3D printer for rapid prototyping.

While I wait for the new electronic parts to arrive, I found a printer that prints 3D plastic objects. The most amazing thing is that extremely cheap compared to the price of industrial printers for rapid prototyping. This type of printer is more like a desktop printer. Some 3D printers, are open source community projects like the RepRap project. The following video shows how the RepRap 3D printer works.

The parts for the quadcopter were made by hand and they look rough. But with a 3D printer I can quickly make the parts and reduce the weight by replacing metal parts with plastic. I can also do more aerodynamic parts. To make the parts, it is necessary first to model the parts in a 3D software like Blender, Wings 3D or OpenSCAD and then save in a format that can be read by the 3D printer, usually in a stereolithography file (stl). Now I have to find someone who has a 3D printer near where I live that can print the parts, but first I have to model each part of the quadcopter in 3D. But it would be interesting to make a kit that people could then print and assemble using a 3D printer.
