In article number 1705683 , Cheng Sun and co‐workers report a high‐speed 3D‐printing customized imaging lens of millimeter‐size. A significant increase in the fabricating speed is realized without compromising the dimensional accuracy and surface finish by employing highly parallel projection micro‐stereolithography and synergetic effects from grayscale photo‐polymerization and a meniscus equilibrium post‐curing process. This study opens new possibilities for rapid prototyping of freeform optics.
