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.2017http://zaguan.unizar.es/record/7069610.1016/j.promfg.2017.09.145http://zaguan.unizar.es/record/70696oai:zaguan.unizar.es:70696Procedia Manufacturing 13 (2017), 864-871by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
