Preparing Files for Use with PolyJet 3D Printing Systems
Before printing design files with the Objet350 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.)
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
do this in GrabCAD Print or in a third-party STL-repair application (such as

Converting CAD Files to WRL Format (VRML)
You can save CAD designs as VRML files (WRL format) for printing. If you
assign RGB values to shells (parts) in the CAD design and then import the VRML
file in Objet Studio, Digital Materials that provide the best color match are
automatically assigned to the shells. The printer fabricates these Digital Materials
from the base materials loaded in the printer.
Objet Studio supports VRML 2 files (also known as VRML97 files).

❒ Total Quality—approximately 0.01 mm (deviation tolerance / linear-
dimension tolerance)
❒ Detail Quality—approximately 5° (angle tolerance)
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.

option is recommended.)
