Cura
Cura is a free, open-source slicing software for 3D printing that converts 3D models into machine-readable G-code instructions. It is used by hobbyists, engineers, educators and professionals to prepare models for printing on a wide range of FDM (Fused Deposition Modeling) 3D printers, including Ultimaker machines and many third-party printers. The app offers features like layer preview, infill patterns, support generation, print-time estimation, and integration with popular design tools. Cura is maintained by Ultimaker and is available for Windows, macOS and Linux.

1 suggestionCura now ships with a native Apple Silicon build. The official download page at cura-slicer.org offers separate ARM and Intel installers for macOS — you will want the "Download for macOS ARM" option (labelled for M1, M2, M3 chips) rather than the Intel version. Once you download and install the native build, your existing printer profiles, settings and recent files will carry over. If you are still running an older version of Cura on your Mac, downloading version 5.10.2 (or any later version) from the official site will automatically give you the native Apple Silicon build when you select the ARM download. This will deliver noticeably faster slicing, better responsiveness in the model preview, and improved battery life compared to the Intel build running under Rosetta 2.
