We propose a method for the automatic segmentation of 3D objects into parts which can be individually 3D printed and then reassembled by preserving the visual quality of the final object. Our technique focuses on minimizing the surface affected by supports, decomposing the object into multiple parts whose printing orientation is automatically chosen. The segmentation reduces the visual impact on the fabricated model producing non‐planar cuts that adapt to the object shape. This is performed by solving an optimization problem that balances the effects of supports and cuts, while trying to place both in occluded regions of the object surface. To assess the practical impact of the solution, we show a number of segmented, 3D printed and reassembled objects.

优化对象分解以减少 3D 打印中的视觉伪影

我们提出了一种将 3D 对象自动分割成多个部分的方法，这些部分可以单独进行 3D 打印，然后通过保留最终对象的视觉质量来重新组装。我们的技术专注于最小化受支撑影响的表面，将对象分解成多个部分，其打印方向是自动选择的。分割减少了对制造模型的视觉影响，产生适应物体形状的非平面切割。这是通过解决平衡支撑和切割效果的优化问题来执行的，同时尝试将两者放置在物体表面的遮挡区域中。为了评估该解决方案的实际影响，我们展示了许多分段、3D 打印和重新组装的对象。
