What is orcaslicer?

OrcaSlicer is a slicer, meaning software that takes a 3D model and converts it into the exact machine instructions, called G-code, that a 3D printer follows layer by layer to print it. This repository is a copy of the OrcaSlicer project, which supports a wide range of printer brands including Bambu Lab, Prusa, Voron, VzBot, RatRig, and Creality. The README lists several print quality features: calibration tools for things like temperature and material flow rate, fine control over wall thickness and where the visible seam on a print appears, an option for using different infill styles on the inside versus the outside of a print, and automatic adjustment of overhangs and support material so difficult shapes print more reliably. It also supports remote printer control through common tools like Klipper, PrusaLink, and OctoPrint, automatic adhesion helpers called brims, and a drag and drop interface with ready made profiles for popular printers. The project has a public wiki that explains its settings in detail and how to calibrate a printer for best results. Installers are provided for Windows, with both a full installer and a portable build, and for Mac, with separate downloads for Apple Silicon and Intel chips, along with instructions for getting past macOS's security warning on unsigned apps. On Linux, it is distributed as an AppImage that may need a permission change before it will run. The README includes a warning that some lookalike websites impersonate the official OrcaSlicer site and may lead to unsafe downloads, and asks users to report those sites if they encounter them. The project has both stable releases and nightly builds for people who want the newest in-progress changes. The README does not clearly state its license in the material provided.
