增材制造（AM）中零件的构建方向对零件的质量、工艺规划、后处理、加工时间和成本等产生复杂的影响。确定零件的最佳构建方向是增材制造工艺规划的主要内容之一。本文为新的增材制造工艺（连续纤维多材料沉积）开发了构建方向优化策略，以提高零件质量，同时减少生产时间和成本。首先，通过使用表面形状特征以及从新开发的增材制造工艺的具体特征和约束导出的相关规则，生成一组有限的替代构建方向；然后，应用多属性决策算法根据预设偏好确定最佳方向。提出了一个案例研究来进行演示。
Build orientation of a part in Additive Manufacturing (AM) has complex effect on part's quality, process planning, post-processing, processing time and cost, etc. The identification of the optimal build orientation for a part is one of the main contents of process planning in AM. In this paper, a build orientation optimization strategy is developed for a new AM process, multi-material deposition with continuous fibers, to improve the part quality while reducing the production time & cost. First, a set of finite alternative build orientations are generated by using surface shape feature with associated rules derived from the specific characteristics and constraints of the new developing AM process; then, a multi-attribute decision making algorithm is applied to determine the optimal orientation according to preset preferences. A case study is presented for demonstration.
