%description
Bambu Studio is a feature-rich 3D printing slicing software designed for
Bambu Lab 3D printers and compatible with other 3D printer brands. It is
a fork of PrusaSlicer with enhanced features including advanced support
generation, multi-color printing, cloud integration, and project-based
workflows with optimized slicing algorithms.
