The feasibility of printing structures made of high-alloy TRIP steel by Electron Beam Melting (EBM) is demonstrated in this study. Three different structure geometries are discussed. During the melting process approximately 1.4 wt% manganese evaporate independent of the printed structure. The structures differ in the arrangement of cell walls and the local material distribution in the in-plane array. To evaluate the strength of the structures, quasi-static compression tests were carried out in out-of-plane and in-plane direction. It is shown, that a homogenous distribution of cell walls over the structure cross section and stiffened cell walls with short distances between the cell wall nodes contribute to a high compressive strength.

这项研究证明了通过电子束熔化（EBM）印刷由高合金TRIP钢制成的结构的可行性。讨论了三种不同的结构几何形状。在熔化过程中，大约有1.4 wt％的锰蒸发，而与印刷结构无关。结构的不同之处在于，细胞壁的排列和面内阵列中的局部材料分布。为了评估结构的强度，在平面外和平面内方向进行了准静态压缩测试。结果表明，孔洞壁在结构截面上的均匀分布和孔洞壁节点之间距离短的硬化孔道壁有助于高抗压强度。
