FAQs

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.

1. Is PrusaSlicer free to use?

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.

2. Do I need a Prusa printer to use PrusaSlicer?

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.

3. Which operating systems support PrusaSlicer?

PrusaSlicer is available for Windows, macOS, and Linux. The interface and performance are consistent across platforms, so you can switch systems without losing functionality.

4. Can I import STEP files directly into PrusaSlicer?

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.

5. What file formats does PrusaSlicer support?

PrusaSlicer accepts STL, 3MF, OBJ, AMF, and STEP files. It exports standard G-code, which is compatible with most FDM 3D printers.

6. What’s the difference between Simple, Advanced, and Expert modes?

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.

7. How does PrusaSlicer handle multi-material printing?

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.

8. Are there built-in profiles for third-party printers?

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.

9. Does PrusaSlicer support organic supports like tree supports in Cura?

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.

10. How often is PrusaSlicer updated?

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.

11. Can I preview my sliced model before printing?

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.

12. Does PrusaSlicer work for resin printers?

Yes, PrusaSlicer includes MSLA (resin printing) support. It offers features like layer exposure settings, support generation, and resin-specific slicing parameters.

13. Can I use PrusaSlicer without an internet connection?

Absolutely. PrusaSlicer works entirely offline. However, some features like auto-updates or integration with Prusa Connect do require internet access.

14. Is there a way to share or back up my custom profiles?

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.

15. What makes PrusaSlicer different from Cura or OrcaSlicer?

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.
