The short version

  • Only Bambu Studio has a free tier, so it costs nothing to try first.
  • Each has a real cost: Altium 365 the 1,990 US dollar Altium Develop entry price is capped at five authors in total, so a growing team hits a forced migration to Agile Teams with unpublished pricing exactly when headcount is rising.; Bambu Studio profiles and tuning are aimed at Bambu Lab machines, so using it as a general slicer for other printers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.
  • They diverge on capability: Altium 365 covers Shared workspace, Bambu Studio covers Multi-material slicing.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Altium 365

  • A hardware startup where two engineers draw boards but eight people need to review them, avoiding eight CAD seatsnot Bambu Studio
  • A team handing fabrication and assembly data to a contract manufacturer as a versioned release rather than a zip of Gerbersnot Bambu Studio
  • A company running board and enclosure design in parallel and needing bidirectional geometry exchange with mechanical CADnot Bambu Studio
  • A buyer checking component lifecycle and availability against the live BOM before a design is frozennot Bambu Studio

Bambu Studio

  • Running a small farm of Bambu Lab printers where multi-colour AMS jobs need per-object material assignmentnot Altium 365
  • A design team that needs to check printability and support strategy before committing a part to a printnot Altium 365
  • Prototyping in a workshop where paying per seat for a slicer cannot be justifiednot Altium 365
  • Reusing PrusaSlicer knowledge and profile conventions on Bambu hardware without relearning a slicernot Altium 365

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Altium 365

  • The 1,990 US dollar Altium Develop entry price is capped at five authors in total, so a growing team hits a forced migration to Agile Teams with unpublished pricing exactly when headcount is rising.
  • Add-on portals are expensive per seat; BOM Portal has been quoted at around 1,999 US dollars per user per year and MCAD CoDesigner at around 499, so the real cost of a working configuration is well above the headline.
  • It is tied to Altium Designer; there is no meaningful use of the platform for teams designing in KiCad, OrCAD or Allegro, which makes it a lock-in decision rather than a tooling one.
  • Renesas acquired Altium in 2024, and a semiconductor manufacturer owning the design tool used to select competing semiconductors is a conflict some buyers will want addressed in writing before uploading a library.
  • Repeated repackaging, from Altium 365 Standard and Pro tiers to Altium Develop and Agile Teams, has made renewal comparisons difficult and customers have found their previous tier no longer maps to anything on the price list.

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.

Answered from the vendors’ own pages

Altium 365: Is Altium 365 free with Altium Designer?

A workspace is included with a current subscription, but the higher tiers, extra authors and the add-on portals are chargeable. The unlimited non-author users are genuinely included.

Bambu Studio: Does Bambu Studio cost anything?

No. It is free with no paid tier. Bambu Lab monetises the printers and filament, not the slicer.

Altium 365: What does it cost?

Altium Develop starts at about 1,990 US dollars a year for one author plus a workspace, with extra authors at 995 US dollars each up to four more. Larger teams are quoted.

Bambu Studio: 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.

Altium 365: Who owns Altium now?

Renesas Electronics completed its acquisition of Altium in 2024. Altium 365 is therefore a Renesas-owned platform.

Bambu Studio: 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.

Altium 365: Can I keep design data on my own servers?

Yes, through the Enterprise on-premise workspace server, but that is a quoted product and most of the newer portal features assume the hosted platform.

Bambu Studio: 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.
