PrusaSlicer
PrusaSlicer: The upstream project Bambu Studio was forked from, fully open source with no proprietary networking layer
Bambu Studio
Free slicer for Bambu Lab 3D printers, funded entirely by hardware sales
As of 31 August 2026, Bambu Studio is free to use. A free, AGPL-licensed slicer forked from PrusaSlicer and tuned for Bambu Lab printers, including multi-material AMS handling. Softwr lists it under CAD. Bambu Studio is made by Bambu Lab, available on Windows, macOS, Linux.
Overview
What Bambu Studio does
Bambu Studio converts 3D models into printer instructions: it slices geometry, generates supports, assigns per-object and per-filament settings, previews toolpaths and sends jobs to the printer over the network or via SD card. It is a fork of PrusaSlicer, which is itself descended from Slic3r, so the underlying slicing engine and much of the settings vocabulary will be familiar to anyone who has used either. The Bambu-specific work is in multi-material handling for the Automatic Material System, per-object process settings, printer profiles tuned to the CoreXY hardware, and cloud print management. The money question has a plain answer: the software is free because Bambu Lab sells printers and filament. There is no paid tier, no seat count and no upsell inside the slicer. That also explains the design priorities. Bambu Studio is optimised for Bambu Lab machines and its profiles for other printers are thin, so it is not a general-purpose slicer in practice even though the code would allow it. The fact that should change a shortlist is a licensing dispute rather than a feature. Bambu Studio is AGPL-3.0 by inheritance from PrusaSlicer, but the networking component that talks to Bambu cloud and, since the authorisation control firmware, to the printer itself is a proprietary closed binary loaded at runtime. In 2026 the Software Freedom Conservancy publicly stated that Bambu Lab is violating the AGPLv3, following a cease-and-desist Bambu Lab sent to a developer of an OrcaSlicer fork that reimplemented printer networking. For a hobbyist this is an argument on the internet. For an organisation with an open-source compliance policy, or one that wants to script its own fleet control, it is a procurement issue.
What people use it for
- Running a small farm of Bambu Lab printers where multi-colour AMS jobs need per-object material assignment
- A design team that needs to check printability and support strategy before committing a part to a print
- Prototyping in a workshop where paying per seat for a slicer cannot be justified
- Reusing PrusaSlicer knowledge and profile conventions on Bambu hardware without relearning a slicer

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Bambu Studio.
- Profiles and tuning are aimed at Bambu Lab machines, so using it as a general slicer for other printers means building and maintaining your own profiles, which is exactly the work a slicer is meant to save.
- The networking component is a proprietary closed binary loaded at runtime, so you cannot audit, self-host or script printer communication the way the AGPL licence of the rest of the code would suggest.
- The Software Freedom Conservancy publicly stated in 2026 that Bambu Lab is violating the AGPLv3, and Bambu Lab has issued a cease-and-desist to a third-party fork developer, which is a live legal question for any organisation with an open-source compliance policy.
- Cloud features require a Bambu account and route job data through Bambu servers, which is a data governance problem for anyone printing commercially sensitive geometry.
- The software is free because the hardware is not, so there is no way to buy support or a maintenance commitment; if a release breaks your workflow your only recourse is the community forum and waiting.

Questions people ask
Each answer names the page it came from, so you can check it rather than take our word for it.
Does Bambu Studio cost anything?
No. It is free with no paid tier. Bambu Lab monetises the printers and filament, not the slicer.
Is it open source?
Mostly. The slicing application is AGPL-3.0 by inheritance from PrusaSlicer, but the networking plugin is proprietary and closed, and that combination is the subject of the Software Freedom Conservancy dispute.
Can I use it with a non-Bambu printer?
Technically yes, since it is a PrusaSlicer fork, but the shipped profiles target Bambu machines and you would be maintaining your own configuration.
Can I print without a Bambu cloud account?
Yes, over the local network in LAN mode. Cloud printing, remote monitoring and MakerWorld require an account.
