## Overview

Bambu Studio is a desktop 3D-printing slicer. Its main user workflow is to prepare models on managed plates, configure geometry and print settings, slice them into G-code, then inspect or send the result for printing. The README also describes remote monitoring and control; the tree includes device-management and filament-manager code supporting that product area. Core slicing and GUI wiring were not sampled, so those paths use existing enclosing directories and the graph shows only the documented workflow at a subsystem level.

Main entry points: [`src/slic3r/GUI/DeviceManager.cpp`](https://github.com/bambulab/bambustudio/blob/master/src/slic3r/GUI/DeviceManager.cpp) (Device manager), [`src/slic3r`](https://github.com/bambulab/bambustudio/tree/master/src/slic3r) (Slicing algorithms), [`src/slic3r/GUI`](https://github.com/bambulab/bambustudio/tree/master/src/slic3r/GUI) (Project workflow), [`src/slic3r/GUI/Gizmos/GLGizmosManager.cpp`](https://github.com/bambulab/bambustudio/blob/master/src/slic3r/GUI/Gizmos/GLGizmosManager.cpp) (Painting and supports)
