Purpose: The objective of this study is to comprehensively investigate the printability characteristics of a selective laser melting (SLM) system, which will be achieved through the development of a benchmark test part. In addition, the effect of the build location on the dimensional accuracy and precision of 316 L stainless steel parts produced by SLM was thoroughly evaluated. Design/methodology/approach: The benchmark part was designed using Catia CAD software. Parts were printed using a professional SLM 3D printer and 316L stainless steel powder as a material. Findings: The results showed that to achieve exceptional dimensional accuracy in SLM parts, it is important to select the build location carefully. They also highlighted the critical role of gas distribution control in improving the precision of layer-by-layer deposition. The thorough evaluation of dimensional deviations at different build locations showed that optimal results were consistently achieved at position F within the build cham-ber. Research limitations/implications: Further studies could investigate other factors affecting dimensional variations and surface roughness and enhance the comprehension of the interactions between the process parameters and the building position on the build platform. Originality/value: The paper outlines the creation and production of a benchmark model used to assess the maximum capacity of SLM systems in manufacturing parts with ultimate dimensional precision. The effects of build location on dimensional accuracy are also explored in the given study.
