Abstract: A curable, optical ink comprises first and second monomer monomers. The first monomer is photopolymerizable over a first wavelength band. The multifunctional second monomer is photopolymerizable over a second wavelength band, which is distinct from the first wavelength band.

Abstract: An aqueous or organic solvent medium for additive manufacturing technologies comprising a nanocrystal comprising a functional group. The nanocrystal material is selected from a metal oxide, fluoride, metallic, carbon-based, semiconducting quantum dot or combinations thereof. The functional group comprises primary amine, carboxylic acid, lactam ring, polyamide polymer chain or group used to attach a similar functional group.

Abstract: The present disclosure discloses an optical ink matrix comprising a UV polymerizable monomer, at least a first multifunctional monomer. The optical ink matrix may further comprise a second multifunctional monomer. The present disclosure further discloses a method of manufacturing non-axially symmetric GRIN lens using 3D printing.

Abstract: A method of additively manufacturing a composite article with tuned impedance and refractive-index in three dimensions. The method includes providing a ferrite feedstock. The ferrite feedstock is loaded with ferrite particles. The method further includes depositing and curing the ferrite feedstock. Therein a composite article is formed.

Abstract: A method of bonding an RE:XAB gain medium to a heat spreader includes using a bonding solution of sodium silicate with concentration of sodium silicate is Na2O at 21.2% and SiO2 at 53% with PH>=11 mixed with nano-pure water in a 1:1 ration. Applying the bonding solution onto either a surface of the RE:XAB or a surface of the heat spreader, aligning the RE:XAB and the heat spreader, applying pressure to draw the surfaces of the RE:XAB gain medium and the heat spreader together thereby uniformly spreading the bonding solution; and then curing the bonding solution.
