Abstract

Compounds and compositions are provided which are useful in additive printing, particularly additive printing techniques such as stereolithography (SLA) wherein a macromer is photopolymerized to form a manufactured article. Representative compounds comprise a polyaxial central core (CC) and 2-4 arms of the formula (A)-(B) or (B)-(A) extending from the central core, where at least one of the arms comprise a light-reactive functional group (Q) and (A) is the free-radical polymerization product from monomers selected from trimethylene carbonate (T) and ε-caprolactone (C), while (B) is the free-radical polymerization product from monomers selected from glycolide, lactide and ρ-dioxanone.
