Topology Optimization of Self-supporting Structures for Additive Manufacturing via Implicit B-spline Representations

Nan Zheng, Xiaoya Zhai, Jingchao Jiang, Falai Chen

Abstract: Highlights•Analytical conditions for non-self-supporting constraints are derived based on the implicit B-spline representation.•Several acceleration techniques are employed to achieve high computational performance.•The self-supporting constraints are imposed on boundary points, significantly reducing unnecessary constraint calculations.
