Hey guys, I can't remember who it was on this forum that uses a 3D printer for making tooling - perhaps there are a few people using this technology. The tooling I'm talking about are along the lines of very basic shapes.
As 3D printers progress all the time, what sort of plastics are used? how hard are they? are the plastics used structurally sound? are we there yet?
All that said, what is the software used to create the files? Open Source preferably.
