Continuous Liquid Interface Stretching for Ultrahigh Speed 3D Printing

ABSTRACT Among additive manufacturing techniques, vat photopolymerization (VPP) enables high‐resolution fabrication but remains limited by slow layer‐by‐layer processing. Although continuous liquid interface production (CLIP) eliminates platform retraction by creating an oxygen‐permeable dead zone, it still relies on discrete vertical lifts and costly membranes. Here, we present a continuous and uninterrupted 3D printing strategy that achieves high‐resolution fabrication at a very high speed up to 360 mm h −1 , even on LCD devices with only a weak UV illumination of 3 mW cm −2 . This strategy only involves a common high rigidity release film and low‐surface‐energy resins, which can effectively reduce interfacial deformation and separation forces to enable the build platform to lift continuously at a high speed. These print speeds allow parts to be produced in several minutes instead of hours.
