📜 History of PrusaSlicer

PrusaSlicer didn’t appear out of nowhere — it has its roots in one of the earliest open-source slicers.

• Origins in Slic3r (2011): The story begins with Slic3r, an open-source slicing project created by Alessandro Ranellucci within the RepRap community. Launched in 2011, Slic3r quickly became popular because it was free, flexible, and community-driven.
• Prusa Research Adoption (2016): For several years, Prusa Research relied on Slic3r as the default slicer for its printers. However, as the company grew, it needed faster development cycles and more advanced features. In 2016, Prusa forked the Slic3r codebase to create its own customized version, initially called Slic3r Prusa Edition (Slic3r PE).
• Rebranding to PrusaSlicer (2019): As the software matured and diverged significantly from the original Slic3r, Prusa officially renamed it PrusaSlicer in 2019. This marked the point where it became a fully independent project, though still open-source and licensed under the GNU AGPLv3.
• Continuous Development: Today, PrusaSlicer is actively maintained by Prusa Research with regular updates. It supports both FFF (Fused Filament Fabrication) and MSLA (Masked Stereolithography) printers, integrates with Prusa Connect for remote management, and connects directly to the Printables.com model library.

🔑 Why This Matters

• Community Roots: Knowing that PrusaSlicer is based on Slic3r highlights its open-source heritage.
• Rapid Innovation: The fork allowed Prusa to add features like modifier meshes, advanced supports, and SLA slicing much faster than the original project.
• Reliability: Because it’s backed by Prusa Research, users benefit from professional development and testing while still enjoying the flexibility of open-source software.
