Concept
I've built a RepRap 3D printer that can make useful physical objects, including many parts to make another 3D printer. With it, I've fabricated the parts for three more 3D printers. One of them is shared with others who also want to have a 3D printer. They can learn from operating my 3D printer and they can fabricate themselves another set of parts to and another one for a friend. This helps spread this creative and magical technology that allows you to turn your ideas into physical objects. Examples application are many, and include household, personalized and engineering items.

I've also donated a full set of parts to a public hobby space in Lisbon. They will use it to make more machines for spaces in other cities.

Furthermore I'd like to keep improving the technology, ease of use and lower the cost.
