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.

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.

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.

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.

The ultimate STEM project

The Flagship CoreXY

Effortless printing with advanced materials

PrusaSlicer includes a built-in Printables.com browser. Find a model, import it to the build plate, slice, and send it to the printer without opening a separate app or downloading files manually.
Printables.com hosts over 2 million free models. It's open to all printer brands, no account required to browse.
