摘要: 3D打印技术在制造复杂产品和定制化产品方面较传统制造工艺有天然的优势, 在医疗、教育、娱乐、时尚等领域有广泛的应用. 受到可旋转的风铃结构的启发, 提出一种生成任意简单多边形的多层旋转体的方法. 对于给定的简单多边形计算其内部轮廓与旋转轴, 使之能够在上层空间内自由旋转而不发生碰撞, 同时面积最大; 经过迭代最终在多边形内生成多层轮廓结构; 进一步, 对轮廓结构进行拉伸并添加关节, 建模得到一个完整的3D几何模型, 以平板状态直接进行一体化3D打印, 且无需后期组装. 实验结果表明, 该方法结果符合预期, 生成的免组装可旋转模型可以在较短的时间内成型完成.

3D Printed Rotatable Wind Chime Modeling from a Simple Polygon

abstract: 3D printing is maturing rapidly with advances in materials and mechanism, and has begun to flourish in various design disciplines, such as product design, medical device design, entertainment and fashion design etc. Inspired by the structures of rotatable wind chimes, we propose a method for modeling a 3D printable, collision free, multi-layer rotatable model from an arbitrary simple polygon. Given a simple polygon, we compute a series of internal contours and the corresponding rotating axis, such that each contour can rotate around its axis with no collision in the space. We construct the 3D printable model by adding joints along with each axis. The model can then be fabricated in a planar state, in one piece without assembly. Experiments show that our results are of both rotatable properties and aesthetics, and can be 3D printed with high efficiency.
