  • Patent number: 9574039
    Abstract: Photopolymer resin formulation for 3D printing enhancing the performance of 3D printed objects. In one example, additives comprising two photoinitiators with different absorption spectrums are used to achieve printing and post-curing processes. A thermal initiator can also be used to complete the post-curing process by baking at appropriate temperature. Additive combinations balanced to absorb some light in the near UV range of about 400 nm to about 420 nm absorption wavelength band or spectrum while fluorescing light at frequencies higher than their absorption wavelength allowing the creation of clear transparent materials using only near UV light sources (i.e., about 400 nm to about 420 nm) instead of deep UV (<400 nm) light sources.

  • Publication number: 20150056410
    Abstract: A process for application of metal on a substrate surface comprises applying a mixture of a solvent, a polymerizable monomer, and a photoinitiator on a substrate surface, wherein the photoinitiator does not form two phases together with the monomer and the solvent, i.e. it forms an amorphous mixture without any crystals. The monomer is able to polymerize to a polymer comprising at least one carboxylic group. Thereafter the solvent is evaporated. Polymerization is induced by irradiating the applied dried mixture. Ions are applied and reduced to metal and thereafter further metal can be deposited. The method can be used in industrial processes, both 2D and 3D surfaces can be coated with metal. Materials sensitive to standard grafting chemicals and/or polymers containing halogen atoms can be coated.

  • Publication number: 20140134349
    Abstract: The present invention describes a method for repairing defects on a surface of an optical substrate. The method includes a step of providing a radiation curable coating and then applying the coating onto a surface of the optical substrate. The coating is then cured with a UV light source causing the refractive index of the coating to be less than ±10% of the refractive index of the substrate. The cured coating exhibits a viscosity less than about 315 CP at 25° C. The present invention also describes a novel coating composition for repairing optical substrates.

  • Patent number: 8721844
    Abstract: Dental curing systems, apparatuses, and methods may include a light source, a perforated plate, and a dental composite. The perforated plate may be positioned between the light source and the dental composite. The perforated plate may include a plurality of perforations that convert a first curing light beam from the light source into multiple curing light beams before reaching the dental composite. The multiple curing light beams come in contact with the dental composite to begin the curing process at certain locations on the dental composite. The perforated plate may then be removed, and a second curing light beam from the light source may be applied to the dental composite to complete the curing process.
