Abstract: Matrix-filled liquid radiation curable resin compositions for additive fabrication are described and claimed. Such resins include a cationically polymerizable component that is an aliphatic epoxide, a multifunctional (meth)acrylate component, a cationic photoinitiator, a free-radical photo initiator, and a matrix of inorganic fillers, wherein the matrix further constitutes prescribed ratios of at least one microparticle constituent and at least one nanoparticle constituent. Also described and claimed is a process for using the matrix-filled liquid radiation curable resins for additive fabrication to create three dimensional parts, and the three-dimensional parts made from the liquid radiation curable resins for additive fabrication.

Abstract: Radiation curable compositions for additive fabrication processes, the components cured therefrom, and their use in particle image velocimetry testing methods are described and claimed herein. Such compositions include compounds which induce free-radical polymerization, optionally compounds which induce cationic polymerization, a filler constituent, and a light absorbing component, wherein the compositions are configured to possess certain absorbance values at wavelengths commonly utilized in particle image velocimetry testing. In another embodiment, the compositions include a fluoroantimony-modified compound. Such compositions may be used in particle imaging velocimetry testing methods, wherein the test object utilized is created via additive fabrication and is of a substantially homogeneous construction.

Abstract: Described herein are thermoset compositions suitable for hybrid polymerization when processed via additive fabrication equipment utilizing sources of actinic radiation with peak spectral intensities in the UV and/or visible region containing a photoinitiating package, a cationically curable constituent, a free-radically curable component, and optionally, one or more additives. Such thermoset compositions preferably contain a Norrish Type I photoinitiator that is an alkyl-, aryl-, or acyl-substituted compound centered around a Group 14 atom, and further possesses specified ranges of ionization potential values with respect to its known triplet state. Also disclosed are methods of creating three-dimensional parts via additive fabrication processes utilizing sources of actinic radiation with peak spectral intensities in the UV and/or visible regions employing the claimed thermosetting compositions, along with the parts cured therefrom.

Abstract: Described herein is a method for coating optical fiber where the coating has been cured by application of a source of monochromatic actinic radiation, such as a light emitting diode, wherein the coating contains a urethane(meth)acrylate oligomer; a (meth)acrylate diluent monomer; a diluent monomer having an electron donating group adjacent to the vinyl group, such as a vinyl ether monomer; and a photoinitiator. Also described are compositions which are capable of undergoing photopolymerization when coated on an optical fiber and when irradiated by a light emitting diode (LED) with improved surface cure and reduced yellowing. Also described are the coated optical fibers produced by such processes and compositions.
