Unofficial planar-face tools for Bambu Studio — AGPL-3.0 fork.
Unofficial. An independent modification of Bambu Studio (AGPL-3.0). Not affiliated with, endorsed or supported by Bambu Lab. "Bambu Studio" and "Bambu Lab" are trademarks of their owners.
FaceTools adds direct, face-based mesh editing tools to the Prepare view, aimed at quick fixes of already-modelled STL/3MF parts without going back to CAD.
- Extrude / move planar faces as a new part, or union/subtract with the source, with live preview and numeric or drag distance.
- Point-defined profiles for extrusion.
- Position by point coincidence — snap one part's point onto another's.
- Cut and extend — cut a part at a face-defined plane and move/stretch one side (guide faces select the connected region to move).
- Native Cut from a face, Smart fill by angle, and support for faces of negative parts (cutters).
- Undo/Redo integration and unit tests for the geometry core (
tests/libslic3r/test_face_extrusion*.cpp).
- Prototype. It is a mesh-based tool, not a parametric CAD kernel: no BRep, no curved-surface editing, no shortening, no general "Move Face".
- GUI acceptance is only partial. Automated tests pass (162 test cases) and "Cut and extend" and the face-plane Cut were verified by hand on a real part, but the other manual scenarios (see docs/facetools/TEST_CHECKLIST.md) are not all verified. Expect bugs and always keep a backup of your project.
- Cut and extend moves one connected piece. Guides on two separate pieces are refused ("select one moving component"); run the tool once per piece.
- Known upstream issue: the stock Cut with a numeric plane coincident with an existing face (or within ~0.001 mm) can return a piece with open edges. Pick the plane from the face ("Use guide face as plane") or offset it by at least 0.01 mm.
- Printing to a cloud printer is not authorised for forks. Bambu restricts "Print" for unsigned third-party builds; sending files may work, but direct Print can fail. No attempt is made to bypass this. The proprietary Bambu network plugin is not included.
- macOS arm64 only so far; binaries (if provided) are ad-hoc signed, not notarized.
Follow the upstream build guide (https://github.com/bambulab/BambuStudio/wiki) and BuildMac.sh. Needs Homebrew zstd and imath among others. Releases, when available, list the exact source commit.
AGPL-3.0 — see LICENSE. This is a derivative work of Bambu Studio, PrusaSlicer and Slic3r; third-party licences stay with their code. Changes are listed in FACETOOLS_CHANGES.md. Source for any binary: the tagged commit of this repository.
Bambu Studio is a cutting-edge, feature-rich slicing software.
It contains project-based workflows, systematically optimized slicing algorithms, and an easy-to-use graphic interface, bringing users an incredibly smooth printing experience.
Prebuilt Windows, macOS 64-bit and Linux releases are available through the github releases page.
Bambu Studio is based on PrusaSlicer by Prusa Research, which is from Slic3r by Alessandro Ranellucci and the RepRap community.
See the wiki and the documentation directory for more information.
Key features are:
- Basic slicing features & GCode viewer
- Multiple plates management
- Remote control & monitoring
- Auto-arrange objects
- Auto-orient objects
- Hybrid/Tree/Normal support types, Customized support
- multi-material printing and rich painting tools
- multi-platform (Win/Mac/Linux) support
- Global/Object/Part level slicing parameters
Other major features are:
- Advanced cooling logic controlling fan speed and dynamic print speed
- Auto brim according to mechanical analysis
- Support arc path(G2/G3)
- Support STEP format
- Assembly & explosion view
- Flushing transition-filament into infill/object during filament change
Following platforms are currently supported to compile:
- Windows 64-bit, Compile Guide
- Mac 64-bit, Compile Guide
- Linux, Compile Guide
- currently we only provide linux appimages on github releases for Ubuntu/Fedora, and a flathub version can be used for all the linux platforms

By default, after installing Bambu Studio without the networking plugin, you can initiate printing through the SD card after slicing is completed.
