“…9,10,[24][25][26][27][28][29][30][31] Some custom setups [32][33][34][35][36] and modified commercial printers (Table S1; Note S1) provide spatial control over the exposure time to realize FGMs. However, this dynamic digital exposure method fails to be used extensively in commercial setups due to the difficulties of line-by-line G-code modification (i.e., to assign different exposure times for different regions in the same layer) 37 and its step-and-exposure process. 38,39 Herein, we present a halftoning grayscale printing method based on dithering and image-processing algorithms to fabricate FGMs by spatially controlling the polymerization degree of a photoresin (Scheme 1).…”

Functionally graded materials (FGMs) have spatial variations in structure or composition that result in gradients in their mechanical, thermal, swelling, or other properties. FGMs have garnered significant research interest because of their extensive applications in areas such as biomedical implants, sensors, and soft robotics. Recently, grayscale photopolymerization 3D printing has emerged as a promising technology for crafting complex and high‐resolution FGMs. This comprehensive work delves into various grayscale photopolymerization 3D printing techniques, offering insights into their ability to precisely control printing exposure energy and polymerization degree, which in turn influence material properties. Furthermore, this work highlights diverse applications of grayscale vat‐photopolymerization 3D printing. Finally, it offers perspectives on ways to enhance grayscale photopolymerization 3D printing, with a focus on improving printing feedstocks and grayscale strategies.
