A Program to Convert from Wavefront (OBJ) to Stereo Lithography (STL) Formats


This is a very simple program that converts between the main export format of 3D Surface modellers - the Wavefront Object (OBJ) format - and permits it to be imported into many 3D Printers. This program bridges the gap between the two. It is a simple program that reads a simple facet based OBJ file and translates it to an ASCII or binary STL file. All texture mapping and vertex normals are lost in the translation because the STL format is too simple to hold this data.

The program is a 32 bit Windows program, and is known to run on Windows 7 (32 & 64 bit versions) and Win 10 (64 bit). It may run under WINE on Linux. It should work in any 32 bit windows operating system. The program is a single file .exe file and executes in any directory you extract the file to. It writes no files other than the .stl file.
