3D printing with light is enabled by the photochemistry underpinning it. Without fine control over our ability to photochemically gate covalent bond formation by the light at a certain wavelength and intensity, advanced photoresists with functions spanning from on-demand degradability, adaptability, rapid printing speeds and tailored functionality are impossible to design. Herein, we critically assess recent advances in photoresist design for light-driven 3D printing applications and provide …
