摘要: Additive manufacturing (AM) is replacing conventional techniques due to its ability manufacture complex structures with near-net shape and reduced material wastage. However, the poor surface integrity of AM parts deteriorates service life components. The should be subjected post-processing treatment for improving fatigue life. In this research, maraging steel printed using direct metal laser sintering (DMLS) process influence grinding on additively manufactured was investigated. For purpose, experiments were performed under two different environments such as dry cryogenic conditions a cubic boron nitride (CBN) wheel. results revealed that roughness could by about 87% condition over grinding. tests carried out additive materials exposed substantial increase 170% in their when
