Aspects of the present disclosure include methods for preparing crosslinked polydepsipeptide copolymers by stereolithography (e.g., 3-D printing). In practicing methods according to certain embodiments, a crosslinkable copolymer containing a depsipeptide having one or more hydrolysable crosslinkers is photocrosslinked by stereolithography to produce a crosslinked polydepsipeptide copolymer. In certain embodiments, methods include contacting the crosslinkable poly(depsipeptide-co-ε-caprolactone) copolymer precursor with one or more bioactive agents and photocrosslinking by 3-D printing to produce a crosslinked poly(depsipeptide-co-ε-caprolactone) copolymer with incorporated bioactive agent. Crosslinkable polydepsipeptide copolymer precursors and crosslinked polydepsipeptide copolymers are also described.
