I'm one of the first professionnals to offer a service based on REPRAP 3D-Printers.
Read all about 3D Printing on Wikipedia : https://en.wikipedia.org/wiki/Fused_deposition_modeling
Please use the contact form to ask me anything about this service or send me an e-mail.
All my "tool-chain" (the programs I'm using) is Open-Source : Debian stable, Blender, Printrun, Slic3r, MeshLab, OpenSCAD.
The plastic I'm using is not real plastic. It's better. It's BIO-PLASTIC from Corn and so it's organic like wood, and bio-degradable. The exact name is PLA for PolyLactic-Acid. So for that reason, you must protect the objects from temperatures above 60°C (in the car on summer...) and from humidity if the objects are not painted or protected from outside environment.
