Abstract
The present disclosure relates to photo-curable resins, and, more particularly, to 3D-printable, surface-eroding, acrylic anhydride-based resins, including both acrylated and methacrylated chemistries. In a preferred embodiment, the resins compositions are degradeable. The disclosure also provides methods of preparing the photo-curable resins and embodiments of degradeable objects comprised of the photo-curable resins.
Claims20
A photo-curable resin composition comprising:
- a methacrylated anhydride of formula (I)
- or an acrylated anhydride of formula (II)
- wherein X is a carbon, a C2-C12 alkane, or a C2-C12 alkene;
- and wherein n is an integer of 1 or more.
1 more element
A method of preparing a degradable three-dimensional object, the method comprising:
- providing a photo-curable resin composition comprising a methacrylated anhydride of formula (I)
- or an acrylated anhydride of formula (II)
- wherein X is a carbon, a C2-C12 alkane, or a C2-C12 alkene;
- and wherein n is an integer of 1 or more;
- and
- a photoinitiator;
- forming a two-dimensional or three-dimensional object from the composition;
- and
- exposing the object to light to cure the composition.
