Blender

Blender is a free and open source 3D creation suite coordinated by the Blender Foundation and licensed under the GNU GPL, which allows use for any purpose including commercial and educational work. For 3D printing makers, the relevant part is the STL importer and exporter documented in the Blender 5.2 LTS Manual under File ‣ Import/Export ‣ Stl (.stl). The manual states the STL format is useful for importing and exporting files for CAD software and is commonly used for loading into 3D printing software. Modeling itself happens in Edit Mode, which edits meshes, curves, surfaces, metaballs, text objects and lattices. Version numbers and menu paths follow the current manual; later releases may change them.
