Abstract Porous structures exhibit superior properties compared to their non-porous counterparts, though they are challenging to design and fabricate. This paper presents a self-contained and user-friendly system that designs a porous structure by filling the spaces between a randomly generated point cloud and a closed boundary. It produces the STL dataset of the designed structure. The system generated STL datasets were used to fabricate some porous structures using a 3D printer. The fabricated structures exhibited randomly sized and distributed pores through which gasses and liquids could pass. These characteristics of the fabricated structures make them suitable for engineering and biomedical applications.

一种用于设计和 3D 打印多孔结构的系统

摘要 多孔结构与无孔结构相比表现出优越的性能，但它们的设计和制造具有挑战性。本文提出了一个自包含且用户友好的系统，该系统通过填充随机生成的点云和封闭边界之间的空间来设计多孔结构。它生成设计结构的 STL 数据集。系统生成的 STL 数据集用于使用 3D 打印机制造一些多孔结构。制造的结构表现出随机大小和分布的孔，气体和液体可以通过这些孔。制造结构的这些特性使其适用于工程和生物医学应用。
