OrcaSlicer on your Mac

Get OrcaSlicer safely

OrcaSlicer is free and open source, developed on GitHub. Download it from the official releases page, and choose the macOS file for your Mac. Several look-alike websites offer "OrcaSlicer downloads": the GitHub project is the source to trust.

Open the download, drag OrcaSlicer to Applications, and open it. On first launch, pick your Bambu Lab printer models in its setup wizard.

Connect your Bambu Lab printer

OrcaSlicer talks to Bambu Lab printers the way Bambu Studio does. For Bambu Lab printers it uses Bambu Lab's network plug-in, which it offers to install:

• Cloud mode: sign in with your Bambu Lab account; your bound printers appear on the Device tab.
• LAN Only mode: pick the printer found on your network and enter its access code. See LAN mode explained and where to find the access code.

The Mac and the printer need to be on the same network, and macOS may ask whether OrcaSlicer may find devices on your local network: click Allow.

OrcaSlicer or Bambu Studio?

Both slice for Bambu Lab printers and send jobs to them. OrcaSlicer is a community project with extra calibration tools and wider support for other printer brands; Bambu Studio is Bambu Lab's own. Many people keep both. See Bambu Studio on a Mac.

Follow prints after slicing

OrcaSlicer's Device tab shows a print's progress while OrcaSlicer is open. To keep it in view without the slicer, Bambu Bar puts progress and time left in your menu bar, with the camera, AMS filament, desktop widgets and notifications.

Setting it up is quick when OrcaSlicer already knows your printers:

• The direct version of Bambu Bar reads the printers' access codes and addresses from OrcaSlicer's settings on this Mac.
• The Mac App Store version asks you to choose OrcaSlicer's folder (in ~/Library/Application Support) once.
• With several printers, Add All sets them all up in one click.

Bambu Bar only reads OrcaSlicer's settings: it never changes them, and it isn't an OrcaSlicer plug-in. See getting started.
