Resumen: The paper developed presents a case study that allows students to learn an easy way to improve the accuracy of low cost 3D printers. The document detailed a methodology to achieve this goal. First, it is necessary to print an initial CAD design. A commercial scanner is calibrated and the pieces are scanned to obtain the different errors. Then, a program is generated to compensate the code numerical control of the printer. This fact allows students to print a new piece having less errors than before, which it involves improve the printer accuracy.
