This is the first time an actual 3D printer has been offered to the public; well actually, it is not quite ready to be offered yet, as it is currently in the fund raising stage at Kick-starter. However, they are talking about an early 2012 delivery for the first models, which sounds good! The 3D printer will be able to make all sorts of objects from plastic once fully operational.
Here is some of the text from the site that explains just what the idea behind this printer is;
I designed the Printrbot to be the simplest 3D printer yet. There are some great kits out there – the Makerbot, the Ultimaker, the Prusa Mendel, and others – but none as small and simple as the Printrbot. This all-in-one 3D printer kit can be assembled and printing in a couple of hours. Other kits will not only take you many more hours to build, they will also have hundreds more parts, and they will cost more. My design also does away with the finicky calibration and adjustment from which most 3D printers suffer. This is the printer a kid could put together. We assemble the electronics, we assemble the hotend, and we put the connectors on all the motors and components… no soldering required!
