The next generation of 3D printing slicer software
Orca Slicer is a powerful, free, and open-source slicer application designed to convert your 3D models into precise G-code instructions that your 3D printer can understand and execute. Originally forked from Bambu Studio, which itself was derived from the legendary PrusaSlicer (formerly Slic3r PE), Orca Slicer combines the best features from multiple slicing software platforms while adding its own innovative capabilities that set it apart from other 3D printing slicers on the market.
Whether you're a hobbyist creating your first 3D Benchy boat, a maker prototyping functional parts, or a professional producing production-grade prototypes and end-use parts, Orca Slicer provides the comprehensive toolset you need to achieve exceptional print quality. The software supports an extensive range of 3D printers out of the box, from budget-friendly Creality Ender 3 machines to high-end Bambu Lab X1 Carbon printers, making it the perfect choice for makers and professionals at every level.
The 3D printing slicer market offers several options including Cura, PrusaSlicer, Simplify3D, and Bambu Studio. However, Orca Slicer stands out for several compelling reasons that make it the preferred choice for serious 3D printing enthusiasts:
Did you know? Orca Slicer is used by over 100,000 makers worldwide and processes millions of 3D prints each month. The software has been downloaded over 2 million times from GitHub alone.
A 3D printing slicer is the essential software bridge between your 3D model files (typically STL, OBJ, or 3MF format) and your physical 3D printer. The slicer takes your digital model and "slices" it into hundreds or thousands of horizontal layers, then generates the specific movement instructions (G-code) that tell your printer exactly how to create each layer.
Orca Slicer excels at this process by offering granular control over every aspect of the slicing operation. You can adjust layer heights from ultra-fine 0.04mm for detailed miniatures to fast 0.32mm layers for rapid prototypes. The software calculates optimal print paths, determines where to place support structures, manages cooling fan speeds, and orchestrates the complex dance of extruder movements that bring your digital designs into the physical world.
Orca Slicer incorporates several advanced technologies that contribute to superior print quality:
Packed with professional features that make 3D printing easier and more precise
Built-in calibration suite including temperature towers, flow rate tests, retraction tuning, and pressure advance calibration. Dial in your printer settings for each filament through systematic optimization. Generate calibration prints with a single click and achieve perfect results every time.
Plan and manage multiple print plates in a single project file. Organize batch printing workflows efficiently with accurate time and material estimates for each plate. Perfect for production runs, kit manufacturing, and organizing complex multi-part prints.
Compatible with Bambu Lab (X1 Carbon, P1S, A1), Prusa (MK4, MK3S+, Mini, XL), Creality (Ender 3, K1, CR-10), Voron (2.4, Trident, 0.2), VzBot, RatRig, Anycubic, Elegoo, Artillery, QIDI, Sovol, and hundreds more printers out of the box.
Fine-tune wall ordering, outer wall spacing, and precise control over external perimeters. Revolutionary scarf joint seams minimize visible layer lines for professional-looking results. Arachne variable-width walls adapt to your model geometry.
Seamless integration with Klipper/Moonraker, PrusaLink, OctoPrint, Repetier, and Bambu Lab cloud services. Start prints remotely, monitor progress in real-time, and receive notifications when prints complete. Full support for multi-printer farms.
Completely free with no hidden costs, subscriptions, or premium features. Open-source under GNU AGPL v3 license with transparent development on GitHub. Community-driven development ensures the software continues to improve based on user needs.
