Ireland-based Mcor Technologies has developed a 3D printer that prints uses paper. It is actually a 3D printer that uses paper as media. Mcor provides specialized software that renders 3D objects into "slices" suitable for sending to the printer. The software even identifies and models the necessary support structures used temporarily during printing. Standard paper sheets are glued together during the printing process to form the 3D structure, using a "patented selective adhesive system." The printer is 40 times less expensive than traditional 3D printers claims Mcor. The Mcor Matrix desk top modeler can produce ready to use, three dimensional models from standard A4/Letter paper. This cost effective model maker will enable students, designers, engineers and hobbyists create 3D models at 2D prices.

The Mcor Matrix is not cheap as the projected price is €15,000 - 18,900 (USD22,000 - 28,000). It is the media where the real cost saving is as the cost of the build material is less than 2 cents per cubic centimetre.
