- This paper presents the optics design for a microscale Selective Laser Sintering (μ-SLS) system that aims to allow large areas of nanoparticles be sintered simultaneously while still maintaining micrometer scale feature resolutions in order improve throughput additive manufacturing process. The is shown able sinter 2.3 mm by 1.3 area metal have been spread into ~400 nm thick layer with resolution ~3 μm single shot. optical this ~1.2 indicating only about 2-3 pixels are needed form good part. In addition, using presented paper, it estimated μ-SLS should achieve volumetric ~63 mm3/hr, making process one highest processes available today three-dimensional structures.
