  • Surface functionalization of inorganic nanocrystals for nanocomposite additive manufacturing
    Patent number: 11760644
    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.
    Type: Grant

  • ADDITIVE MANUFACTURE USING COMPOSITE MATERIAL ARRANGED WITHIN A MECHANICALLY ROBUST MATRIX
    Publication number: 20220134639
    Abstract: An additively manufactured article is assembled from a plurality of printed voxels. The article includes a lattice of unit cells of a composite lattice material and an encasing matrix of structural material arranged between adjacent unit cells of the lattice. The structural material has greater mechanical strength than the composite lattice material.
