Features

Helio Additive Update

This beta upgrades the Helio integration with major performance improvements, clearer results and guidance, expanded compatibility handling, and improved reliability of workflows.

  • Product & Pricing updates (Alpha → Beta):
  • Helio moves from Alpha to Beta with simplified pricing and practically unlimited Assess/Enhance under fair use ↗. The quota/token system has been deprecated.
  • 2-week free trial with full access for new users.
  • Product naming is now clearer:
  • Assess (formerly Simulation): predict where a print may fail before you print.
  • Enhance (formerly Optimization): autofix with new speeds; automatically optimizes for speed/strength/reliability/surface gloss.
  • Improved activation flow.
  • Performance Improvements: Helio now runs with GPU acceleration for both Assess and Enhance, runtimes are reduced compared to previous versions (up to ~5× faster in supported scenarios).
  • Compatibility Handling & Safeguards:
  • Multi-material detection: Jobs containing multiple materials are now explicitly detected, with guidance provided to help users proceed safely.
  • Unsupported material handling: When an unsupported material is detected, users are prompted to:
  • Select reference material for simulation, or
  • Switch to a supported material profile. Silent mismatches are no longer allowed.
  • Improved matching for custom materials and printers:
  • Token-based fuzzy matching is used to identify the closest supported profiles.
  • Material-type fallbacks and confirmation prompts have been added.

  • Clearer and More Actionable Results: Assess results now more clearly explain why an issue is likely to occur, and which parameters or settings contribute to the risk.
  • Fix suggestions are easier to locate and follow.
  • The printability report has been refined to reduce ambiguity.
  • Assessment guidance is more directly tied to concrete outcomes, such as improving reliability, reducing failure risk and increasing print speed.

image

  • Added Helio History:
  • View up to the last 10 Assess and Enhance runs.
  • Revisit previous results and download generated G-code for comparison.
  • Recent results can be recovered in case of network interruptions.

  • Reliability Improvements & Bug Fixes:
  • Improved error detection during G-code polling.
  • Backend error messages are now surfaced directly in failure dialogs, providing clearer diagnostics.
📌 Availability & Limitations:
- Helio is available on all Bambu Lab printers except H2C, based on current support status.
- For supported printers and materials, see

wiki.helioadditive.com/en/supportedprinters ↗ for more details.

Bug fixed

  1. Fixed an issue where enabling the prime tower outer-wall gap（"Process"-"Prime Tower"-"Skip points"） could cause missing outer walls in some scenarios.
  2. Fixed a conflict issue related to the user program under the web directory, thanks to @Bambu-Pomfret .
  3. Beta update notification was enabled by default since this beta, which can be disabled in Preferences.
  4. Fixed an issue where the top surface flow ratio in object settings could reset after re-selecting the object. (#9563 ↗)
