Abstract
A stabilizer for inclusion in a photohardenable composition comprising a hardenable resin component and a photoinitiator, the stabilizer comprising a stable free radical functionalized polymer, wherein the stabilizer is dispersible or dissolvable in the hardenable resin component. A photohardenable composition including a hardenable resin component, a photoinitiator, and a stabilizer comprising a stable free radical functionalized polymer and methods including a photohardenable composition and products of the methods are also disclosed. A photohardenable composition can further include an upconverting component.
Claims21
A photohardenable composition for use in three-dimensional printing an object in a volume of the photohardenable composition, the composition comprising:
- (i) a hardenable resin component;
- (ii) a photoinitiator configured to create reactive species for initiating hardening of the photohardenable composition by free radical reactions when activated by radiation;
- and
- (iii) a stabilizer comprising a stable free radical-functionalized polymer, wherein the stable free radical-functionalized polymer comprises a polymer functionalized with one or more stable free radicals.
A stabilizer for inclusion in a photohardenable composition for three-dimensional printing an object in a volume of the photohardenable composition wherein the photohardenable composition comprises a hardenable resin component and a photoinitiator, the stabilizer comprising a stable free radical functionalized polymer, wherein the stable free radical-functionalized polymer comprises a polymer functionalized with at least one stable free radical, and wherein the stabilizer is dispersible or dissolvable in the hardenable resin component.
