Abstract:
Curable liquid nano-composites for additive manufacturing of lenses are provided. Methods of making the curable nano-composites, and methods of additive manufacturing using the nano-composites are also provided. Additionally, objects made from additive manufacturing using the curable nano-composites are provided. In one or more embodiments, the nano-composites can contain one or more cross-linkable monomers or oligomers; a photo-initiator; and a nanoparticle. In some embodiments the curable liquid nano-composite can have a viscosity prior to curing of about 1-150 cP at room temperature and pressure The curable nano-composite can be used for additive manufacturing by printing the curable nano-composite. The printed objects can include optical lenses such as both prescription and non-prescription ophthalmic lenses.
