Claim 13:
14. The resin of claim 1, consisting essentially of:
(a) from 10 percent by weight to 80 percent by weight of (meth)acrylate terminated, bioresorbable, branched polyester oligomer; wherein said branched polyester oligomer comprises degradable ester linkages between constituents in an ABA block, BAB block, or AB random composition, where A is poly(lactide) or poly(lactide-co-glycolide), B is polycaprolactone or poly(caprolactone-co-lactide), and said oligomer has a molecular weight (Mn) of from 2 to 6 kilodaltons;
(b) from 5 percent by weight to 50 percent by weight of non-reactive diluent selected from the group consisting of N-methyl pyrrolidone (NMP) and propylene carbonate;
(c) from 0.2 percent by weight to 8 or 10 percent by weight of dihydro-4,4-dimethyl-2,3-furandione (DDFD) photoinitiator;
(d) an ultraviolet (UV) light absorber;
(e) optionally, from 1 percent by weight to 50 percent by weight of reactive diluent;
(f) optionally, from 1 percent by weight to 50 percent by weight of filler; and
(g) optionally, from 1 percent by weight to 10 percent by weight of additional crosslinking agent.
