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.
Objet1000 - Connex 2 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.
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.
Objet1000 - Connex 2 User Guide Connex Workflows With Objet Connex 3 D printing systems, you have great flexibility in preparing model files and printing them. Below are the major workflows that have been made possible by PolyJet Matrix technology on Connex systems. You can find detailed instructions for implementing the listed tasks in chapter 5 (Using Objet Studio). Stage Workflow A Workflow B CAD program • Design a 3 D object. • Save as a single stl • Design a 3 D object.
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.
Objet1000 - Connex 2 User Guide Disposal Dispose of cartridges of Objet model and support material in accordance with all applicable laws and regulations. If necessary, the cartridges can be disassembled for recycling. Work Environment Extreme heat and humidity conditions can adversely affect the operation of the Objet 3D printer.
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.
Objet1000 - Connex 2 User Guide 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.

Using Objet Studio Objet Studio Commands Menu Clicking the icon in the upper left corner opens the Objet Studio Commands menu. This menu displays basic application commands and options. Figure 5-7: Objet Studio Commands menu The Options button opens a dialog box for customizing Objet Studio. Figure 5-8: Options dialog box Model Tree Pane 5–8 The Model Tree pane lists the objects placed on the build tray in a parent child hierarchy.
Objet1000 - Connex 2 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 objects 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.
Using Objet Studio Placing Objects on the Build Tray To place an object on the build tray using stl, slc or files: 1. Open the Insert dialog box • From the Object menu, select Insert. or • On the Tray Settings ribbon, click . or • Right click on the build tray, and select Insert from the context menu. The Insert dialog box appears. Figure 5-9: Insert dialog box 2. In the Look in field, display the appropriate folder. 3.

Select any of the following options, as required: • UnitsMillimeters or inches for the objects units of measure. 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.
Using Objet Studio 6. Click Insert. Objet Studio places the object on the build tray, and in the model tree. Model Tree pane Model Toolbar Figure 5-12: Default screen layout The Model Settings ribbon is displayed when objects are placed on the build tray. If the object is over a certain size, the Loading Placed Elements dialog box may appear.
Objet1000 - Connex 2 User Guide Opening files Before placing files on the build tray, Objet Studio must extract the component stl files together with information about their relative position and model materials. To do this, Objet Studio creates a folder with the same name as the file, in the same location. Figure 5-14: Insert dialog box (file) DOC-06800 Rev.
Using Objet Studio Opening Objet Tray Files You can open trays that were saved as objtf files. This is useful, for example, if you saved a tray after preparing it for printing, and now you want to make changes before printing it. To place an object saved as an Objet Tray File (objtf) file on the build tray: 1. From the File group, click . or From the Objet Studio Commands, select Open. The Open dialog box is displayed. Figure 5-15: Objet Tray File Open dialog box 2.
Objet1000 - Connex 2 User Guide STL file loading If there are identically named stl files in more than one location, you need preference to ensure that the correct component stl files are linked to the objtf file. For example, if there are identically named stl files on one drive and on a flash drive (this can occur if you copy the original files to a working folder), you can set the default location from which files are loaded. To set the Load Order: 1. From the Tools menu, select Options.
Using Objet Studio Quick-Access Model Commands Model Toolbar You can access common commands for working with objects on the build tray with the convenient Model Toolbar and context menus. Select an object in the tray to display the Model Toolbar that contains icons to perform common tasks. Figure 5-17: Model Toolbar The table below describes the Model Toolbar icons. Icon Description Applies a matte finish to the model. Applies a glossy finish to the model.
Objet1000 - Connex 2 User Guide 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 treeindividual or multiple parts or assemblies. The objects copied remain in the Windows clipboard until you paste them onto the build tray.
Using Objet Studio Selecting Objects To manipulate an object on the build tray or assign characteristics to it (model material, building style etc.), you must first select the object. You select an object by clicking it, either on the tray or in the model tree. Its image on the build tray changes color (to light blue, by default) and its name is highlighted in the model tree.
Objet1000 - Connex 2 User Guide To split an object into an assembly of component parts: 1. If the object is not displayed, place it on the build tray by inserting its stl file (see Placing Objects on the Build Tray on page 10). The object appearson the build tray and in the model tree paneas a single part. It is assigned, by default, the primary model material. (If Objet Studio is configured with a secondary material, you can assign itor a digital materialto the entire object.
Using Objet Studio Objet Studio splits the object into an assembly of component parts, each a separate stl file (shell). The object appearson the build tray and in the model treeas an assembly of parts (shells). You can assign each part a different model material (This is explained in Model Material Settings on page 20).
Objet1000 - Connex 2 User Guide object already on the build tray whose materials do not match the material assignment in the objdf file, you cannot place the new object on the tray. To print this object, you have the following options: Instead of printing it on the same build tray, print the new object as a separate job. Change the materials assigned to objects on the build tray to match those assigned to the new object (see Changing the Model Material and Assigning a Model Material to Objects, below).
Using Objet Studio To view the digital materials available for printing objects (using two basic model materials): 1. Make sure that you have selected the appropriate model materials, and that Multiple Materials is selected. Figure 5-25: Material selection with two basic model materials 2. Click . The Material Selection Guide appears, showing the basic model materials (at the top of the list) and the digital materials available (combinations of them).
Objet1000 - Connex 2 User Guide 2. Display the material pull down menu and select the desired material. Figure 5-28: Menu for assigning materials to objects When you de select the object on the build tray, it is displayed, by default, with the color of the material you selected. In the same way, you can assign model materials to each of the independent objects on the build tray. To separate an object into independent, component parts (each an stl file), see “Splitting Objects into Components” on page 18.
Using Objet Studio 3. Select Coat With and, from the pull down menu, select the coating material. Figure 5-29: Coating material selected 4. In the Thickness field, enter a coating thickness between 0.3 and 3 millimeters. Note: The coating thickness does not affect the external dimensions of the object, which remain unchanged. The coating layer replaces part of the main model material. 5. Click Apply.
Objet1000 - Connex 2 User Guide Assigning Properties to Hidden Objects To enable you to assign materials and other properties to parts of objects that are hidden from view on the build tray display, you can temporarily turn off the display of some objects. To prevent the display of objects: 1. Right click an object, either on the build tray or in the model tree. 2. From the menu that opens, select one of the following options • Hide, to cause the selected object to disappear.
Using Objet Studio Positioning Objects on the Build Tray To produce models efficiently and with the required finish, it is important to carefully position objects on the build tray. Objet Studio supports the automatic positioning of objects. However, you should check to make sure that the objects are orientated logically for your needs, according to the considerations explained in Model Orientation on page 5 29.
Objet1000 - Connex 2 User Guide Automatic Placement After placing several objects on the build tray, you can let Objet Studio arrange them on the tray for printing. This ensures that the objects are positioned properly, and that they will be printed in the shortest time and with a minimum of material. To automatically arrange objects on the build tray: On the Tray Settings ribbon, click . or From the Tools menu, select Automatic Placement.
Using Objet Studio Figure 5-34: 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. • The physical characteristics of each type of model material you use can affect the positioning of objects on the build tray. Therefore, select the material before running Automatic Placement.
Objet1000 - Connex 2 User Guide 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.
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.
Objet1000 - Connex 2 User Guide Valid Object Placement You can ensure that models do not overlap when you position them on the build tray, and that they do not extend beyond the tray. To ensure valid object placement: 1. From the Tools menu, select Constraints Settings. Figure 5-36: Constraints Settings dialog box 2. Select Dynamic check to identify: • • • • invalid object placement while placing objectsOn Drop selected. invalid object placement after moving objectsWhile Drag selected.
Using Objet Studio Using a Grid to Position Objects Displaying a grid on the image of the build tray can be useful when positioning objects. To use the grid features, select the following menu options. Menu Option Result Tools > Grid Displays a grid on the build tray. Tools > Snap to grid When moving the object, it aligns with the nearest grid line. Tools > Options > Grid Enables you to change the grid origin (X and Y axis meeting point) and appearance.
Objet1000 - Connex 2 User Guide 3D files contain an 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.
Using Objet Studio Setting Model Dimensions You can change an objects dimensions by changing its size on the X , Y , and Z axes, from the Dimensions group on the Model Settings ribbon. Figure 5-41: Dimensions on the Model Settings ribbon • If Uniform Scale is enabled, changing the objects dimension on one axis affects the other dimensions, proportionately. • After changing a measurement, press Enter or click in another filed in the Dimensions group.
Objet1000 - Connex 2 User Guide 3. If you click on a corner of the frame, the cursor changes to indicate that the object can be rotated. Figure 5-43: Manually rotating an object 4. Manipulate the object with the arrow keys or with the mouse. Using the Transform You can make precise changes to an object by changing the properties in the Dialog Box Transform dialog box. To access the Transform dialog box (when an object is selected): on the Model Toolbar or on the Model Settings ribbon.
Using Objet Studio Changing an Object’s Orientation There are several methods for changing the orientation of objects on the build tray. To rotate an object: Select the object and use the Object menu options (see also Repositioning Objects on page 5 34). To re-align an object’s plane: 1. On the Tray Settings or Model Settings ribbon a. Click the icon in the Selection group: or . b.

Using Objet Studio In the model tree, the objects now appear as children of a parent (assembly). Figure 5-47: Assembly in the model tree After creating an assembly, you can save it as an objdf file, for re use. (Saving the assembly is not necessary for manipulating and printing it). To save an assembly: 1. Select the assembly (either on the build tray or in the model tree). 2. From the Objet Studio Commands, select Save As. 3.
Objet1000 - Connex 2 User Guide Display Options Viewing Objects From the View menu, you can change the way objects are displayed. The default method for displaying models on the build tray is as solid (shaded) objects. Figure 5-49: Tray and model displayed in Shaded view The other display options are WireFrame and Points. To display the build tray in WireFrame view: From the View menu, select WireFrame.
Using Objet Studio To display objects as boxes, showing their maximum dimensions instead of their shape: From the View menu, select Display Bounding Box. Figure 5-51: Model displayed with bounding box To display the area around objects needed for support material (to produce a matte finish): From the View menu, select Display Thickening Box. Figure 5-52: Model displayed with thickening box To display the maximum build height: From the View menu, select Display Tray 3D Box.
Objet1000 - Connex 2 User Guide Screen Layout Objet Studio automatically adjusts the default screen layout to display the optimum views of the build tray and the model tree. You can view models from different perspectives by changing the screen layout. To change the screen layout: On the View flyout toolbar, select Single View, or 4 Views. Figure 5-54: Screen layout icons Single View 4 Views is the default screen layout. displays perspective, top, front and right views.
Using Objet Studio Tray Perspective The default perspective of the build tray is isometric. You can change the perspective of the active window with one of ten options. To change the perspective of the build tray in the active window: 1. On the Tray Settings ribbon, open the Perspective flyout toolbar. Figure 5-57: Perspective flyout toolbar 2. Click the icon that represents the desired perspective.
Objet1000 - Connex 2 User Guide To manually rotate the tray: Press Alt and press the mouse wheel while moving the mouse. Figure 5-59: Tray after rotating it upside-down Setting Object Colors The color of objects on the build tray can indicate how they are printed. Objet Studio enables you to choose the color display so that you can easily see the material, surface and coating of objects.
Using Objet Studio Loading Large Files Very large stl files can be slow to load and may be difficult to manipulate easily on the build tray. If this is the case, you can display just an image of the object on the build tray without loading the entire file. The stl file itself is not changed, and the complete file is sent to the printer. To display an image of stl files when you place objects on the build tray: 1. From the Tools menu, select Options, and display the Settings tab.
Objet1000 - Connex 2 User Guide To use polygon reduction: 1. From the Tools menu, select Options. or In the Objet Studio Commands Menu, click Options. 2.

Enter the percentage of total polygons to display. When you click Apply, the display changes. Note: The setting affects the static display (when the object is not being moved). 6.
Using Objet Studio Object display options The display format affects how quickly objects display. For example, if you select Bounding Box, objects display faster than they do when you select Entire Object. You can choose display formats for objects when they are stationary (static view) and for when you are dragging them (changing view). To select the object display preference while changing view, and in static view: 1.
Objet1000 - Connex 2 User Guide Handling Completed Trays After you have properly placed all objects on the build tray, you save the tray as an objtf file, which is sent to the 3D printer for production. But before saving the tray, you can check that there would be no problem producing it. You can also calculate how much material would be consumed during production and how much time this would take.
Using Objet Studio Production Estimates Objet Studio enables you to calculate the time and material resources needed for producing trays before sending them to the printer. The time it 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 computers specifications.
Objet1000 - Connex 2 User Guide 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.
Using Objet Studio Printing the Tray File When a tray is ready to be printed, it is placed in the Jobs Queue. When the job reaches the head of the queue, Objet Studio pre processes the tray file to create slices, and feeds them to the 3 D printer. To send the tray to the print queue: 1. On the Tray Settings ribbon, Build Process group, click .
Objet1000 - Connex 2 User Guide • 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.
Using Objet Studio Model Material Substitution Figure 5-72: Model Material Substitution dialog box If you allow the use of substitute model materials, the printer will use different materials whose characteristics (strength, flexibility, etc.) are similar to those of the material you assigned to the object when designing the build trayunder the following conditions: • The material you assigned is not installed in the printer at the time of printing.
Objet1000 - Connex 2 User Guide 4. Click Build. If the build tray file has not been saved, the Save As dialog box opens for you to save it now. Objet Studio checks if there is a problem with the positioning of objects on the tray. If so, the affected objects are displayed with special colors (see Tray Validation on page 47), and a warning message appears. Figure 5-73: Tray validation warning message • To cancel the Build command so you can correct the problem, click No.
Using Objet Studio Applying Additional Objet Studio Features Dividing Objects You can use the Split Object feature to produce objects larger than the tray area by dividing the model into separate parts. With this feature, you produce only a specific section of a model. To split an object: 1. Select the object. 2. From the Object menu, select Split. 3.

Objet1000 - Connex 2 User Guide Choosing the Support Strength When producing models, support material fills some hollow and empty sections (see Model Orientation on page 5 29). Objet Studio allows you to 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.
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.
Objet1000 - Connex 2 User Guide Displaying the Cross Section of Objects The Section feature enables you to view the interior of an object by slicing it on any axis. You can then manipulate the object to inspect the interior from different angles. This may be important for deciding on the type of support necessary when producing the model (see Choosing the Support Strength on page 5 55).
