Page 26: Welcome To Connex™ Printing
Objet260 User Guide 3 Introducing the 3D Printer Welcome to Connex™ Printing The advanced capabilities of Connex printing systems are made possible by technology specially developed by Stratasys for producing 3D prints simultaneously with different model materials. Printing 3D prints with combinations of basic materials (digital materials) enables you to choose from a wide range of mechanical properties—from flexible to rigid—and colors. With Connex printers, you can achieve the following results for 3D prints: • You can prepare 3D prints for production using 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 3D prints. • You can print parts of the same 3D print—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 3D prints: • Producing 3D prints 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 the model materials loaded (or material combinations)—again, without the need and expense of replacing materials. Print jobs can be set up and sent to the printer with either of these applications: • Objet Studio • GrabCAD Print (Connex3 printers only) These applications are described in the following chapters. Objet Studio enables you to split 3D prints into component parts (“shells”) so you can isolate, manipulate and print parts of a model. Then, you can assign model materials and other characteristics to the shells. However, you have ultimate control when separating parts into shells by preparing stl files with your CAD software.
Page 27: Work Configurations
Objet260 User Guide 3 Introducing the 3D Printer Work Configurations Objet260 3D printing systems can be set up as single-station systems or as multi-station systems. When connected to a local computer network, the system can serve multiple users. In such configurations, each user (client) prepares files f or production. A server, typically next to the printer, sends jobs to the printer. Figure 3-1 shows the printer set up in a multi-client configuration. Figure 3-1 Multi-client network configuration When jobs are sent to the printer, Job Manager, on the server computer, arranges them 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 printer, and can prioritize jobs, delete jobs, review job history and reprint jobs.

Page 28: Source Files
Objet260 User Guide 3 Introducing the 3D Printer Source Files Objet260 printing systems produce 3D prints designed with most CAD tools and some other 3D applications. Objet Studio supports these file formats: • STL • SLC • VRML GrabCAD Print (for Connex3 printers) supports STL, VRML, OBJ and 3MF files. In addition, GrabCAD Print supports native CAD formats from these programs: Creo, SOLIDWORKS, NX, CATIA and Inventor. To see the complete list of file formats supported by GrabCAD Print, go to: help.grabcad.com/print/file-formats. All Objet260 systems feature the capability of producing different types of f iles simultaneously. STL Files STL is short for STereoLithography or 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. Most CAD software can export STL files. Objet Studio/GrabCAD Print opens these files for printing on the p rinter. SLC Files SLC is short for Stereo-Lithography Contour. SLC files describe 2D contours of ...
Page 29 Objet260 User Guide 3 Introducing the 3D Printer When you create a VRML file in a CAD program, two files are created: a wrl file, containing the 3D print's geometric information, a nd a picture file ( bmp, png, jpg, or tiff), containing the 3D print's color information. When you create a VRML file in most CAD programs, two files are created: a wrl file, containing the 3D print's geometric information, including texture, and a picture file ( bmp, png, jpg, or tiff), containing the 3 D print's color information. Before placing a VRML file on the b uild tray, make sure that the VRML file and its corresponding picture file are in the same folder. DOC-37004 Rev. J...
Page 30: Printing Materials
Objet260 User Guide 3 Introducing the 3D Printer Printing Materials Objet260 printers produce 3D prints by jetting thin layers of printing materials on the build tray, until the complete 3D print is formed. Two types of material are used in this process: • Model material—which makes up the finished 3D print. • Support material—which fills gaps and spaces in the part during printing, and is removed after printing. For up-to-date information about PolyJet printing materials and their properties, go to www.stratasys.com/materials/polyjet. Storage Materials used for producing 3D prints with Objet260 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. • 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 15–27 degrees Celsius (59-81 degrees Fahrenheit). If exposed to heat or flames, cartridges might burst or ignite. • Signs of premature polymerization in material cartridges include bulging, leaking, the emission of heat, and unusual odor. Exposure to heat can cause resin to gel in the cartridges. • Make sure that material cartridges are stored in accordance with all local regulations and other applicable requirements. Shelf Life Materials used for producing 3D prints have a limited shelf life. The expiry date ...

Page 51: Preparing Models For Production
Objet260 User Guide 5 Using Objet Studio 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 Objet260 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 5-21 and in "Dividing Objects" on page 5-61.) 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 Objet260 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.

Page 53 Objet260 User Guide 5 Using Objet Studio Therefore, when saving VRML files in a CAD program, a bmp file of the assembly should be saved. You can open several stl files (and VRML files) 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. Figure 5-8 Assembly check box selected—stl files are placed as an assembly Figure 5-9 Assembly check box not selected—stl files are placed as parts The Model Settings ribbon is displayed when objects are placed on the build tray.

The 3D file contains the object's proportions, but not its units of measure. Therefore, make sure to correctly select either millimeters or inches when inserting an object. Otherwise, the size of the object on the build tray will be either much too large or much too small. To change the measurement units of objects already placed on the tray, see "Measurement Units" on page 5-36. ❒ Number of copies—How many copies of this object to place on the build tray. ❒ Orient Automatically—Automatically orient objects on the build tray for efficient model building. ❒ Assembly—Mark this check box if you selected multiple stl files that are part of an assembly.

Page 61: Copying And Pasting Objects
Objet260 User Guide 5 Using Objet Studio 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 on another tray before inserting the object. 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.

Page 62: Surface Finish
Objet260 User Guide 5 Using Objet Studio Surface Finish Models can be printed with a matte or glossy surface finish. To create a matte finish, the printer surrounds models with a thin layer of support material. To set the model finish: 1. Select the model. 2. Select Matte or Glossy in one of the following places: ❒ Model Settings ribbon, Options group ❒ Model Toolbar ❒ right-click context menu (when selecting the model) You can configure Objet Studio to distinguish between objects’ surface finish on the build tray by color. To configure how Objet Studio displays objects, see "Setting Object Colors" on page 5-49. Splitting Objects into Components 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 ...

Objet260 User Guide 5 Using Objet Studio 2. With the object selected: ❒ From the Object menu, select Separate into Shells. or— ❒ On the ribbon, click A dialog box opens in which you can specify where to save the component stl files. (By default, Objet Studio offers to save the new files in a folder in the same location as the original stl file.) Figure 5-20 Folder selection for saving stl files after splitting into shells 3. Click OK. Objet Studio splits the object into an assembly of component parts, each a separate stl file (“shell”). The object appears—on the build tray and in the model tree—as an assembly of parts (“shells”). You can assign each part a different model material (This is explained in "Model-Material Settings" below). Figure 5-21 Object after being converted to an assembly of component parts Model-Material Settings Before placing objects on the build tray in Objet Studio, you should pay attention to the material selection settings on the Tray Settings ribbon. Figure 5-22 Material selection settings DOC-37004 Rev. J 5-22...
Page 64 Objet260 User Guide 5 Using Objet Studio • By default, the material selection settings on the ribbon correspond to the three Model cartridges loaded in the printer. • The materials displayed are basic model materials. With Connex2 and Connex3 printers, these materials can be combined to create digital materials (see "Digital Materials" on page 5-25). • The material displayed on the top (VeroBlack, in the figure above) is considered the primary model material (“Model-1”). It is assigned to objects that do not have a material assignment when you place them on the build tray. For example, since stl files do not contain information about the model material, Objet Studio assigns the primary model material to them. Also, if you try to insert objdf files whose assigned materials are not recognized by your version of Objet Studio, you can insert the file by substituting the primary model material for the missing materials. • Select Single Material if you want to print using only one material—all of the material drop-down menus contain the same material. If you decide to print with multiple materials, the material in the top drop-down menu remains assigned to the object until you select another material. • If you insert an objdf file into an empty build tray, and the model-material assignment does not match the settings on the Tray Settings ribbon, these settings are changed automatically. However, if there is an object already on the build tray whose materials do not match the material assignment in the objdf file, you cannot place the new object on the tray. To print this object, you have the following options: ❒ Instead of printing it on the same build tray, print the new object as a separate job. ❒ Change the materials assigned to objects on the build tray to match ...
Page 65: Changing The Model Material
Objet260 User Guide 5 Using Objet Studio Changing the Model Material When you design a build tray in Objet Studio, you can use model materials that might 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. Figure 5-23 Selecting a new model material Changing the Support Material To change the type of Support material: 1. In the printer application, run the Material Replacement Wizard (see "Changing the Printing Material" on page 6-13). 2. In Objet Studio: ❒ When changing to SUP706, the recommended Grid Style is "Lite." Note: Cleaning models printed with Standard or Heavy grid style can clog the filter in DT3 and CS P cleaning stations. If necessary, clean these models with a WaterJet cleaning station. ❒ When changing to SUP705, the recommended Grid Style is "Standard." You can override the default grid style settings for the current print job in the Advanced Properties dialog box (see "Choosing the Support Strength" on page 5-62).

Page 70: Positioning Objects On The Build Tray
Objet260 User Guide 5 Using Objet Studio Positioning Objects on the Build Tray To produce models efficiently and with the required finish, it is important to carefully position objects on the 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 "Manual Positioning" on page 5-31. Two things that affect the positioning of objects on the 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.

Page 95: Handling Trays
Objet260 User Guide 5 Using Objet Studio Handling Trays After preparing models on the build tray, you can do the following: • Test that it can be printed ("validation"). • Calculate the time and material resources needed to print it. • Send it to the printer for production. • Save it for later completion or printing. • Save it as a compressed file for convenient storage and transfer. Tray Validation Before sending a job to the printer for production, you should check that the tray is “valid” and can be printed. Note: Because of the unique characteristics of each type of modeling material, make sure that the correct material is selected before performing Tray Validation. To validate that the tray can be printed: ➢ On the Tray Settings ribbon, in the Build Process group, click or— From the Tools menu, select Placement Validation. If the tray is not valid, the color of the problematic models on the tray changes according to a pre-set code.

Page 97: Printing Modes
Objet260 User Guide 5 Using Objet Studio Printing Modes Objet260 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 ...

Page 104: Hollow"- Filling Models With Support Material
Objet260 User Guide 5 Using Objet Studio “Hollow”— Filling Models with Support Material Many objects placed on the tray from stl files are “solid.” This means that, when printed, the model will be completely filled with model material. Often, especially with large objects, this is unnecessary. Instead, the model can be filled with support material, which is less costly. It is also advisable to fill models with support material when preparing them for investment casting, since this material burns off more quickly during the process of making the cast. Objet Studio enables you to print objects on the tray with an outer shell of model material and a center filled with support material. 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. Select Hollow.

Page 121: Monitoring And Managing Print Jobs
Objet260 User Guide 5 Using Objet Studio 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 PolyJet 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 PolyJet printer. Later, these files can be used by Objet Studio on the appropriate printer server. DOC-37004 Rev. J 5-80...

Page 165: Uv Lamp Check
Objet260 User Guide 6 Operating and Maintaining the Printer UV Lamp Check A heat-sensitive label is fixed to the UV lamp covers as a warning against overheating. Its center changes from white to black if the temperature of the cover reaches 65°C (150°F). If this occurs, do not use the printer, and call your service provider. As a precaution, it is recommended that you check the label before and after printing. Figure 6-25 Heat-sensitive label on UV lamp cover If the UV lamp continues to overheat, and the temperature around the lamp reaches 90°C (194°F), a heat fuse turns off the electricity to the power to the UV lamp and the motors for the X, Y, and Z axes. In the unlikely event that this occurs, the printer cannot be used until it is serviced by an authorized service engineer.

Objet260 User Guide 6 Operating and Maintaining the Printer 7. Carefully inspect the test paper to see if there are missing lines. Too many missing lines, especially if they are in the same area, indicates that the quality of printing when producing 3D prints will be poor. If this is the case, see "Improving Print Quality" below. Note: Acceptable 3D print quality is subjective, and depends on the type and scale (size) of the 3D prints 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 6-34). 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.

Page 226: Replacing The Waste Container
Objet260 User Guide 6 Operating and Maintaining the Printer 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 a special leak-proof, disposable container. The container has a capacity of about 8 kilograms of waste material—usually enough for several months of printer use. The printer application displays a warning message when there are 7.3 kilograms of material in the container, and stops the printing when the net weight reaches 7.8 kilograms. Above 7.3 kilograms, the software does not allow you to start a printing job or activity until you replace the waste container. You can monitor the weight of the waste container in the Printer Indicators display in the printer interface. You can also visually inspect the level of waste in the container. To access it, see page 6-91. 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.

Objet260 User Guide 7 Handling Printed Models To clean a 3D print using this device, you manipulate it and the water using the built-in, waterproof sleeves. A pump turns ordinary tap water into a high- pressure jet. A wiper keeps the window clear. Use caution when cleaning delicate 3D prints with high-pressure water systems. Removing S UP705/705B with Caustic Soda Soak 3D prints in a 1-percent solution of caustic soda (sodium hydroxide) to remove support material from difficult-to-reach areas and to give the 3D print a smooth, clean finish. The amount of time you soak the 3D prints 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 it thoroughly (with a water jet) afterwards. Warning Caustic soda may cause chemical burns, scarring and blindness. Mixing it with water generates heat that could ignite other materials. Never pour water into caustic soda. When diluting the solution, always add caustic soda to water. Take adequate safety precautions; always use nitrile gloves when handling caustic soda and 3D prints soaked in it. Removing SUP706/706B with Caustic Soda and Sodium Metasilicate Soak 3D prints in a 2-percent solution of caustic soda (sodium hydroxide) and sodim metasilicate (Na ) to remove support material. The amount of time you soak the 3D prints in the solution depends on how delicate it is and how much support material needs to be removed. Rinse the 3D print thoroughly under running water afterwards. SUP706/706B will dissolve into the caustic soda and sodium metasilicate solution and saturate it, reducing its effectiveness. Replace the solution when the support material reaches 15% of the solution (after approximately one month of average use). Warning Caustic soda may cause chemical burns, scarring and blindness. Mixing it ...
Page 235: Post-Printing Treatment
Objet260 User Guide 7 Handling Printed Models Post-Printing Treatment Post-printing treatment is recommended for 3D prints with several special- purpose materials or for special applications. Recommendations for treating and finishing 3D prints after printing are described in the Best Practices for the desired printing material available on the Stratasys Support Center. Photobleaching for Transparent 3D Prints 3D prints fabricated with clear materials, such as VeroClear (RGD810) and have a slight yellow tint when removed from the printer. This is especially true for 3D prints with a glossy finish. The yellow tint fades naturally over time, but you can greatly accelerate this process by using a suitable photobleaching treatment. This involves exposing 3D prints to intense light immediately after printing. Photobleaching methods and instructions are described in the Best Practices for the relevant clear material. These are available on the Transparent materials page on the Stratasys Support Center. Refer to the Best Practices for: VeroClear RGD810 Storing 3D Prints 3D prints 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 3D prints at room temperature and in a low-humidity environment. • Do not expose 3D prints to direct sunlight and other heat sources.
