Abstract Additive manufacturing (AM) of tissue scaffolds provides medical professionals and patients with personalized treatment options, which align with patients’ specific physiology and provide a more efficient and precise manufacturing process. Vat photopolymerization (VP) AM affords biocompatible, degradable, and high-resolution scaffolds capable of achieving specific pore sizes necessary for tissue regeneration. Earlier biodegradable, photoactive polymers for the VP platform usually require dissolution in a solvent or water, which often results in anisotropic shrinkage upon drying and inconsistencies in the final part geometry. This work describes a photoactive oligomeric precursor that eliminates the requirement for water or solvent during VP. Poly(lactide-co-glycolide) (PLGA) diacrylates with low number-average molecular weights (
