3D Printing Customized Optical Lens in Minutes.

ABSTRACT: Synergizing grayscale photopolymerization and meniscus coating processes, rapid 3D printing of optical lenses is reported previously using projection microstereolithography (PμSL) process. Despite its 14 000-fold-improved printing speed over the femtosecond 3D printing process, PμSL still consumes significant amount of the fabrication time for precise recoating 5 μm thick fresh resin layers. At the reported speed of 24.54 mm³ h^-1, 3D printing of the millimeter-size lenses still takes hours. To further improve the printing speed, the microcontinuous liquid interface production process is implemented to eliminate the time-consuming resin recoating step. However, the micrometer-size pores in the Teflon membrane needed for oxygen transportation are found to completely spo
