Houdini Digital Fabrication — procedural G-code for Bambu

An open-source HDA toolkit for importing, designing, checking, and rebuilding Bambu toolpaths directly inside Houdini.

Methods: Houdini · Digital fabrication · G-code · Python · HDA

01 · notes

The fab:: tools turn G-code into editable Houdini geometry while preserving layers, extrusion, feed rate, travel moves, and source data. The path can then be modified, validated, and packed back into a printer-readable .gcode.3mf.

Other HDAs generate 2D and 3D extrusion paths from curves, with bed-bound and safety checks keeping procedural experiments connected to the physical printer.
