Printing dynamic materials via 3D laser lithography

Light-driven 3D printing merges precision-controlled chemical reactions with intricate fabrication. Central to 3D printing are photoresists, which are light-sensitive materials that can undergo a distinct transforming under specific wavelengths. The advancement of light-driven 3D printing involves imparting adaptable behavior to printed structures, critical for erasing them post-printing. This erasing capability, achieved through judiciously designed photoresists with labile linkages, facilitates the removal of support materials, and for the degradation of cellular scaffolds. The presented work focuses on developing photoresists for 3D light-driven applications – utilizing light-stabilized dynamic materials – to fabricate degradable structures, showcasing a significant stride in this evolving technology.
