3MF Export Plugin

Your first export

Once the plugin is installed and you have a HueForge project open, the end-to-end flow is:

1. Open the Export 3MF dialog

Menu bar → 3MF Export → Export 3MF. (You can also use File → Save Project As and tick Use 3MF Output in the side panel — same dialog, different entry point.)

2. Pick a slicer

The Slicer dropdown is the first decision. The plugin uses your choice to drive which 3MF dialect to write — Bambu/Orca-family, Prusa-family, or Anycubic Slicer Next have meaningfully different formats internally.

If you don’t see your slicer, you may need to import a printer profile first.

3. Pick a printer profile

The Printer Profile dropdown shows two kinds of entries:

  • Bundled profiles — for popular printers (Bambu, Elegoo, Anycubic, Prusa MK4, Snapmaker U1, etc.) the plugin ships ready-to-use profiles.
  • Imported profiles — anything you’ve added via the Import Template group, named as printer + process (e.g. Bambu Lab P1S - 0.08mm Fine @BBL P1S).

Pick the profile that matches the slicer you selected.

4. Confirm the slot count

Total Printer Slots auto-fills from your selected profile. Override it with the total AMS / CFS / ACE / CANVAS / MMU / Tool Changer slots your printer you’re printing the HueForge on has. For example, if you have a Bambu Labs printer with two AMS units that each hold 4 filaments each, that would be (4 × 2 = 8) — so you would enter 8 total printer slots.

The slot count drives whether filament-change G-code and/or pause G-code is emitted at each layer transition.

5. Set the project name + output folder

The Output group has:

  • Project Name — the basename of the exported 3MF
  • Output Folder — where to write it
  • Open 3MF after export — convenient for iterating
  • Save Project in Folder — also writes the HueForge Project file (.hfp) next to the 3MF

6. Glance at Project Settings

The Project Settings group is read-only — it summarizes the profile’s bed dimensions and the layer-height plan the plugin will use (usually a thick first layer for the white base, then your HueForge layer height for the color stack).

If the model overflows the bed, a red bed-fit warning appears — swap printers or scale the model before exporting.

7. Export

Click Export. The dialog closes; the 3MF lands in your output folder; if Open 3MF after export was on, your slicer launches with the file already loaded.

8. Slice in the slicer

Press the slicer’s Slice button. The print profile, filaments, extruder assignments, and filament changes are already wired — you should not need to touch them. Save the G-code, send it to your printer.

What can go wrong

  • Wrong slot count — pause G-code where you wanted filament changes, or vice versa. See Common issues.
  • Layer numbers don’t match Describe.txt — expected, see the layer-shift FAQ entry.
