Additive manufacturing (AM) revolutionizes the manufacturing industries for producing complex geometric parts with high accuracy and minimal production time. The current understanding of high strain rates material deformation behavior of AM parts under compressive loadings is limited. In this work, we performed high strain rates compressive loading test on stainless steel samples with Kolsky bar at room temperature. The test samples were fabricated by selective laser melting (SLM) process and the SLM is one of the AM methods. The samples had a layer thickness of 30 µm and five different layer orientations, such as 0⁰, 30⁰, 45⁰, 60⁰, and 90⁰ with three different global energy density (GED) values. The GED value of a sample is related to laser power, scan speed, hatch spacing, and layer thickness of the SLM process. In our study, we found the characteristic material deformation behavior depends on building layer orientations and the GED values.
