3D printing is something that only very few people and companies have ever used, but there is no question as to the uses that the technology can have, from coloring/painting 3D objects to actually creating them.
Unfortunately, 3D printing is still an expensive and largely inaccessible technology, and is going to stay that way for a long time, unless the Eventorbot project gets off the ground.
Hosted by Kickstarter, it is an open-source 3D printer that Duy Dang has built, with fewer parts and, by extension, less difficulty of assembly.
In fact, 80% of the Eventorbot parts are printable (basically everything except the solid steel frame), so the first one you build can be used to make more for even less money.
The link to downloading the plans of the printer and tutorial and demo videos are available on the same page as the project itself. Go here
