3MF Translator

Your first translation

This walks through one translation from start to finish. It assumes you have set up your printers.

1. Open the project

Drag the .3mf onto the 3MF Translator window, or click Browse….

The line under the file name says what you opened: the slicer it came from, its printer, and how many objects and plates it has. The panels under it show the project as it is:

  • Filament: the project’s filaments and their colors. Collapsed, it shows the colors as small numbered squares.
  • Process: the project’s print settings.
  • Plates: every plate in 3D, in the filament colors with the color changes. Click a plate’s number (or the plate itself) to frame it; double-click to see all plates again. Drag to turn the view, including from below for face-down prints, and scroll to zoom. Drag the handle at the bottom to make the view taller.

These panels show the source; you can look at them while a translation runs.

2. Check your targets

Pick the group’s tab. For each target row, check:

  • Plates: All, or only the plates you want. See Plates.
  • Filaments: Source means the project’s filaments go into the printer’s slots as they are. If the project has more filaments than the printer has slots, the row says so in amber; open Filaments to merge them. See Filaments and printer slots.
  • Any amber line about a plate that won’t fit the printer. Rotate 90° may fix it.

3. Translate

Click the green button at the bottom right, or File → Translate (Ctrl+T).

  • With one target on, it reads Translate and Save Project… and asks where to save the file.
  • With several, it reads Translate and Save 3 Projects… (with your count) and asks for a folder. Each file is named after the project and the target, for example benchy-bambu-lab-h2d.3mf.

The bar beside the button shows how far it has got. Several targets are translated at once when your computer has the memory for it.

UltiMaker Cura gets one file per plate, since a Cura project holds one build plate: benchy-ultimaker-s5-plate1.3mf, benchy-ultimaker-s5-plate2.3mf and so on.

4. Read the results

When it’s done, a message lists what was saved, anything that failed and why, and the slicers it opened.

Details, at the bottom of the window, says in plain words what changed for each target, for example:

  • From a Bambu Studio project.
  • Adjusted 4 setting(s) that PrusaSlicer names or limits differently.
  • 12 setting(s) have no match in PrusaSlicer and keep its preset’s values.

Lines marked ⚠ are worth reading before you print. See What carries over.

5. Open it in your slicer

With Open After ticked, each project opens in the slicer it was made for. Otherwise, open the file from your slicer as usual. Check the plates and filaments, then slice and print as you always do.
