3D print directly from FreeCAD - tessellate, slice and print in one click

The SimplyPrint addon for FreeCAD bridges the gap between parametric CAD and 3D printing. Model in FreeCAD, then send your work straight to your printer in a single click - no separate mesh export step, no juggling files between programs.

The addon adds a context-aware SimplyPrint dock panel that adapts to the workbench you're in - pick solids in Part or Part Design, send meshes as-is from the Mesh workbench, or push a whole Assembly as one file. It also installs a dedicated SimplyPrint workbench with a toolbar and menu for one-click access from anywhere. Pick STL, 3MF or OBJ, choose mesh quality, hit Send to SimplyPrint, and SimplyPrint opens in your browser with the model loaded - ready to slice, queue, or print.

Getting started

The SimplyPrint dock panel docks on the right of the FreeCAD window (available in every workbench). Click Log In the first time - a browser tab opens, you approve the request, and you're set for future sessions.

Open or model something with solids or meshes - the panel shows the objects it found, the mesh-quality options for solids, and the real bounding box and volume. Choose a format and mesh quality, tick the objects to send, and click Send to SimplyPrint. Your browser opens SimplyPrint with the file loaded, ready to slice, queue, or print on one or more printers.

• Export STL, 3MF or OBJ directly from FreeCAD to SimplyPrint

• Context-aware panel - works in Part, Part Design, Mesh and Assembly workbenches
• Multi-object or one-file-per-object, with chunked uploads for big assemblies
• Works on Windows, macOS and Linux (native and flatpak)
