Abstract
The present disclosure provides curable compositions comprising one or more of photo-polymerizable monomers as reactive diluents, as well as polymeric materials formed from the curable compositions. Further provided herein are methods of producing the compositions and using the same for the fabrication of medical devices, such as orthodontic appliances.
Claims38
A curable composition for forming a medical device by additive manufacturing, comprising:
- an initiator;
- and
- a polymerizable monomer, wherein the polymerizable monomer is a substituted phenyl (meth)acrylate having a vapor pressure of at most about 12 Pa at 60° C., wherein at least one ortho position of the phenyl ring is substituted with a group comprising at least one heteroatom selected from N, O and S or a group comprising a silicon atom,
- wherein the content of the polymerizable monomer is such that the composition has a viscosity from 30 cP to 50,000 cP at a printing temperature.
