Safety Guidelines
The following general guidelines, together with the instructions provided
throughout this user guide, ensure user safety while operating and
maintaining the Objet system. If the system is not operated as specified,
the user s safety may be compromised!
Printer
Installation
Installation and removal of the printer should only be done by qualified
service personnel.
Connect the printer to the electric outlet using a power cord that is
safety certified.
The electric outlet should be easily accessible, near the printer.
Never connect the power plug to an outlet that does not have a ground
(earth) wire, and never disconnect the ground. Doing so might expose
the operator to serious danger from electric shock.
Leave a minimum of centimeters between ventilation openings and
walls or other objects.
Printer
Operation
The printer should only be operated by persons trained by a Stratasys
customer support representative.
All personnel operating or maintaining the printer should know the
location of first aid and emergency equipment and how to use it. Never
block access to this equipment!
Keep fingers and other body parts clear of the printer cover when
closing it.
Never attempt to open the main cover of the printer while it is working!
Never override the interlock safety switch!
If the interlock safety switch ever fails, do not use the printer.
Several parts of the printer remain extremely hot even after it has
stopped operating. Avoid touching the UV lamps and the print block.
UV Radiation
The UV lamps used in the printer emit dangerous radiation.
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 Stratasys
service provider.
Printer
Maintenance
Service operations should be performed only by qualified personnel
who have been instructed in relevant safety precautions.
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.

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.
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.
Keep model and support materials away from areas where food and
drink are stored, prepared and consumed.
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.
When handling UV cured models that may not be completely cured on
the surface, common latex gloves are adequate.
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.
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.
Do not wash contaminated clothing at home; clothing should be
professionally laundered.
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.

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.
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.
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.
Use cool water to prevent skin pores from opening, so that the liquid
material 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 results
in blisters, seek medical attention. In any case, if irritation persists, seek
medical attention.
Avoid the accidental transfer of printing material from the hands to
other areas of the body, especially to the eyes.
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.
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.
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 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.
If the victim has stopped breathing, perform artificial respiration or

Waste 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, wear
neoprene or nitrile gloves.
To prevent liquid waste from splashing into the eyes, wear safety
goggles.
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.
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.
Do not attempt to reuse empty cartridges, and do not puncture them.
Dispose of used cartridges and waste containers in accordance with
local regulations.
Discard contaminated clothing, shoes, empty containers, etc., in
accordance with any applicable regulations.

Introducing the Objet 3D 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 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 either 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.

Work Configurations
The Objet 3D 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 3D 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

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 3D printer, and
can prioritize and delete jobs, review job history and reprint a job, and so
on.

Introducing the Objet 3D Printing System
Source Files
Objet 3D printing systems produce three dimensional models designed
with most 3D CAD tools and with other job specific 3D 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 can be ASCII (text) files or binary files. The content of the ASCII
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.

Introducing the Objet 3D Printing System
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
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.

Work Environment
Extreme heat and humidity conditions can adversely affect the operation of
the Objet 3D 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 –25 C (64 –77 F)

Introducing the Objet 3D Printing System
Preparing Files for Use with Objet 3D Printing Systems
Before using files with Objet 3D 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 0.01 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 and
ASCII formats can be used in Objet Studio. However, binary files are
smaller, so this option is recommended.)
5. Click OK or Save.
For more information, search for “CAD to STL” on objet.com.
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 29.

Objet Studio Software
Objet Studio software for the Objet 3D 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 3D 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 3D 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 3D 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 3D 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
3D printers, but only to one at a time. The Job Manager screen displays the
status of the 3D printer to which the client is currently connected.

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 18
and in “Dividing Objects” on page 54.)
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.
Further explanations of files, and their features, appear throughout this
chapter.
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.

1. Open the Insert dialog box—
• From the Object menu, select Insert.
or—
• On the Tray Settings ribbon, click
or—
• Right click on the build tray, and select Insert from the context
menu.
The Insert dialog box appears.

3. In the Files of type field, select the file types to display (stl, slc, objdf).
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, as shown in figure 5 9.
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.

Copying and
Pasting
Objects
If you need to duplicate objects on the build tray, you can 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 use 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.

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.

Model-Material
Settings
Before placing objects on the build tray in Objet Studio, you should pay
attention to the material selection settings on the Tray Settings ribbon.
Figure 5-24: Material selection settings
• By default, the material selection settings on the ribbon correspond to
the 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 21).
• 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—
both 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 Tray Settings
ribbon, these settings are changed automatically. However, if there is an

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. Assign materials to the object (see “Assigning a Model Material to
Objects” on page 22).
5. Select the object and copy it.
6. Display the other Objet Studio window, and paste the object onto the
build tray.
Note: You can save the object with the new materials either as a new objdf
file, or by saving the original file with the changes.
Changing the
Model Material
When you design a build tray in Objet Studio, you can use model materials
that may not be currently installed in the printer. Because the installed
materials are displayed by default, change the material selection settings on
the Tray Settings ribbon, if necessary.
Digital
Materials
When two different model materials appear on the ribbon, you can produce
objects from either material or from a combination of them—digital
materials. Different pairs of model materials enable you to print objects
using unique digital materials. Certain digital materials can produce
objects with different shades of color. Combinations of model materials
that have different mechanical properties result in digital materials with
unique characteristics.

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 29.
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:
In the Insert dialog box, make sure Orient Automatically is not selected.
Figure 5-32: Orient Automatically option disabled
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 66.

Placement

Model Orientation
The orientation of models on the build tray affects how quickly and
efficiently they will be produced by the 3D 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 model s outer dimensions.
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
object s largest dimension along the X axis.
Any surfaces that come into contact with support materials become
matte.
Since high resolution models are built up, on the Z axis, in 16 or
30 micron layers (according to the selected printing mode, it is very
time consuming to print a tall object. From this point of view, it is
advisable to place the object s smallest dimension along the Z axis.
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 object s
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.
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.
The following rules are based on the fact that support material is not
required on the top of the printed model.
Recess-Up Rule
This rule considers models containing surface recesses.
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).
The side of the model containing fine details should, when possible, be
positioned face up. This results in a smooth finish.
DOC-06800 Rev. A
DRAFT
16 June 2013
5–29
Using Objet Studio
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).
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.
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 (see “Automatic Orientation” on page 5 26), 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.
Figure 5-35: Options dialog box, 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.

To ensure valid object placement:
1. From the Tools menu, select Constraints Settings.
Figure 5-36: Constraints Settings dialog box
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 (see “Tray
Validation” on page 47).
Note: Because of the unique characteristics of each type of model material
and finish, always check valid placement after changing the material/
finish. Remember that Objet Studio calculates the space occupied by
an object including the “bounding box” surrounding it (see

Production
Estimates
Objet Studio enables you to calculate the time and material resources

takes Objet Studio to perform this calculation depends on the number of
objects on the tray and their complexity. Calculating the production
estimate for a full tray could take up to 15 minutes, depending on your
computer’s specifications.
To calculate the time and materials needed for producing the current
tray:
On the Tray Settings ribbon, in the Build Process group, click
While the estimate is being calculated, a progress bar is displayed—on

Figure 5-68: Estimate progress bar
When Objet Studio finishes calculating the production resources, the
results are displayed in a dialog box.
Figure 5-69: Production resource calculations for different printing modes
As shown in the Production Estimates dialog box, the resources needed for
producing the models on the tray depend on the printing mode used by the
printer when producing the job. You might want to consider these
estimates when deciding on the printing mode (see below), and whether or
not to allow using substitute model materials when printing the job.
Note: You select the printing mode and material substitute options after
you send the build tray to the printer (see “Printing the Tray File” on
page 50).
Printing Modes Objet printers can build models using three possible printing modes.
HQ (High Quality) Mode—
• Models are printed in 16 micron layers, resulting in smooth surfaces,
suitable for producing fine detailed and delicate items.
• Almost twice as much time is required to print most trays, compared to
the High Speed setting.
• This setting is only available when model material can be used in four
print heads, in single material printing.

Single-material printing: All print heads print models without regard to the
source of the model material. This happens in the following situations:
• All print heads are supplied with one model material.
• Each pair of print heads is supplied with a different model material, but
models are printed as if they were the same material. The result is an
arbitrary mixture of materials in the printed model.
HS (High Speed) Mode—
• Models are produced in 30 micron layers, suitable for producing larger
models.
• Much less time is required to print most trays, compared to the
High Quality setting.
• This setting is only available when model material can be used in four
print heads, in single material printing.
Digital Material Mode—
• Used when producing models designed to be fabricated from two
model materials.
• Used when producing a tray containing two or more models, each
designed to be made from a different (single) model material.
• Used when producing models from only one of the model materials
loaded in the printer by printing with only two of the print heads.
• Models are produced in 30 micron layers, but the printing is near high
quality.
• Printing time is similar to printing time in High Quality mode.
Although printing time is longer than with High Speed mode, Digital
Material mode can make material replacement unnecessary—saving
both time and the cost of wasted model material.
Digital Material Mode is selected automatically when more than one model
material is assigned to objects on the tray.
You can see estimates of time and material resources needed for printing
trays using the different printing modes (see “Production Estimates” on
page 48). You also see these production estimates when you send the tray
to the printer. At that time, you can select the printing mode, including an
option that enables Objet Studio to print the tray by the most efficient
method (see “Printing Mode Selection” on page 50).

Objet Digital
Files
You can easily e mail objdf files using Microsoft® Office Outlook®. Sending
objdf files is recommended (instead of stl files) because the size of a file is

• If you require the job to be printed in High Speed mode, select this
option.
• If you do not require the job to be printed either in High Quality or
High Speed mode, select Automatic.
This setting enables the Objet software to determine (just before
printing) the most efficient way to print the tray. Digital Material mode
is used if this removes the need to perform the Material Replacement
procedure. Otherwise, High Speed mode is used.
For example, if printing the tray requires only one of the model
materials loaded in the printer, only the two print heads using that
material are used to print models—Digital Material mode. (High
Quality and High Speed modes call for printing model material with
four heads, which would require you to perform the Material
Replacement procedure.)
On the other hand, if printing the tray can be done using four print
heads without running the Material Replacement procedure, High
Speed mode is used. This is possible if all print heads are supplied with
one model material, or if you allow printing with an arbitrary mixture
of similar materials (see below).
Model Quality When Digital Material Mode is Used
• Near-high-quality is achieved for most models.
• A tray of objects inserted from stl files are printed with the standard
600 dpi (dots per inch) resolution along the Y-axis—unless glossy finish
is required (see “Surface Finish” on page 23).
• If there is an assembly on the tray, all of the models on the tray are
printed with a resolution of 300 dpi along the Y-axis.

“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. When using this
feature, called “Hollow,” the thickness of the shell should be no less than
0.5 millimeters.
To use the Hollow feature:
1. Select a model on the tray.

Exporting and
Importing
Objet Build
Trays
When you save build trays in Objet Studio, they are saved as objtf files.
These files contain instructions to Objet Studio and to Objet printers for
displaying and producing the stl files used on the tray. To conveniently
save all of the files that comprise the build tray, for storing the job, or for
transferring it to another location, Objet Studio compresses them into one
objzf file. To later use the objzf file, the file must first be expanded in Objet
Studio and its component files saved.
Note: If you export an objzf file containing a stl file originally saved as readonly, you cannot open (import) this objzf file to the folder where the
read-only stl file is saved.
To create an objzf file:
1. From the Objet Studio Commands Menu menu, select Export Packed
Job.
The Save As dialog box opens.
2. Select the appropriate folder and change the file name (if necessary).

selected folder, and the tray is displayed in Objet Studio.
Note: You can also export a print job as an objzf file from the Job Manager
screen—see “Exporting Jobs (objzf)” on page 83.

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 3D
printer—the server workstation.
• Objet Studio installed on a client computer only displays the queue and
status for jobs sent to the 3D 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
3D printer (server), displays the queue and status for all jobs sent to that
3D 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.

Loading Model and Support Cartridges
Objet1000 Connex 2 printers use four containers of Model material and
two containers of Support material, each weighing 18 kilograms when full.
A graphical representation of the cartridges loaded and their current
weight appears in the printer interface (see figure 6 3).
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.
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 material:
1. On the side of the printer, pull open the doors of the storage
compartment.
2. If you are replacing a material container, disconnect it from the feed
tube. Then, grasp the handle and pull the container out of the printer.
3.
Load Model and Support containers into their respective
compartments.
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 storage compartment door.
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.

Producing Models
The Objet1000 Connex 2 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 23).
To prepare the printer for producing models:
1. 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 thoroughly
with a wet cleaning cloth.
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 3). 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. On 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 4). 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.

Resuming Production After Printing has Stopped
If the printing process is interrupted, Objet Studio stops sending slices to
the printer. This can happen, for example, if the printing material runs out
in the middle of a print job, and you don’t replace the empty cartridge
immediately. After the printer changes to Standby or Idle mode, you need to
resume printing from the Job Manager screen of Objet Studio.
After printing stops, the printer goes into Standby mode, when heating of
print heads is reduced. About 10 hours later, the printer goes into Idle mode,
when heating of print heads is stopped.
To continue printing the model:
1. If the printer is in offline mode, switch it to online mode by clicking the
red button at the bottom of the printer interface (see figure 6 3 on
page 3).
The button changes from red to green (see figure 6 4 on page 6).
2. If you don’t know why printing has stopped, make sure that the
connection between the printer and the server computer is active.
3. In the Job Manager screen of Objet Studio, click the Resume icon
4. In the Continue from Slice dialog box that appears, confirm the slice
number, after checking the printer interface.

You cannot continue printing the model if:
• The number of the last slice printed does not appear in the printer
interface, even if the server computer displays the Continue from Slice
confirmation dialog box.
• There was a relatively long interruption in printing, even if the “last
slice” and “continue from slice” indicators are correct. The part of the
model already printed may deform or shrink, and there might be a
visible difference between it and the newly printed part. The effects of a
printing stoppage on a model depend on the model size and structure,
Model material used, ambient temperature and the length of the
stoppage.
If you cannot continue printing:
1. Cancel the print job in the Job Manager screen.
2. Remove the partially printed model from the build tray.
3. Restart the job from the Job Manager screen (in Objet Studio).
You can stop and later resume printing from either the printer interface or
from the Job Manager screen of Objet Studio. After clicking the Stop button
on the printer interface, you can resume printing only from the Job Manager
screen. However, after clicking the Pause button in the printer interface, you

Changing the Model Material
Before producing models using a different type of Model material than is
currently installed, run the Material Replacement Wizard to flush the print
block and feed tubes.
You should carefully plan printing models with different Model materials to
avoid unnecessary waste of the materials currently loaded. The amount of
material flushed depends on the flushing cycle chosen and if you are
replacing one or both Model cartridges.
To replace the Model material:
1. Start the Material Replacement Wizard from the Options menu.

• 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 52).
6. In the Required materials section of the wizard screen, select one or more
replacement materials.
7. Select Both cartridges if you need to load two replacement cartridges.

Shutting Down the Printer
You only need to shut down the Objet printer if it will not be used for a
week or more. Otherwise, the printer can remain on, in Idle mode.
The Shutdown process flushes printing materials from printer components.
To avoid flushing out valuable material, make sure to print models at least
once a week. Many printer operators use this opportunity to print customer
samples or test models.
To properly shut down, the printer needs to perform several processes.
These are controlled by the Shutdown Wizard. Do not attempt to shut
down the printer by simply closing the computer interface (the printer
control application), and never disconnect power to the printer before
completing this wizard.
Depending on the length of time the printer will not be used, you can
choose between a short shutdown procedure, and a more thorough
procedure.
• Up to 10 days: The wizard empties the print block of Model and
Support material, to prevent leaks. This takes about 10 minutes.
• More than 10 days: The wizard empties the print block, then flushes
the system with cleaning fluid. This takes up to 35 minutes, and you
must be present to load cleaning fluid cartridges when instructed.
To run the Shutdown Wizard:
1. Start the Shutdown Wizard from the Options menu.

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 23). 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 the Options menu, select Purge Sequence, or press F4.
2. In the confirmation dialog box, click Yes.
The print heads are purged of Model and Support material, and the
wiper removes excess material from them.
3. Repeat the purge sequence.
4. Perform the pattern test.
If the results of the pattern test are still poor:
1. Manually clean the print heads (see “Cleaning the Print Heads” on
page 6 20).
2. Perform the purge sequence.
3. Perform the pattern test.
If the results of the pattern test are still poor:
1. Carefully clean the print heads again, making sure there is no residue
left on them.
2. Perform the purge sequence.
3. Perform the pattern test.
If the results of the pattern test are still poor:
Consult with your Stratasys service provider about replacing faulty
print heads.
Cleaning and
Replacing the
Wiper
A rubber wiper removes excess material from the print heads after the
purge sequence. This is done automatically before each print job, and
performed manually during maintenance tasks. You should clean the
wiper and surrounding area at least once a week. If the wiper is damaged
or worn, replace it.
To inspect and clean the wiper:

Replacing
Print Heads
The condition of the print heads directly affects the quality of printed
models. You may need to replace a print head if one or more of the
following symptoms occurs:
• There are noticeable grooves in the surface of printed models.
• Visual inspection of the head reveals that its surface is damaged—
peeling or bubbles in the nozzle area.
• The printer interface displays a warning or malfunction message
relating to a print head—
Head Heater temperature timeout
Head Heater thermistor open
Head Heater thermistor short
Replace print heads only after consulting with an authorized customersupport engineer.
Testing and
Calibrating the
UV Lamps
The effective UV radiation from the lamps used for curing models can
change over time. To ensure optimum curing of models during printing, a
pop up message reminds you to test the lamps and calibrate their effective
UV radiation after every 300 hours of printing. You do this by running the
UV Calibration Wizard with an external UV radiation meter.
The wizard compares the radiation you measure to the recommended
radiation level for each of the lamps, at each printing mode—High Speed,
High Quality and Digital Material.
When calibrating the lamps, the wizard attempts to adjust the radiation
level, if necessary, and then prompts you to take a new reading.
• If the reading is within the acceptable range, the wizard continues to
the next phase.
• If further adjustment is necessary, the current phase is repeated.
• If the UV radiation is too low to be properly adjusted, the wizard
continues to the next phase, but the final wizard screen indicates that
the lamp’s radiation for the printing mode is unacceptable.
Before testing and calibrating the UV lamps:
• Make sure the glass lens on the UV lamp is clean. For easy access, run
the Head Cleaning Wizard, and use the special cleaning pad supplied.
• Make sure that the UV radiation sensor is available to you, and that its
protective glass is clean.

Built-in Tests
The printer application contains a suite of tests for regularly checking the
hardware and software, and for troubleshooting. You can configure basic
communications and environment tests to run automatically, when the
Objet software opens. In addition, you can run a more comprehensive set of
tests before processing a print job, as a system check, to ensure optimum
printing results.
Because running the tests effects the operation of the printer, you can only
open the Built in Tests interface when the system is not printing.
The test suite features:
• The organization of printing related tasks in categories:
Communications
Data cards
Temperatures
Voltages
Encoder repeatability
Print head heating
Print head filling
• A clear display of test results and the source of any failures, enabling
you to determine if printing is possible or worthwhile.
• The ability to monitor test results for specific components.
• Troubleshooting tips.
Running these tests can help identify problems in the printer hardware and
software. A large number of hardware defects (or near defects) warns you
of possible printing problems, either for current or future jobs.
Stratasys recommends running the built-in tests in the following cases:
• as a routine test, once every two weeks
• as a system check, before major (long) jobs
• as needed, for troubleshooting

Replacing the
Waste
Container
Printer waste contains partially cured polymeric material, collected during
normal operation and maintenance of the printer. For safety and
environmental 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 waste
container is full and there is XX kilograms of material in the other container.
The printer stops printing when the net weight in the second container
reaches XX kilograms. When the net weight in the second container is
above XX kilograms, the software does not allow you to start a print job (or
a printing activity) until you replace one of the waste containers. You can
monitor the weight of the waste containers in the printer interface.
Dispose of the full waste container in accordance with environmental and
safety requirements.
.Cleaning
The painted exterior plastic panels of Objet 3D printers have a durable
the
Exterior Panels finish, offering excellent chemical resistance to common cleaning materials.
However, it is recommended that you use only a mild soap solution for
routine cleaning.
