What carries over

What comes across

  • Plates and where everything sits on them.
  • Objects and their parts.
  • Which filament prints what: each object’s and part’s filament, and painted colors.
  • Filament colors, except in UltiMaker Cura (below).
  • Color changes at their heights, and height range modifiers.
  • Your print settings that the target slicer has, converted to how it writes them.
  • The printer and filament presets of the target slicer, for your printer. See below.

Your original file is never changed. Every translation is a new file.

Presets

Each target uses the printer preset you chose in that slicer’s own install, so the project opens with a printer your slicer knows, and the print settings start from that printer’s own process preset.

Each filament is matched to a filament preset installed in the target slicer for your printer: the same brand and name when it’s there, otherwise the generic preset of that type (Generic PLA, Generic PETG, …), otherwise the closest preset of the same type. It never swaps one material for another. The slot keeps the project’s color. A matched filament takes the preset’s own settings, so changes the project’s author made to a filament preset don’t come across.

Settings that don’t match

Slicers don’t all have the same settings, and they name and limit some of them differently.

  • A setting the target names differently is renamed, and a value outside what the target accepts is brought within it.
  • A setting the target doesn’t have, or has no equivalent for, keeps the target preset’s value.

Details sums this up after each run: Adjusted 4 setting(s) that PrusaSlicer names or limits differently. and 12 setting(s) have no match in PrusaSlicer and keep its preset’s values. Lines marked ⚠ are worth reading before you print.

By target slicer

Bambu Studio, Orca Slicer and their relatives

Snapmaker Orca, Creality Print, Anycubic Slicer Next, Elegoo Slicer, Flash Studio Desktop and QIDI Studio work like Orca Slicer and Bambu Studio. Filaments without a slot are added after your printer’s slots, for you to place in the slicer. See Filaments and printer slots.

On a printer with several toolheads, such as the Snapmaker U1, the project has one filament per toolhead, as the slicer expects: extra toolheads repeat the last slot’s filament.

PrusaSlicer, QIDISlicer and SuperSlicer

The project gets one filament per extruder of your printer (five for an MMU3). Filaments beyond that print with slot 1 unless you merge them yourself. Color changes come across as PrusaSlicer color changes, plate by plate.

UltiMaker Cura

  • One file per plate: a Cura project holds one build plate.
  • Cura’s stock materials of each filament’s type. Filament colors don’t carry over to Cura.
  • Color changes become a Filament Change post-processing step at the matching layers. Pauses don’t carry over; Details lists them.
  • Your own Cura printer settings, such as your start G-code and bed size, stay as they are.
  • The nozzle comes from the target’s Nozzle, since a Cura printer doesn’t name one.

Things to check in the slicer

A translated project is ready to slice, but have a quick look before printing, as you would with any project from someone else:

  • The plates, and that everything is on the bed.
  • The filaments in each slot, and the colors you have loaded.
  • Anything the Details panel marked with ⚠.
