Once machines like that get around $100-200, that changes everything. Being able to download plans and build your own shoulder rig from scratch. Game changing...but it's not there yet.

Yeah...at least 20 years....assuming we all survive 2012. :P

A very interesting machine. However, people don't realize that you can get a used 3D pro Printer for a very reasonable price. I have a full size (about the size of a stove) 3D printer that I bought for $2K called a Zcorp 402. I've tested a bunch of different DIY materials and can build anything in roughly a 7" x 7" X 9" box. It uses a powder spreader method. You can sometimes find them on Ebay. They do usually need a fair amount of maintenance to get them up and running though. But not bad for 2K. They don't make the model anymore so people that don't know you can make your own spare disposable parts sell them cheap. All it uses is Plaster powder called Hydroperm and inkjets with distilled water and 20% ethyl alcohol. You then harden it with crazy glue. It builds layer by layer in the powder build side. If anyone wants more info you can hit me up. However most people think that you build it and its done. These things take a fair amount of post production to really get them nice and clean. Their patent is supposed to be up this year but I am sure that they will figure out some legal way to avoid that happening.

There are companies getting rid of them because they need tighter tolerances for their parts.
