Abstract
Provided herein photo-reactive inks, thermal-curable materials and objects (e.g., medical implants, scaffolds, devices, etc.) made therefrom, and methods of preparation and use thereof.
Claims38
A composition comprising:
- (a) an acrylated or methacrylated polymer;
- (b) a photoinitiator compound, wherein exposure to light of an appropriate wavelength results in formation of a first reactive species from the photoinitiator compound;
- (c) a thermal initiator compound, wherein exposure to heat results in in formation of a second reactive species from the thermal initiator compound;
- (d) a poly(L) lactic acid (PLLA);
- and
- (e) a contrast agent.
