Current porous structure design methods in additive manufacturing (AM) lose accuracy in data model transformations along the processing chain and are difficult to consider manufacturability and post-processing issues. In addition, the design and printing preparation is costly due to large number of fine features and their related operations. To solve these problems with an aim to save time in design and printing preparation but ensure manufacturability and easy post-processing, this paper proposes an implicit design method using printing toolpaths to construct printable parametric porous structures. Experimental case studies demonstrated the feasibility, efficiency and application potential of the proposed method.

当前增材制造 (AM) 中的多孔结构设计方法在沿加工链的数据模型转换中失去了准确性，并且难以考虑可制造性和后处理问题。此外，由于大量精细特征及其相关操作，设计和印刷准备成本高昂。为了解决这些问题，以节省设计和打印准备时间，同时确保可制造性和易于后处理，本文提出了一种使用打印工具路径构建可打印参数多孔结构的隐式设计方法。实验案例研究证明了所提出方法的可行性、效率和应用潜力。
