Changelog 2026

← Back to All Changelogs

  • Bambu H2C printer support: Added full support for the Bambu H2C printer
  • Enhanced surface gloss feature: When users select “Enhance Surface Gloss”, the optimizer applies this value to outer walls for materials that support shiny/matte finishes.
  • Fan optimization ramp-up handling: Improved fan speed optimization to properly handle transitions between optimizable and non-optimizable partitions, including reading and setting ramp-up times.
  • Improved calibration for Polymaker Fiberon materials: Improved simulations & optimizations using Polymaker Fiberon materials on H2S and P2S printers.
  • Simulation results resolution controls: Exposed controls in Dragon configuration for adjusting the length and density of exported temperature data (not in standard permissions)
  • Free optimization grants: Fixed issue where free add-on optimizations weren’t granted immediately.
  • Some printer/materials not showing: Fixed a problem were some users were not able to see all printers & materials.
  • Feature flag exposure: Fixed dashboard UI to correctly display feature flags (bridge speed smoothing, optimize above bridge, fan speed optimization)
  • PAT linking dialogs: Improved store information handling to show appropriate dialogs for new users, returning users, and account re-linking scenarios
  • Improved suggested fixes from simulations
  • Add translations for print priorities
  • Fixed a few edge cases regarding assigning of free trials
  • New no-cap commercial and non-commercia l subscription plans
  • New pricing display
  • General reliability & usability improvements regarding payment processing
  • Added restrictionsV2 to GcodeV2, which provides localized descriptions (based on ACCEPT-LANGUAGE headers) as-well as enum values
  • Support for querying print priority options, and passing that as an option when running optimizations, with the current ability to choose; speed & strength, preserve surface finish and enhance surface gloss.
  • Updated the GcodeStatus enum to also add RESTRICTED. This differentiates from READY and ERROR such that there were no errors produced, we will restrict it from being used in simulations and optimizations due to either the file size is too large or total weight of the object too much.
  • Support handling M104 O-80 A and M140 D55 commands from BambuStudio G-Codes.
  • Fixed bugs relating to searching/filtering printers & materials
  • Added support for multicolour print optimisations. This includes:
    • AMS multicolour prints
    • Multicolour prints with layer-level post-slicing modifiers (e.g., Hueforge prints)
  • Added support for Bambu P2S and H2S. For a full list of supported printers and materials, see our Wiki.
  • Updated names for 3D-Fuel Pro PCTG in our database to match the latest configuration files from 3D-Fuel, profiles here
  • Support simulation and optimisation for Creality G-Codes
  • Setup status.helioadditive.com for an overview of API availability and health.helioadditive.com for an overview of the health of our invdividual services. These can be used to see any interuptions in our services.
  • Support improved errors from inability to parse G-Codes: we now also return the line number that caused us to fail parsing. See PrintInfo for detailed information.
  • Reduce Dragon simulation & optimization runtimes by improving handling of assets
  • Support an interactive GraphQL client which can be used to explore/build queries against our API
  • Added extra print information returned from simulations, allowing users to see detailed outcomes, the overall temperature profile, caveats, and suggested fixes.See PrintInfo and for details.
  • 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.
  • Provided fixes for bugs that were impacting Dashboard speed slowdown
  • General internal & API bug fixes
