Converting 3MF projects in the Meshory app

Updated Oct 28, 2026 · 6 min read

Convert the 3MF projects in your library between Bambu Studio, OrcaSlicer, PrusaSlicer, Creality Print, Flash Studio and more, with your own slicer presets.

Opening one slicer's 3MF in another often keeps only the geometry: a multi-plate project lands on one plate, and the supports and infill you set up are gone.

Tools, in the sidebar, holds the 3MF converter. It takes a project saved by Bambu Studio, OrcaSlicer, Snapmaker Orca, PrusaSlicer, Creality Print, Anycubic Slicer Next or Flashforge's Flash Studio and writes a new 3MF for one of the others. Printer and material settings come from the destination slicer's own profiles, and the print settings you changed in the source project, such as supports, infill and walls, come across. It runs offline, and your original file is never modified. For a one-off conversion without the app, the free web converter does the same in your browser. The converter is in beta: check placement and supports in the destination slicer and slice again before you print. Tools also holds the Nameplate builder and the Vase generator.

Step by step

1. 1Open Tools from the sidebar and choose 3MF converter. Drop a 3MF project onto the page, pick one from disk, or pick one from your library; the library picker shows each project's thumbnail and lets you browse by folder.
2. 2Choose the destination: slicer, printer, nozzle and print profile. The print profile starts on one with your project's layer height, or on the printer's default when none matches. Every picker is searchable. The profiles are included with Meshory, so the destination slicer does not have to be installed on this computer.
3. 3Match materials. Each color in the source gets a filament from the destination slicer's catalog. One filament for every color is a single choice, and a color the project never uses can be removed from the export. Save turns on the moment every color has a filament.
4. 4Save the converted 3MF. By default it lands in the same folder as the original, named after it with the destination slicer added, and a name that is already taken gets a number rather than overwriting anything. Untick Save in the same folder as the original to choose a folder instead. Keep my print settings is on by default; untick it to use the destination print profile as it is. When the file is saved, Open in slicer hands it to the destination slicer.

Convert on the way to your slicer

You don't have to start in Tools. When you open a 3MF in a slicer other than the one that saved it, and Meshory can convert for that slicer, a Made in dialog offers Convert & open: Meshory saves a copy for your slicer next to the original and opens it, or shows the conversion report first when something needs a check. Open original anyway skips the conversion, and Don't warn me about files from other slicers turns the question off. To convert without opening anything, right-click a 3MF in the library or inside an archive and choose Convert 3MF…, then pick the slicer to convert to.

What changes, and what stays

• Geometry stays intact, and every plate of a multi-plate project lands in the one new file. Painted colors follow the filaments you assigned.
• Printer and material settings come from the profiles you chose.
• Print settings you changed in the source project come across (except to or from PrusaSlicer), for the whole project and for single objects or parts. That includes supports with their type and style, infill, walls, top and bottom layers, seams, brims, ironing and printing by object. A value the destination slicer cannot use, or would reset when it opens the project, stays at the destination profile's setting, and the conversion report says why for each one.
• Layer height and speeds come from the destination print profile you pick. From the release after 1.12.0, a conversion for the same printer and nozzle also brings across the layer height, speeds, line widths, accelerations, flow and hole compensation you changed. Filament changes and pauses set on the layer slider come across at the same heights, and custom G-code written for the source printer is left out. Height ranges come across with their filament, and with their own layer height and settings while Keep my print settings is on.
• Variable layer height and the toolpaths of the last slice are removed, so the destination slicer slices from scratch.
• Plate placement is kept relative to the bed center, and the converter checks whether each plate fits the destination printer.

After a save, a conversion report above the setup lists what came across, what the destination profile set and what was left out. It opens by itself when something needs a check, such as a setting the destination slicer would not accept, and Copy as text puts the whole report on the clipboard. If a save fails, the same place says why nothing was saved and what to do next.

Using the profiles installed with your slicer

Next to the destination picker, Included uses the profile set bundled with Meshory and Installed uses the presets your slicer runs on this computer, your own custom presets included. Meshory looks in the slicer's own folders; if it finds nothing there, Locate profiles folder lets you point it at the slicer's resources/profiles folder. Reading installed profiles never writes to them. When the slicer installed here is older than the included profiles, the converter starts on your installed presets, warns you if you switch to Included, and leaves print settings at the destination profile's values, because an older slicer can reject settings it does not know.

The profile library

Tools also has a Profile library: a read-only view of the printer, filament and process presets installed with your slicers, searchable by printer, material or brand. Convert with these profiles opens the converter on that slicer's installed set. A preset that does not name the printers it applies to is listed but marked as one the converter cannot offer.
