdf file describes both the geometry of a single object and thematerials, and finish required to print it. The objdf file can represent anobject that is a single stl file, or an object assembled from component stlfiles.Objet Studio enables you to split an stl file representing a complex objectinto an assembly of component stl files, and save the assembly as an objdffile. Each part (stl file) described by the objdf file can have its own modelmaterial characteristic, so that the Objet printer produces the componentparts from specific materials.Another use for objdf files is for saving a group of separate objects on thebuild tray as one unit, together with their relative positions and materials.This is especially useful for producing models in the future with the samematerials. In fact, when you save objdf files, you specify materials forprinting models without regard to the material cartridges loaded in theprinter. The same object can later be placed on build trays for printing. Eachtime you send a build tray to the printer, you decide whether to allowprinting with substitute materials or only with the materials specified.The Connex version of Objet Studio enables you to display, manipulate andprint 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 printingonly specific parts of a model.Further explanations of files, and their features, appear throughout thischapter.Model Files To produce models, you open one or more model files in Objet Studio andposition objects on the build tray. You can place objects on the build tray inseveral 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.

Foreach build tray you need to work with (at the same time), you must open aseparate Objet Studio window, by running the application again (from theWindows Start menu).You perform the Copy and Paste commands as in other Windowsapplications:•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 atonce.•You can set the distance, on each axis, between the duplicate objects.•You can manipulate mirror images of the original object, and flip themon selected axes.Figure 5-18: Paste Special dialog boxHaving 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 use objects already configured on previously-used build trays for newer projects. D R A F T 16 June 2013

Using Objet Studio5–26 DOC-06800 Rev. APositioning Objects on the Build TrayTo produce models efficiently and with the required finish, it is importantto carefully position objects on the build tray. Objet Studio supports theautomatic positioning of objects. However, you should check to make surethat the objects are orientated logically for your needs, according to theconsiderations explained in Model Orientation on page 5 29.Two things that affect the positioning of objects on the build tray areorientation and placement. You can let Objet Studio determine the optimumorientation and position, or you can control them.Automatic OrientationBy default, Objet Studio automatically orients objects, when placed on thebuild tray, for the shortest printing time. (You can later change theorientation manually.) However, you can cancel automatic orientationwhen placing an object on the build tray.To place an object on the build tray without automatic orientation:In the Insert dialog box, make sure Orient Automatically is not selected.Figure 5-32: Orient Automatically option disabledYou can change the default setting, so that automatic orientation is notapplied unless you select the Orient Automatically check box each time you place an object on the build tray.

DOC-06800 Rev. A 5–29Objet1000 - Connex 2 User GuideModel OrientationThe orientation of models on the build tray affects how quickly andefficiently they will be produced by the 3D printer, where and how muchsupport material is used, and whether or not model parts will have a glossyfinish. Therefore, you should consider a variety of factors when decidinghow to place models on the tray, using the following positioning rules.X-Y-Z RuleThis rule considers a model s outer dimensions.Since the print heads move back and forth along the X axis, the printingtime along this axis is relatively short, compared to printing time alongthe Y axis and Z axis. From this point of view, it is advisable to place theobject s largest dimension along the X axis.Any surfaces that come into contact with support materials becomematte.Since high resolution models are built up, on the Z axis, in 16 or30 micron layers (according to the selected printing mode, it is verytime consuming to print a tall object. From this point of view, it isadvisable to place the object s smallest dimension along the Z axis.Since the print heads measure about 2 inches (5 centimeters) on theY axis, models measuring less than this (on the Y axis) are printed inone pass. From this point of view, it is advisable to place the object sintermediate dimension along the Y axis.Tall-Left RuleThis rule considers models where, after being orientated on the build trayaccording to other considerations, one side is taller than the other.Since the print heads move along the X axis from left to right, tallersections on the right require the print heads to scan unnecessarily fromthe left until reaching them. If, on the other hand, the taller sections arepositioned on the left of the tray, the print heads only have to scan themodel until printing these sectionsonce the lower parts have beencompleted. Therefore, you should position the taller side of the model,when possible, on the left.Recess-Up RuleThis rule considers models containing surface recesses.Recesses in the surface (like hollows, drill holes, etc.) should, whenpossible, be positioned face up.Fine-Surface RuleThis rule considers models that have one side on which there are finedetails (like the keypad side of a telephone).The side of the model containing fine details should, when possible, bepositioned face up. This results in a smooth finish.The following rules are based on the fact that support material is not required on the top of the printed model. D R A F T 16 June 2013
Using Objet Studio5–30 DOC-06800 Rev. AAvoid Support-Material RuleThis rule considers models that have large holes or hollows, open on atleast one side (like a pipe or a container).It may be advantageous to print a model standing up, so supportmaterial does not fill the hollow, even though printing the model lyingdown would be much faster.Manipulating Objects on the Build TrayPositioning Objects on the Z-AxisWhen you use the automatic positioning option to arrange objects on thebuild tray (see Automatic Orientation on page 5 26), the objects arepositioned directly on the tray. If you do not insert objects with automaticpositioning, they often appear either above or below the tray.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.Figure 5-35: Options dialog box, Settings tab2.

Operating & Maintaining the Objet1000 - Connex 2 3D Printer6–4 DOC-06800 Rev. ALoading Model and Support CartridgesObjet1000 Connex 2 printers use four containers of Model material andtwo containers of Support material, each weighing 18 kilograms when full.A graphical representation of the cartridges loaded and their currentweight appears in the printer interface (see figure 6 3).Important: If you need to replace the Model material currentlyinstalled with another type, see Changing the Model Materialon page 6 11. Otherwise, make sure to replace the Modelcartridge with one containing the same type of material.To load Model and Support material:1. On the side of the printer, pull open the doors of the storagecompartment.2. If you are replacing a material container, disconnect it from the feedtube. Then, grasp the handle and pull the container out of the printer.3. Load Model and Support containers into their respectivecompartments.4. Check the printer interface to make sure that the new cartridge isdetected and that its weight is displayed (see figure 6 3).5. Close the storage compartment door.The printer uses RFID technology to automatically identify cartridges of printing material. For this purpose, an RFID module is part of the printer hardware. Tampering with this module will render the printer inoperable and may void Stratasys warranties and service contracts.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.

Make sure that the build tray in the printer is empty and clean. If not,remove cured material with the scraper, and clean the tray thoroughlywith a wet cleaning cloth.2. Make sure that there is sufficient Model and Support material loaded,as indicated in the printer interface (see figure 6 3). You may want toreplace the cartridges of Model and Support material currently loadedin the printer to avoid the need for replacing them during printing.3. On the printer interface, click the red button to switch the printer toonline mode.The color of the button changes from red to green (see figure 6 4).

This isthe standard buffer between Objet Studio and the printer. As each slice isprinted, another slice is sent to the printer.Depending on the size of the model(s) to be produced, printing can takebetween several hours to several days. As long as there is enough Modeland Support material in the supply cartridges, printing proceedsautomatically until the job is finished.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 23). CAUTION: Use protective gloves when cleaning the build tray, and be careful of the sharp edges of the scraper blade.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.During printing, the server computer must remain on and it must communicate with the Objet printer.

DOC-06800 Rev. A 6–53Objet1000 - Connex 2 User GuideReplacing the Waste ContainerPrinter waste contains partially cured polymeric material, collected duringnormal operation and maintenance of the printer. For safety andenvironmental reasons, this material is kept in leak proof containers.monthsEach container has a capacity of 18 kilograms of waste material.The printer software displays a warning message when one wastecontainer is full and there is XX kilograms of material in the other container.The printer stops printing when the net weight in the second containerreaches XX kilograms. When the net weight in the second container isabove XX kilograms, the software does not allow you to start a print job (ora printing activity) until you replace one of the waste containers. You canmonitor the weight of the waste containers in the printer interface..Cleaning the Exterior PanelsThe painted exterior plastic panels of Objet 3D printers have a durablefinish, offering excellent chemical resistance to common cleaning materials.However, it is recommended that you use only a mild soap solution forroutine cleaning.Dispose of the full waste container in accordance with environmental and safety requirements.
