Page 17: Model And Support Materials
Objet260 User Guide Model and Model and support materials are made of chemical substances. Although Support precautions must be taken when handling these materials directly, all Materials 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 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. If the printer is not equipped with an exhaust duct, the room ventilation system should 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 ...

Page 19: Waste Disposal
Objet260 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 (uncured printing material). Printing Materials 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. UV Lamps UV lamps used by the printer to cure printing materials contain a small amount of mercury, and are considered “Universal Waste.” Recycle or discard used lamps in accordance with applicable regulations. Broken lamps: After ventilating the area, use protective gloves and carefully remove spilled mercury with a method that prevents the generation of mercury vapor, such as a syringe, packing tape or paper. Place the broken lamp, mercury and contaminated materials in an air‐tight, non‐metallic container. Dispose of the container in accordance with applicable regulations. 2–7 DOC-37000 Rev. B...

Page 22: Welcome To Connex
Introducing the Objet260 3D Printing System Welcome to Connex The advanced capabilities of Connex™ 3D printing systems are made possible by technology specially developed by Stratasys for printing models simultaneously with different model materials. Connex‐2 and Connex‐3 configurations offer the additional capability of printing models with combinations of basic materials (digital materials), enabling you to choose from a wide range of mechanical properties—from flexible to rigid. With Connex printers, you can achieve the following results when printing 3D models: • You can prepare objects for printing with two or three designated model materials and then print them at the same time. This enables you to assign specific mechanical and color properties to objects. • You can print parts of the same model—simultaneously—with different materials (or material combinations • You can print objects that have a “coating” made from a different material than the main part of the object. Because Connex printers can be loaded with different materials, you can streamline and economize the process of producing models: • Printing models made from different materials on the same build tray (“mixed tray”), in the same print job, 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 using any of the model materials loaded (or material combinations)—again, without the need and expense of replacing materials. Objet Studio enables you to split models into component parts (“shells”) so you can isolate, manipulate and print parts of a model. Then, you can ...
Page 23: Work Configurations
Objet260 User Guide 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 workstations Printer server KVM switch Printer workstation Printer Figure 3-2: Multi-client network configuration When installing Objet Studio, you choose whether to install it as a client station or as a master station (server or standalone station). Objet Studio 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 3–3 DOC-37000 Rev.

Page 24: Source Files
Introducing the Objet260 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 • VRML Files (for Connex 3 systems) Objet systems feature the capability of producing different 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. ...

Page 26: Printing Materials
Introducing the Objet260 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 For up-to-date information about PolyJet printing materials and their properties, go to http://www.stratasys.com/materials/polyjet. 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 PolyJet printing materials.
Page 27: Safety Considerations
Objet260 User Guide Safety Before being cured, resins are hazardous materials. To prevent possible Considerations 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.

Page 45: Preparing Models For Production
Objet260 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 19 and in “Dividing Objects” on page 53.) OBJDF Files: An objdf file describes both the geometry of a single object and the Overview 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 ...

Page 53: Copying And Pasting Objects
Objet260 User Guide Copying and If you need to duplicate objects on the build tray, you can insert the same Pasting object from its file more than once. An easier way, however, is to copy and Objects 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.
Page 54: Selecting Objects
Using Objet Studio Selecting To manipulate an object on the build tray or assign characteristics to it Objects (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 keys while clicking additional objects. Shift Alternatively, select or de‐select objects using the following Edit menu commands: • Select All • Invert Selection • Undo Select object Figure 5-19: Edit menu Sometimes, you need to select individual elements of an assembly.

Page 55: Splitting Objects Into Components
Objet260 User Guide Splitting You can convert a complex object to an assembly of component parts. To do Objects into so, you split the stl file that represents the object into a group of separate stl Components 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. 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 10). 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 20.) Figure 5-21: 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.

Page 63: Positioning Objects On The Build Tray
Objet260 User Guide 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 optimally for your needs, according to the considerations explained in “Model Orientation” on page 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 By default, Objet Studio automatically orients objects, when placed on the Orientation 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 5-35: Orient Automatically option disabled...
Page 64: Automatic Placement
Using Objet Studio Automatic After placing several objects on the build tray, you can let Objet Studio Placement arrange them before printing.

To automatically arrange objects on the build tray: 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 5-36: Tray before objects are properly arranged Figure 5-37: Tray arrangement after applying Automatic Placement 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.
Page 65: Manual Positioning
Objet260 User Guide Manual You can change the position of objects on the build tray—even if they were Positioning inserted with the Orient Automatically option. Considerations for positioning objects are presented in “Model Orientation,” below. Tools for changing the position of objects are presented in “Manipulating Objects on the Build Tray” on page 30. 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 modelʹs 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 objectʹs largest dimension along the X‐axis. Any surfaces that come into contact with support materials become matte. Since models are built up, on the Z‐axis, in 16‐ or 30‐micron layers (according to the printing mode), 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. 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. Since the print heads move along the X‐axis from left to right, taller ...
Page 66: Manipulating Objects On The Build Tray
Using Objet Studio 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. 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 When you use the automatic positioning option to arrange objects on the Objects on the build tray (see “Automatic Orientation” on page 27), the objects are Z-Axis 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 one- millimeter bed of support material.

Using Objet Studio Choosing the When producing models, support material fills some hollow and empty Support sections (see “Model Orientation” on page 29). Objet Studio allows you to Strength adjust the strength of the structure formed with the support material. This adjustment is useful when producing either large/massive models or small/ delicate models. For most purposes, the default setting provides adequate support strength. To change the strength of the support structure used when printing a model: 1. Select a model on the tray. 2. On the Model Settings ribbon, in the Options group, click or— • On the Model Toolbar, click or— • From the right‐click context menu, select Advanced Properties The Advanced Properties dialog box opens.

Page 91: Hollow"- Filling Models With Support Material
Objet260 User Guide “Hollow”— Many objects placed on the tray from stl files are “solid.” This means that, Filling Models when printed, the model will be completely filled with model material. with Support Often, especially with large objects, this is unnecessary. Instead, the model Material 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. or— • On the Model Toolbar, click or— • From the right‐click context menu, select Advanced Properties The Advanced Properties dialog box opens. 2.

Page 125: Producing Models
Objet260 User Guide Producing Models The Objet260 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” in this user guide or Objet Studio Help. Preparing the Printer 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 24).

Page 129: Resuming Production After Printing Has Stopped
Objet260 User Guide 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.
Page 130 Operating & Maintaining the Objet260 3D Printer 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.
Page 131: Changing The Printing Material
Objet260 User Guide Changing the Printing Material Before producing models using a different type of printing 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 more Model cartridges.

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 5‐51).
Page 133 Objet260 User Guide enables continuous printing until the print job is completed. When one cartridge empties and the other one is being used, you can replace the empty cartridge with a new one. 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.

Page 192: Replacing The Waste Container
Operating & Maintaining the Objet260 3D Printer Replacing the Printer waste contains partially cured polymeric material, collected during Waste normal operation and maintenance of the printer. For safety and Container 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 application displays a warning message when there are 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 73.) To monitor the waste weight (and other indicators) in the printer: In the main printer interface screen, click the display toggle to view the printer indicators. Waste weight...

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. While wearing protective gloves, break away excess support material on Removing Excess Support Material by the outside of the model. For delicate models, use a toothpick, pin or small Hand brush after dipping the model in water. Removing Support For most models, the most efficient way to remove support material is by Material with Water using a high‐pressure water jet. One suitable system is the Objet WaterJet cleaning unit. This device is marketed by Stratasys. Pressure 7–2 DOC-37000 Rev. B...
Page 197 Objet260 User Guide Figure 7-1: Objet 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. Soak models in a 1‐percent solution of caustic soda (sodium hydroxide) to Removing Support Material with remove support material from difficult‐to‐reach areas and to give the Caustic Soda 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.
Page 198: Post-Printing Treatment For Models Printed With Objet Veroclear
When using desk lamps, place the models in a container lined 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 Stratasys laboratories, there was a tint reduction of approximately 70% within six hours. After 24 hours, tint was reduced by approximately 90%. More information about this treatment is available in the application note VeroClear RGD810 Model Material. 7–4 DOC-37000 Rev. B...
Page 199: Storing Models
Objet260 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. 7–5 DOC-37000 Rev.
