At prusaslicer.info, we understand that navigating slicing software especially one as feature-rich as PrusaSlicer can raise a lot of questions. Whether you’re new to 3D printing or already experienced, this page answers the most common and practical questions we hear from users around the world.
If you’re looking to set up your printer, optimize your prints, or understand how PrusaSlicer compares to other tools, you’ll likely find your answers here.
Yes, PrusaSlicer is completely free and open source. You don’t need a subscription or license to use any of its features, and it’s supported by a strong developer and user community.
Not at all. While PrusaSlicer is developed by Prusa Research, it works well with many third-party printers. You can either use community-supported profiles or create your own by entering the printer’s specifications.
PrusaSlicer is available for Windows, macOS, and Linux. The interface and performance are consistent across platforms, so you can switch systems without losing functionality.
Yes, one of the standout features is the ability to import STEP files. This means you can bring in models directly from CAD software without converting them to STL first, which helps maintain dimensional accuracy.
PrusaSlicer accepts STL, 3MF, OBJ, AMF, and STEP files. It exports standard G-code, which is compatible with most FDM 3D printers.
These modes control the level of access to settings. Simple is beginner-friendly, Advanced unlocks more slicing options, and Expert gives full control over all print parameters.
PrusaSlicer supports multi-material printing, including full integration with the Prusa MMU2S. You can assign different filaments to model parts, use soluble supports, and optimize purge processes using wipe towers.
Yes, PrusaSlicer includes community-verified profiles for many popular non-Prusa printers. If yours isn’t listed, you can set one up manually by entering your machine’s specifications.
PrusaSlicer uses its own system called “organic supports,” which serve a similar purpose. You can also manually paint supports on your model to control where they appear.
The software receives regular updates with new features, bug fixes, and printer profiles. These updates are community-driven and often reflect user feedback and the latest industry trends.
Yes, PrusaSlicer provides a detailed G-code preview that shows the model layer by layer. It also displays nozzle paths, print time estimates, and filament usage.
Yes, PrusaSlicer includes MSLA (resin printing) support. It offers features like layer exposure settings, support generation, and resin-specific slicing parameters.
Absolutely. PrusaSlicer works entirely offline. However, some features like auto-updates or integration with Prusa Connect do require internet access.
Yes, you can export and import both printer and filament profiles. Saving your projects in the 3MF format also preserves your model, settings, and modifiers in one file.
While Cura focuses on user simplicity and OrcaSlicer emphasizes performance with certain hardware, PrusaSlicer offers a balanced mix of control, compatibility, and advanced features. It’s especially popular among users who value customization and open development.
