3MF Export Plugin

Frequently Asked Questions

Why isn’t this in HueForge?

HueForge is built around modelling — geometry, color stacks, layer assignments. Slicer support is its own moving target: every slicer has a different 3MF dialect, every Orca fork inherits something slightly different, and new ones land all the time (Elegoo Slicer, Anycubic Slicer Next). 3MF Export is a third-party plugin developed by Additive Atom; keeping it separate lets it ship updates on its own cadence — new slicers, new printer profiles, new fixes — without waiting on a HueForge release.

What’s included in the purchase?

  • The plugin for all three platforms (Windows, macOS, Linux) — one download covers your machine.
  • All updates for two years from purchase, including:
    • New slicer support as it lands.
    • New printer profiles as they’re contributed.
    • Bug fixes.
  • All ten currently supported slicers.

What operating systems are supported?

Three: Windows, macOS, and Linux. One purchase covers all three — the release archive includes the build for each. The Linux build is validated on Ubuntu 22.04 with Qt 6.9 and should work on other modern glibc-based distros (Fedora, Arch, Debian, etc.); if yours doesn’t, let us know.

Does it work with the ColorDrop, FlatForge, and HugeForge plugins?

Yes. Whenever those plugins hand off meshes for export, the 3MF Export Plugin picks the right layout for your slicer — single plate with N volumes for FlatForge / ColorDrop / Split-by-Color, multi-plate for HugeForge tile mode.

Why do filament change layer numbers differ from Describe.txt?

Describe.txt lists layer numbers for filament changes without a Height Range Modifier (HRM) applied. The 3MF Export Plugin adds an HRM automatically — it prints the beginning of your HueForge model at a larger layer height to speed up the base. Your slicer’s layer numbers shift compared to Describe.txt as a result, but the filament changes still happen at the right Z heights.

  9. Orca Flashforge
  10. Creality Print

My printer isn’t bundled. Can I still use the plugin?

Yes — import a printer profile from any 3MF you’ve sliced in your slicer. The plugin reads the embedded profile, lets you select it in the dropdown, and uses it for all future exports until you delete it.

Will it work with my AMS / CFS / ACE / CANVAS / MMU / Tool Changer setup?

If your printer is single-extruder, the plugin emits M600 filament pauses at each filament change and no multiplexer. If your printer has an AMS / CFS / ACE / CANVAS / MMU / Tool Changer, the plugin emits filament-change G-code that drives the swap automatically. The slot count auto-fills from the printer profile; you can override the Printer Slots value in the dialog.

What’s the translucent slot at extruder 1?

It’s a #E6E6E64D translucent placeholder filament the plugin prepends so your model has a uniform white-balanced base layer regardless of your bed color. Clear it if you’d rather not use it — it’s just a slot, nothing’s wired to require it.

I found a bug / something doesn’t work right

Contact us. Include the plugin version, slicer version, and ideally the exported 3MF so we can reproduce.

Where do you get the bundled printer profiles from?

Each bundled profile started life as a real 3MF or config bundle exported from the target slicer, with HueForge-required overrides (layer height, filament colors, custom G-code) applied. If you have a profile for a printer we don’t bundle yet, import it via the getting started import profile steps.
