Preparing Files for Use with PolyJet 3D Printing Systems

Before using design files with Stratasys 3D printing systems, make sure that
they are in a supported file format. (For an explanation of these file formats,
see "Source Files" on page 3-4.)
Converting
This procedure may vary slightly, depending on the CAD software used, but

the following instructions generally apply.
STL Format
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
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 in an STL-repair application (such as Magics™, by Materialise
before opening them in Objet Studio and producing the model.
For more information, search for "CAD to STL" on www.stratasys.com.
You can save CAD designs as VRML files (WRL format) for printing. If you

are automatically assigned to the shells. The printer fabricates these Digital

Objet Studio supports VRML 2 files (also known as VRML97 files).
Converting
When converting files to SLC format, it is recommended that you set a layer

Objet Studio, it is important that models are properly orientated before being
saved as SLC files. Considerations for suitable model orientation are explained
in "Manual Positioning" in Chapter 3 on page 5-33.

select *.STL.
❒ 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.
formats can be used in Objet Studio. However, binary files are smaller, so
this option is recommended.)
