MCor developed an amazing 3D printer. The idea is simple enough and seems to work incredibly well. They use a water based ink with an inkjet printer to print on "both" sides and through normal paper. That's 2D. Then they feed the printed sheets to the 3D portion of their machine. It just laminates the sheets, one sheet at a time, each layer/sheet getting water based glue along the edge of the slice and in a grid pattern. Pressure is then applied (with a bit of heat I believe) before a tungsten cuter traces the slice. The lamination repeats until a block of laminated paper can be pulled out. Here comes the fun part for the kid in each of us : just break off the extra bits of laminated paper to magically reveal your finished part ! The part itself received more glue so it is solid !! They also came up with a flexible material for their printer. Instead of a rigid solid object, the result is flexible... Conor MacCormack and his brother started the design of this unique 3D printing approach about 10 years ago. Their MCor Iris printer is being used in production environment for a few years now. Conor seems to find the democatized (ie Maker / Open Hardware) movement as the way to go. Not certain if that means the concept of the MCor Iris is "Open" though. But, eh, I'm certain a few of "us" could come up with a nextgen (ie. "home") version. The MCor Iris is about 40k$ (!) to buy, about 700 lbs to park anywhere since it is "green". With todays low cost home inkjet printers and a Vslot OX like stacker/laminator, someone here should be able to bring that cost way way down ... Maybe adding a a new twist to make it even better ? What are your thoughts ?
