Open-source slicing has always been built on a tradition of collaboration and attribution. [Slic3r](https://github.com/Slic3r/Slic3r), created by Alessandro Ranellucci and the RepRap community, laid the foundation. [PrusaSlicer](https://github.com/prusa3d/PrusaSlicer) by Prusa Research built on Slic3r and acknowledged that heritage. [Bambu Studio](https://github.com/bambulab/BambuStudio) in turn forked from PrusaSlicer, and [SuperSlicer](https://github.com/supermerill/SuperSlicer) by @supermerill extended PrusaSlicer with community-driven enhancements. Each project carried the work of its predecessors forward, crediting those who came before.
OrcaSlicer began in that same spirit, drawing from BambuStudio, PrusaSlicer, and ideas inspired by CuraSlicer and SuperSlicer. But it has since grown far beyond its origins. Through relentless innovation — introducing advanced calibration tools, precise wall and seam control, tree supports, adaptive slicing, and hundreds of other features — OrcaSlicer has become the most widely used and actively developed open-source slicer in the 3D printing community. Many of its innovations have been adopted by other slicers, making it a driving force for the entire industry.
