What is PrusaSlicer?

PrusaSlicer is a free, open-source, and frequently updated software tool designed to prepare 3D models for printing on FDM 3D printers. It takes 3D models and converts them into G-code, which is the set of instructions your 3D printer follows to create the object layer by layer. The software is packed with features for both beginners and advanced users, offering extensive control over print settings to optimize print quality, material usage, and printing time. While PrusaSlicer includes community profiles for various third-party printers, it offers over 180 tested and auto-updated profiles specifically for Original Prusa printers and popular filaments/resins, ensuring a highly optimized experience for Prusa users. It also comes bundled with a standalone G-Code Viewer for quick previewing of G-code from various popular slicers.
