Robot-assisted 3D printing has drawn a lot of attention because of its capability to fabricate curved layers that are optimized according to different objectives. However, the support generation algorithm based on a fixed printing direction for planar layers cannot be directly applied to curved layers as the orientation of material accumulation is dynamically varied. In this project, we propose a skeleton-based support generation method for robot-assisted 3D printing with curved layers.

Pipeline for curved support generation
- Computational domain generation from support envelop hull;
- Compatible curved support layers generation;
- Tree-like support skeleton calculation;
- Implicit solid construction;
- Support region extraction;
Dual-material Robot-assisted 3D Printing System
A 2-in-1 extruder is installed on the end-effector of the robot arm, different filaments can be controlled to pass through the Y-shape structure alternatively. A router is employed as the core of communication between the controller of UR5e, Duet3D, and the laptop PC.
