Slic3r is free software 3D slicing engine for 3D printers. It generates G-code from 3D CAD files (STL or OBJ). Once finished, an appropriate G-code file for the production of the 3D modeled part, or object is sent to the 3D printer for the manufacturing of a physical object.{{cite web|title=slic3r - G-code generator for 3D printers|url=http://slic3r.org|website=slic3r.org|accessdate=19 April 2015}}{{cite web|last1=Weinhoffer|first1=Eric|title=Getting Started With Slic3r|url=http://makezine.com/projects/getting-started-with-slic3r/|website=makezine.com|publisher=Maker Media, Inc.|accessdate=19 April 2015}} As of 2013, about half of the 3D printers tested by Make Magazine supported Slic3r.{{cite web|last1=Abella|first1=John|title=Know Your Slicing and Control Software for 3D Printers|url=http://makezine.com/magazine/guide-to-3d-printing-2014/know-your-slicing-and-control-software-for-3d-printers/|website=makezine.com|publisher=Maker Media, Inc.|accessdate=19 April 2015|date=19 November 2013|url-status=bot: unknown|archiveurl=https://web.archive.org/web/20140325080822/http://makezine.com/magazine/guide-to-3d-printing-2014/know-your-slicing-and-control-software-for-3d-printers/|archivedate=25 March 2014}},
