Construcción de una impresora 3D para la elaboración de piezas mediante el método de extrusión.

Abstract

3D printing nowadays is considered one of the most revolutionary technologies from XXI century. Doctors, engineers, craft lovers and small business owners have used 3D printing that allows to transform a virtual idea into a physical object. Now, we are able to appreciate how this technology is revolutionizing the way of seeing the world and of doing things in a more optimal and automatic way. The 3D printer allows you to make 3D designs replicas, create volumetric pieces or models from a design made by computer or software. Its structure is mostly acrylic; functionally, it consists of five engines step by step for its Cartesian motion along with bars and rails, a control board, 12 V power supply that is going to power both the control board and all the engines. To start up the 3D printer, we use a board based on an ATMEL microcontroller. The machine gets instructions from the computer (shaped like G codes) by means of a USB cable. In addition, through its own software turns that instructions into electrical signals for the engines starting placed in each of the X, Y, Z axe s. At the same time and in the same way, the extruder engine is active and, through it, the PLA or ABS is inserted at 190ºC to 235ºC.
