Free and open source under the AGPL. Some cloud features expect a Bambu Lab account, but local printing does not.

• Built-in calibration tests for temperature, flow, retraction and pressure advance
• Scarf seams and wall spacing control for visibly better surfaces
• Profiles for Bambu, Prusa, Voron, RatRig and Creality machines
• Windows, macOS, Linux AppImage and Flatpak builds including ARM64

• Multi-material painting with transition filament flushed into infill rather than a purge tower
• Remote control and monitoring of a networked printer from the slicer
• Reads STEP files and emits arc moves (G2/G3), plus assembly and explosion views
• Multiple build plate management, auto-arrange and auto-orient

• More settings exposed than a first-time printer owner needs
• Copycat sites such as orca-slicer.com push unsafe downloads, so use orcaslicer.com
• Releases move fast and occasionally regress a printer profile

• Built around Bambu Lab hardware; other printers need profiles set up by hand
• Cloud features push you towards a Bambu account
• Linux support is AppImages for Ubuntu and Fedora plus a Flatpak, not native packages
• Heavier and busier than PrusaSlicer, which it forked from

• orcaslicer.com
• github.com/SoftFever/OrcaSlicer

• github.com/bambulab/BambuStudio
