1. A resin comprising:
a monomer of a crystallizable polymeric material, the crystallizable polymeric material having a melting temperature above 20° C.;
a monomer of an amorphous polymeric material, the amorphous polymeric material having a glass transition temperature less than 40° C.;
an initiator: and
a polymer crystal, said polymer crystal comprising the monomer of the crystallizable polymeric material,
wherein the resin has a viscosity from 0.5 PaS to 20 PaS at 90° C. and is capable of being 3D printed to form a 3D-printed polymeric material, wherein the 3D-printed polymeric material forms an orthodontic appliance.
