Abstract
The present disclosure relates generally to curable resins, in particular dual-cure resins, and related methods for use in an additive fabrication (e.g., 3-dimensional printing) device.
Claims20
A dual-cure resin for use in additive manufacturing, comprising:
- a photo-curable component configured to cure when subjected to an effective amount of actinic radiation;
- and
- a secondary component comprising a plurality of encapsulants containing a first secondary precursor species, wherein the plurality of encapsulants are configured to degrade, when subjected to a degrading event, and release the first secondary precursor species for secondary curing.
A method of producing an additively-manufactured article, comprising:
- providing a dual-cure resin comprising a photo-curable component and a secondary component, the secondary component comprising a plurality of encapsulants containing a first secondary precursor species, the secondary component further comprising a second secondary precursor species;
- subjecting the photo-curable component to actinic radiation to produce a photo-cured polymer;
- subjecting the secondary component to a degrading event to degrade the plurality of encapsulants and release the first heat-curable precursor species;
- and
- reacting the first secondary precursor species with the second secondary precursor species to produce a secondary polymer,
- wherein the photo-cured polymer and the secondary polymer form an additively-manufactured article.
