The rapid growth of the geriatric population in industrial societies is expected to increase the demand for prosthetic implants. Unfortunately, current products exhibit shortcomings such as inadequate sizing or excessive material strength both of which hamper the recovery of fractures. Selective laser melting (SLM), as a manufacturing method, is highly suited for optimizing the geometry and topology of products. However, SLM however, seems to restrict the manufacturing precision to mostly horizontal printing which is inefficient when considering the build envelope. Additionally, certain elongated geometries are subject to warpage when printed horizontally. To address these issues, our study investigated the feasibility of vertically oriented porous structures using SLM. It will report on two specific deficiencies, namely slanting and cluttering, that were revealed through X-ray computer tomography. To facilitate the manufacturing of slender, porous structures, the paper will offer and examine heuristics that minimize the defects. The preliminary results indicate that structures such as shell reinforcements and bio-inspired unit cells reduce the occurrence of slanting and cluttering and might serve as interim solutions for the printing of large filigree structures. The general findings suggest that more dedicated research is necessary to understand the relationship between geometrical features and manufacturing precision in SLM.

工业社会中老年人口的快速增长预计将增加对假肢植入物的需求。不幸的是，目前的产品表现出诸如尺寸不足或材料强度过大的缺点，这两者都阻碍了断裂的恢复。选择性激光熔化 (SLM) 作为一种制造方法，非常适合优化产品的几何形状和拓扑结构。然而，SLM 似乎将制造精度限制在大部分水平打印，这在考虑构建信封时效率低下。此外，某些细长的几何形状在水平打印时会发生翘曲。为了解决这些问题，我们的研究调查了使用 SLM 垂直定向多孔结构的可行性。它将报告两个具体的缺陷，即倾斜和杂乱，这些是通过 X 射线计算机断层扫描发现的。为了促进细长多孔结构的制造，该论文将提供并检查可最大限度减少缺陷的启发式方法。初步结果表明，壳增强材料和仿生单元细胞等结构减少了倾斜和杂乱的发生，并可作为打印大型花丝结构的临时解决方案。一般研究结果表明，需要进行更多专门的研究来了解 SLM 中几何特征与制造精度之间的关系。初步结果表明，壳增强材料和仿生单元细胞等结构减少了倾斜和杂乱的发生，并可作为打印大型花丝结构的临时解决方案。一般研究结果表明，需要进行更多专门的研究来了解 SLM 中几何特征与制造精度之间的关系。初步结果表明，壳增强材料和仿生单元细胞等结构减少了倾斜和杂乱的发生，并可作为打印大型花丝结构的临时解决方案。一般研究结果表明，需要进行更多专门的研究来了解 SLM 中几何特征与制造精度之间的关系。
