CAD Representations and Process Planning Algorithms for Layer Manufacturing of Heterogenous Reject

分层制造指的是在计算机控制下，通过逐层沉积材料来制造物理部件。使用分层制造可以制造多材料结构以及嵌入预制件。介观器件和功能组件也可以直接制造。分层制造的自动化依赖于非同质对象的适当CAD表示和从CAD模型中提取工艺信息的计算机算法。现有的CAD系统无法表示非均匀的、多材质的物体。该项目解决了这些问题。研究任务包括算法的设计和实现，以及随后在几种介质中制造多材料部件。

Layered manufacturing refers to the fabrication of a physical part by depositing material, layer-by-layer, under computer control. The fabrication of multi- material structures as well as the embedding of prefabricated components is possible using layered manufacturing. Mesoscopic devices and functioning assemblies can also be made directly. The automation of layered manufacturing depends on proper CAD representations of non-homogeneous objects and computer algorithms for extracting process information from the CAD models. Present CAD systems are unable to represent non-homogeneous and multi-material objects. This project addresses these problems. Research tasks include the design and implementation of algorithms and the subsequent fabrication of multi-material parts in several media.
