[comp.graphics] Stereo-Lithography File Format

ganter@milton.u.washington.edu (M. Ganter) (06/26/91)

I'm looking for information about Stereo-Lithography .STL files.
.STL files are an interchange format used by Stereo-Lithography
vendors.  It is suppose to be a "standard."  I've been contacting
the vendors and surprizingly they have been little help!?  Can anyone
in comp.graphics netland point me to documents on .STL and/or PD
source code for interchange code.

My application is development of a backend to a solid modeling system
to produce mold patterns.

Your best bet is to try 

3D Systems Inc.
26081 Avenue Hall
Valencia, CA 91355

(805) 295-5600 Fax: (805) 257-1200

This is the company that originated the first STL machine and defined the
format for STL files.

I am interested in the same. I am also working for an application for
the stereolithography process. So any pointers/help pass them my way too.
