Source Files

Objet30 printing systems produce three-dimensional models designed with
most CAD tools and some other 3D applications.
Objet Studio supports these file formats:
•
•
GrabCAD Print supports STL, VRML, OBJ and 3MF files. In addition,
GrabCAD Print supports native CAD formats from these programs: Creo,
SOLIDWORKS, NX, CATIA and Inventor. To see the complete list of file
formats supported by GrabCAD Print, go to:
formats.
Objet30 systems feature the capability of producing different types of model
files simultaneously.

STL Files

STL is short for STereoLithography or Standard Triangulation Language. This
language views any object as a collection of surfaces, and describes each
surface of the object as a collection of triangles.
For example, a square can be described as two triangles; a cube (six squares)
as 12 triangles. Curved surfaces need more triangles to describe them. The
higher the tolerance (for smooth surfaces), the more triangles are needed.
Most CAD software can export STL files. Objet Studio/GrabCAD Print opens
these files for printing models on the printer.

SLC Files

SLC is short for Stereo-Lithography Contour. SLC files describe two-
dimensional contours of the three-dimensional models. These contour lines
are polylines.
SLC files are ASCII (text) files that save models as a series of slices. This
means that models based on SLC files cannot be orientated; only their scale
(size) and position on the build tray can be controlled. For this reason, the
model's orientation must be suitable for production before it is saved as an
SLC file. Because of the nature of SLC files, the appearance of models in Objet
Studio may be different than the solid-object images displayed from STL files.
