Abstract: 3D-printed blocks with drop coating could work as diffraction gratings while the layer stepping serves as the grooves of the gratings. This paper reports 3D-printed diffraction gratings coated with different resins. A ...

Abstract: The mask image projection-based stereolithography (MIP-SL) is a low-cost and high-resolution additive manufacturing (AM) process. However, the slow speed of part separation and resin refilling is the primary bottleneck ...
