Attack of the 3D Printer Bots

From the Hot Hardware:

One of the big attractions, a technology area that has experienced explosive growth recently, is the land of 3D Printing. MakerBot took the open source RepRap 3D replicator project mainstream back in 2009 with the release of the Cup Cake CNC machine, then came the Thing-o-Matic and then a little bot called Replicator. With each iteration, improvements in process and technology are bringing better, more capable 3D printers to market, from MakerBot's new Replicator 2, to new players in the field like Solidoodle, Up!3D, Ultimaker, and Tinkerines. MakerBot's Replicator 2 is a proprietary design, a first for the company and a first in a field that historically established its roots in a passionate, collaborative open source community model. Most commercially available 3D printers today are delivered unassembled and as such, modifications and improvements can be introduced easily, spurring new designs, features and capabilities. To watch a 3D printer in action is like witnessing art, science and engineering all working together in glorious unison. And regardless of your geek status or lack thereof, the objects you can design and build with one of these machines will blow you away.
