摘要：三维打印技术的迅速成熟，变得无处不在。剩下的一个障碍是，大规模采用对象打印必须fi进入工作容积的三维打印机。我们提出一个框架，称为斩波器，分解大型三维物体成更小的部分，每个部分fi指标为印刷量。这些部分可以被组装成原始对象。我们制定了一系列的理想标准的划分，包括装配，具有部件少，不唐突的接缝，和结构的合理性。斩波器优化这些标准并生成一个分区自动或用户指导。我们的样机输出fi酮分解部分定制的接口连接器。我们证明的效力，斩波器的各种非平凡的真实世界的物体。



Abstract：3D printing technology is rapidly maturing and becoming ubiquitous. One of the remaining obstacles to wide-scale adoption is that the object to be printed must fit into the working volume of the 3D printer. We propose a framework, called Chopper, to decompose a large 3D object into smaller parts so that each part fits into the printing volume. These parts can then be assembled to form the original object. We formulate a number of desirable criteria for the partition, including assemblability, having few components, unob***siveness of the seams, and s***ctural soundness. Chopper optimizes these criteria and generates a partition either automatically or with user guidance. Our prototype outputs the final decomposed parts with customized connectors on the interfaces. We demonstrate the effectiveness of Chopper on a variety of non-trivial real-world objects.
