GTS to STL Conversion: FAQ

What are GTS files?

The GTS format is associated with the Gerber group, which is a collection of over 20 extensions used as standards in the production of printed circuit boards (PCB). Gerber images describe different data connected to such boards and can be created using Eagle, Orcad or Protel software. GTS images describe the top solder mask and can serve as input files for photoplotting machines that produce PCBs.

What are STL files?

STL is the proprietary format for a computer-aided design (CAD) program developed by 3D Systems.
