In the powder bed fusion (PBF) process, a 3D shape is formed by the continuous stacking of very fine powder layers using computer-aided design (CAD) modeling data, following which laser irradiation can be used to fuse the layers forming the desired product. In this method, the main process parameters for manufacturing the desired 3D products are laser power, laser speed, powder form, powder size, laminated thickness, and laser diameter. Stainless steel (STS) 316L exhibits excellent strength at high temperatures, and is also corrosion resistant. Due to this, it is widely used in various additive manufacturing processes, and in the production of corrosion-resistant components with complicated shapes. In this study, rectangular specimens have been manufactured using STS 316L powder via the PBF process. Further, the effect of heat treatment at 800 ℃ on the microstructure and hardness has been investigated.

Material is enabling technology that creates the product performance and the service of most industrial sectors and fields of technology. However, compared to the other fields such as IT, BT, and NT etc., relatively little attention has been paid to the research on strategy and innovation of materials technology. This bias should have resulted in the misfit of policy and less than enough investment in materials innovation. This paper discusses the characteristics, process, and future of the materials innovation. The process and status of materials technology in Korea are analyzed based on the discussions above. Finally, some suggestions for R＆D strategies of Korea are presented on the basis of the nature, trend and barriers of materials innovation.
