Before you install
Check the current system requirements and choose the installer or package offered for your operating system on the official download page. Download only from Prusa Research or a distribution source linked by the project.
Windows
- Open the official PrusaSlicer download page and select the Windows build.
- Run the downloaded installer and review the destination folder and available options.
- Complete setup, then launch PrusaSlicer from the Start menu.
- If Windows displays a security prompt, verify the publisher and file source rather than bypassing warnings blindly.
macOS
- Download the macOS package from the official source.
- Open the downloaded disk image or package and follow the current on-screen instructions.
- Move the application to Applications if the installer workflow requests it.
- On first launch, follow macOS security prompts only after confirming the application came from the official source.
Linux
Linux packaging can vary by distribution and release. Use the package type and instructions currently published by PrusaSlicer or your trusted distribution source. Check dependencies and permissions before running downloaded binaries. Do not assume an AppImage, Flatpak or archive is available for every release.
First launch
Run the Configuration Wizard, choose the exact printer model and nozzle size, then select a filament profile that matches the material loaded. If your printer is not listed, use manufacturer documentation to configure its dimensions, firmware flavour, extruder count and start/end G-code. Do not select a similar-looking printer profile as a substitute without checking the specifications.
