Printing mistakes are more common than we think, and after a lot of work in modeling within the CAD software and preparing for printing with the Slicer3D or laminator it is a shame that we did not manage to print what we had designed. But ... does this have a remedy? How can I repair STL files? The answer is yes!. There are 3D software for the repair of 3D models that will avoid any problem when printing. These platforms allow you to evaluate your model and correct any problems before sending your model to the 3D printer.
We present these 5 free programs, ideal for both professionals and fans of 3D printing.
