Orca slicer is a powerful slicer for FFF (FDM) 3D Printers.
OrcaSlicer is originally forked from Bambu Studio which is forked from PrusaSlicer which is forked from Slic3r.
This is free and open source software.
Key Features
- User-friendly interface with intuitive drag-and-drop design with pre-made profiles for popular printers.
- Auto-calibration for all printers – comprehensive suite: temperature towers, flow rate, retraction & more for optimal performance.
- Sandwich (inner-outer-inner) mode – An improved version of the External Perimeters First mode. Use varied infill patterns and accurate hole shapes for improved clarity.
- Precise wall and seam control – adjust outer wall spacing and apply scarf seams to enhance print accuracy.
- Overhang and support optimization – modify geometry for printable overhangs with precise support placement.
- Polyholes conversion support.
- Granular controls and customization – fine-tune print speed, layer height, pressure, and temperature with precision.
- Network printer support – seamless integration with Klipper, PrusaLink, and OctoPrint for remote control.
- Wide printer compatibility – supports a broad range of printers: Bambu Lab, Prusa, Creality, Voron, and more.
- Cross-platform support – runs under Linux, macOS, and Windows.
