Preparing Files for Use with PolyJet 3D Printing Systems

Before printing design files with the Objet30 printer, make sure that they are in
a file format supported by the applications you are using to send print jobs to
the printer—Objet Studio or GrabCAD Print. (See "Source Files" on page 3-4.)
You can print several models or parts at the same time, after arranging them
on the build tray in the file preparation software. The following are the
maximum dimensions for a single model printed on the Objet30 printer:
• With glossy finish—
• With matte finish—

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 drop-down list and select
3. Click Options and set the following parameters:
4. In the file format option, choose binary or ASCII. (Both binary and ASCII
5. Click OK or Save.
After converting the model files, it is recommended that you check them for
defects before opening them in Objet Studio and producing the model. You can

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.

this option is recommended.)
