European-built. ### Your designs stay yours. All slicing happens locally on your machine. Your 3D models, profiles, and G-code never leave your computer unless you explicitly send them somewhere. Suitable for air-gapped environments and secure manufacturing facilities. PrusaSlicer is based on the original open-source project Slic3r by Alessandro Ranellucci. ![Organic tree supports on a complex figurine showing minimal contact points](https://assets.prusa3d.com/cdn-cgi/image/width=800,height=600,quality=85,format=auto/99287f23-987c-4c5c-a7a0-b40e425c34b9.png) ### Less waste, cleaner surfaces. The software automatically generates organic-shaped supports that touch the model only where absolutely necessary. This results in dramatically less filament used, almost no marks on the finished surface, and supports that snap off by hand. Need full control? Paint support zones directly onto the model. ![Multi-material painting brush tool applied to a model with multiple color regions](https://assets.prusa3d.com/cdn-cgi/image/width=800,height=600,quality=85,format=auto/ecdd5163-1412-45c1-9527-082a0be58b1a.png) ### Multi‑material color painting Paint material regions directly on the model surface using a smart fill and brush tool. Full support for MMU3 and multi-extruder setups. Wipe-into-infill minimizes waste at transitions. For single-extruder printers, schedule filament changes at specific layers for basic multicolor prints without extra hardware. ![Cut tool splitting a large model with alignment pins shown at the cut interface](https://assets.prusa3d.com/cdn-cgi/image/width=800,height=600,quality=85,format=auto/35e6b4d0-f91c-47fd-8f4a-5549efb2deab.png) ### Too big? Split it, print it, snap it together. Model too big for the build plate? Split it with one cut. You choose where the plane goes, and the software adds alignment pins at the seam automatically. Print the pieces and snap them together. ## Get the best results with Prusa 3D printers Most Affordable ![Prusa MK4S kit](https://assets.prusa3d.com/cdn-cgi/image/width=1280,height=1280,quality=85,format=auto/b944a8a7-93e6-49b8-8a4c-1a006dc7904a.png) ### Prusa MK4S kit The ultimate STEM project - Entry-level printer with seamless operation - Open design for easy maintenance - Reliable performance [Get MK4S kit](https://www.prusa3d.com/product/original-prusa-mk4s-3d-printer-kit-5/) Bestseller ![Prusa CORE One+](https://assets.prusa3d.com/cdn-cgi/image/width=3898,height=4016,quality=85,format=auto/eb95b22f-36c6-4433-982a-f9fd5dc67b5f.png) ### Prusa CORE One+ The Flagship CoreXY - Benchmark speed with any material - Active chamber temperature control - Award-winning exoskeleton design [Get CORE One+](https://www.prusa3d.com/product/prusa-core-one/) The Bigger CORE One ![Prusa CORE One L](https://assets.prusa3d.com/cdn-cgi/image/width=340,height=340,quality=85,format=auto/c582296d-29d4-4158-8d13-9cdd57a8e877.png) ### Prusa CORE One L+ Effortless printing with advanced materials - Double the CORE One+ build space - Top heat distribution - Ready for more demanding projects [Get CORE One L](https://www.prusa3d.com/product/prusa-core-one-l-2/) ![PrusaSlicer with the Printables.com browser panel open showing model search results](https://assets.prusa3d.com/cdn-cgi/image/width=1200,height=780,quality=85,format=auto,fit=scale-down/beb56f03-35fb-46e6-b601-727f60db864f.png) No app switching ### The whole workflow in one window PrusaSlicer includes a built-in [Printables.com](https://www.printables.com/) browser.
