I have the habit of keeping an ear on the happennings in the Rapid Prototyping industry because SYCODE offers quite a few products for that industry. Today my attention was drawn to a company called Mcor Technologies which offers a 3D printer that creates models from office paper. Yes, normal A4/Letter sized paper. They call it Paper Rapid Prototyping wherein sheets of paper are glued together and then weeded to result in a 3D part. Literrally 3D printing on good old 2D paper!
The product is called Mcor Matrix and is priced at 18,900 EUR ($27,760) with an annual maintenance of 1,500 EUR ($2,200).
I guess people buying one of these will have no need for a paper shredder.
