From their website:
All our products and projects are produced with 3D printing technologies. First we make a CAD file in a 3D software, such as Studio Max, Maya, Solidworks or Cinema 4D. We then upload the file to a 3D printer and finally unpack the 3D printer and take the product out. It pretty much works like you would be printing a normal Microsoft Word document out of your home 2D printer, but now you can just “print” real stuff in a whole range of different materials such as plastics, metals, rubbers and ceramic materials.
