In Ecuador there is a technological culture limited of Rapid Prototyping, which is being exploited to the maximum in other countries, especially in manufacturing, optimizing resources and time. Therefore, we have seen the need to design and build a 3D printer machine that can get plastic prototypes quickly and at low cost. This paper describes the design and construction of a 3D printer that can produce physical models in three-dimensional from a virtual model designed in CAD software for the Laboratory CNC of the University of the Armed Forces ESPE Extension Latacunga. The process starts from a digitized model of the appearance that the object should be reproduced, using free software is programmed the best strategy to follow the injector for printing model, the material extruded plastic state shall be deposited in the mobile platform applied layer by layer until the object has taken its final form. The machine consists of four mechanisms or axes: X, Y, Z form a mobile platform more the extruder mechanism, which has the function of extruding a plastic filament through a smelter. Control is via PC with free software and hardware, it will transform a 3D model programming language G code, before being sent to the controller, ordering the actuators move in speed and position on schedule. Additionally installed a control system and wireless monitoring, dispensing the need for a permanently connected to the machine PC. The prototype implemented and yielded excellent results obtained accurately models  0.1 mm. and resistance depending on the type of polymer used. Therefore it is possible to design and build a 3D printer using free software for prototyping and low-cost plastic parts.
