Summary: This paper presents a multi-jet polishing (MJP) method for post-processing additively manufactured (AMed) surfaces, particularly those with complex surface geometries. Through systematic polishing tests on 316L stainless steel (SS) prepared by powder bed fusion, the polishing performance and the effect of key parameters are evaluated. The results demonstrate the effectiveness of MJP in obtaining nanometric surface roughness on AMed 316L SS, indicating the potential wide application of MJP for post-processing complex AMed surfaces.

Summary: This study investigates the hot deformation behavior and recrystallization mechanisms of selective laser melted 316L stainless steel. The results show that the development of substructures and continuous recrystallization are the main softening mechanisms during thermomechanical processing. The presence of cellular substructures facilitates recrystallization, and both discontinuous and geometric dynamic recrystallization contribute to the deformation process.

Summary: 316L stainless steel is the preferred material for applications that require a combination of mechanical strength and corrosion resistance, such as in the biomedical field. Additive Manufacturing (AM) technologies offer new design solutions, but the microstructure, defects, and surface characteristics of AM materials are different from traditional processing routes, making the evaluation of long-term durability crucial.

Summary: The study utilized the cold metal transfer (CMT) process to fabricate 316L stainless steel and compared its dynamic characteristics with annealed wrought 316L, finding that CMT 316L exhibited higher yield strength and flow stress at small strains due to a special cellular structure in the matrix. The study also showed that the average twin thickness of CMT 316L decreased with the increase of strain rates during dynamic compressions.

Summary: The rapid growth of the geriatric population in industrial societies is expected to increase the demand for prosthetic implants. However, current products exhibit shortcomings that hamper recovery of fractures. Research on SLM-manufactured vertically oriented porous structures revealed deficiencies and proposed heuristic methods to minimize defects. Preliminary results suggest that certain structural designs can reduce issues, highlighting the need for further research on geometrical features and manufacturing precision in SLM.
