This is my first 3D printer, called iAlonso Printr. It uses 3mm PLA plastic, it has 5 motors controlled by a computer; it can print 200mm x 180mm x 180mm objetcs (7.87 x 7.08 x 7.08 inches). The video below shows the first object that was printed.
I want to thank my father, Miguel Angel Alonso, for helping me to build the printer and giving me ideas to improve it. Thanks dad. And also to Santiago López for give me the first printer parts and solve many questions.
