3D打印氧化锆TPMS立方结构的抗压性能研究

时间:2025-03-11 21:57来源:99643
创建了基于数学表面的三维多孔细胞材料,称为三重周期性极小表面(TPMS)。它们的结构不具有任何接头或者不连续性从而使对应力集中的影响最小化。

摘要:从自然界获得灵感,三重周期性最小表面(TPMS)被定制为设计多孔材料的内部孔结构的有前景的工具;3D打印是一种利用成形装置基于零件或物体的三维模型数据以物质积累的形式建立实体的技术[1]。在本文中,将三重周期极小曲面(TPMS)用来创造氧化锆细胞多孔材料;而3D打印制造这些氧化锆细胞多孔材料。首先对多孔材料的泡孔空间几何分布模型进行了建模和分类;分别是PCELL, IWP和S14这三种结构;然后利用3D打印技术制得了这3种多孔空间点阵结构的氧化锆试样,最后对试样的空间多孔点阵结构类型及孔隙率与材料抗压强度性能进行了研究;结果表明,S14和IWP具有类似的机械响应,此外,发现它们具有比PCELL更高的抗压强度。

Study on Compressive Strength Properties of 3D Printing Zirconia TPMS Cubic Structure

Abstract:Inspired by nature, triple periodic minimal surface (TPMS) is customized as a promising tool for designing the internal pore structure of porous materials; 3D printing is based on 3D model data of parts or objects using forming equipment to accumulate material The method of manufacturing entity technology. In this paper, a triple periodic minimal surface (TPMS) was used to create zirconia cell porous materials; 3D printing was used to fabricate these zirconia cell porous materials. Firstly, the modeling and classification of the cellular space Distribution model of porous materials were carried out. The three structures were PCELL, IWP and S14. Then the zirconia test of these three kinds of cell space lattice structures was made using 3D printing technology. In the end, the structure and porosity of the space cell lattice and the mechanical properties of the material were studied. The results show that S14 and IWP. have similar mechanical responses. In addition, they have been found to have higher compressive strength than PCELL.
