I read an article on some online journal. Last summer, they had this event in town and one 3D printing lab put up a workshop to showcase a few different printers. I was fascinated to see not only plastic but also metal being printed. They had a prosthetic jaw up for display and some surprisingly big vases being printed slowly but surely. Some visitors were modelling smaller prints. Anyways, I asked a few questions and left the shop impressed. I tried to find more information and invested in a Peachy Printer Kickstarter to have at least something to play with myself.
