About the 3D Print Preview User Interface
The 3D Print tab provides a preview of the models you are about to print. The 3D Print tab consists of commands and shortcut menus. To access the 3D Print tab, from the Tray tab, click Preview 3D Printing.
Commands
• Tessellate Models—Sets the parameters of the STL file.
• Clipping—Enables clipping the view, using the 3D dragger.
• Display Support Material
◦ Materialise build processor—Displays the actual support material that is generated using a Materialise build processor.
◦ All other printers—Displays the estimation of the support materials. The estimation is generated by projecting the surface of the parts onto the tray.
• View > Draft Angle—Sets the minimal angle that the system automatically adds support material to the model. This is a visual representation and does not affect the way the model is printed.
• Save Printing Job—Saves a file that contains 3D printing data that you can send to a printer later. Available when you connect through a Materialise build processor.
• Print—Starts the 3D printing process.
• Return to Tray—Closes the tab and reopens the Tray tab.
