Changelog

20th January 2026

✨ New Features and Improvements

Added support for multicolour print optimisations in Bambu Studio. This includes:
- AMS multicolour prints
- Multicolour prints with layer-level post-slicing modifiers (e.g., Hueforge prints)

You can now optimise these for faster prints and improved quality.

Added support for Bambu P2S and H2S. For a full list of supported printers and materials, see our Wiki.
Added support for a new G-code error format in the API for formatting issues to include error type and line number, now also visible in Bambu Studio for easier debugging.
Added a new status page providing key statistics on the availability of our services for clients and partners.
Added a simulation summary window in Bambu Studio to provide better insights into print outcomes. You can now see upfront whether a print is likely to succeed or fail, and how certain layers are performing. See our Bambu Studio guide for more information.

🐛 Bug Fixes

Fixed an issue where formatting errors in G-code were incorrectly reported as platform temperature errors.
Fixed a bug causing the 3 free optimisations quota for anonymous Bambu users not to update correctly in Bambu Studio.

15th December 2025

✨ New Features and Improvements

Introduced a 14-day trial period for new Bambu users with verified email addresses, giving unlimited optimizations during this period.
Improved error reporting for G-code format and value errors, specifying where and what the error was, making it easier for users to debug or report issues encountered during simulations and optimisation. For developers, refer to API documentation on error codes.
Added support for new materials in Bambu Studio: Bambu PAHT-CF and PolyLite-LW PLA. For full material compatibility, refer to our wiki here.

🐛 Bug Fixes

Fix documentation showing incorrect units for some inputs. For more information, refer to API documentation.

29th October 2025

✨ New features and improvements

🐛 Bug fixes

Fixed an issue where optimisation results were delayed when loading back into Bambu Studio, making optimisation times appear longer.
Ensure DateTime scalar from the API included a timezone offset in its ISO 8601 format.
Fixed an issue where optimisation quota updates were delayed in Bambu Studio after subscription activation

Fixed an issue where certain large-format printing G-codes were not parsed correctly or failed to parse.
Fixed an issue where free optimisations did not update correctly in Bambu Studio once new PAT was activated.
Fixed a bug reading certain properties of .ada3dp (Adaone) files.
