Stratasys J3 Series User Guide

Source Files

Stratasys J3 Series printing systems produce 3D prints designed with most
CAD tools and some other 3D applications.
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.
J3 Series systems feature the capability of producing different types of 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. GrabCAD Print opens these files for
printing on the printer.

VRML Files

VRML is a 3D file format which includes color and texture information. VRML
provides the ability to apply different colors and textures to a 3D print while
designing in a CAD program. No further color assignment is needed in
GrabCAD Print.
When you create a VRML file in most CAD programs, two files are created: a
wrl file, containing the 3D print's geometric information, including texture, and a
picture file (bmp, png, jpg, or tiff), containing the 3D print's color information.
Before placing a VRML file on the build tray, make sure that the VRML file and
its corresponding picture file are in the same folder.

Slicing Resolution

The slicing resolution is as follows:
X = 300 DPI
Y = 300 DPI
Z = 1354 DPI (18.75µ layer thickness)
