FAQ

Frequently asked questions.

Does the app cost anything?

No. The 3MF Katalog Manager is completely free and open source under the MIT License. There's no subscription and no ads.

Why do Windows and macOS show a warning on first launch?

The installers aren't digitally signed, because the certificates for that cost a lot of money. So Windows shows a SmartScreen warning and macOS a Gatekeeper message. On Windows, click “More info” and then “Run anyway”. On macOS, right-click the app and choose “Open”. If you want to be sure, verify the file with the SHA256 checksums.

Which variant should I pick, with or without STEP preview?

If you only use 3MF, STL or OBJ files, the smaller variant without STEP preview is enough. If you also want to view CAD files (.step/.stp), take the variant with STEP preview. Otherwise both are identical.

Are my files moved or uploaded?

No. The catalog only remembers where your files are and stores its data locally on your computer. Nothing is uploaded to a cloud.

Which slicers are supported?

Bambu Studio, OrcaSlicer, PrusaSlicer, SuperSlicer and UltiMaker Cura are detected automatically. You can add any other slicer yourself. The app reads the real filament usage from files sliced in Bambu Studio or OrcaSlicer.

I have a problem or an idea. Where should I go?

The quickest way is on Discord in #help-installation, #bug-reports or #feature-requests. You can also report bugs directly on GitHub.

Bring order to your models.
