Many times we are limited when designing complex models, but thanks to the existence of repositories of 3D models can be found these already designed. In this software the user can vary all the parameters of impression and must verify the model looking for open zones between faces or surfaces, since if they exist, they will cause errors in the form of voids or filament detachments by the piece. Once the STL of the desired model has been selected, it must be entered in a rolling software ( Cura, Simplif圓D.) to generate the GCode, code used by the 3D printer for manufacturing. STL files are most commonly used to make 3D models, ahead of OBJ files, by the vast majority of the 3D printing community.
