Abstract: An ink for a printer may include one or more latexes in an amount from about 0.1 wt % to about 15 wt %, one or more amines in an amount from about 0 wt % to about 2 wt %, and one or more pigments in an amount from about 0.5 wt % to about 8 wt %. The ink may also include four or more solvents that, in the aggregate, are present in an amount from about 10 wt % to about 50 wt %. The ink may further include one or more surfactants in an amount from about 0.001 wt % to about 3 wt %.

Abstract: A method to produce a polymer gel includes dissolving precursors in a solvent to form a precursor solution, the precursors including polymer precursors, a stable free radical, one or more initiating radicals, and one or more stable free radical control agents, and heating the precursor solution to a temperature of polymerization to produce a cross-linked gel. A dried polymer aerogel has a Brunauer-Emmett Teller (BET) surface area over 100 m2/g, porosity of greater than 10%, visible transparency greater than 20%, color rendering index of over 20%, and average pore size of less than 100 nm.

Abstract: A color three-dimensional (3D) printing system includes (1) a solid build ink for each of a plurality of colors, each solid build ink includes (a) a solid acrylate in an amount from about 40 to about 70 percent by weight, (b) a non-curable wax in an amount from about 10 to about 45 percent by weight, (c) a curable wax in an amount from about 1 to about 15 percent by weight, (d) a photoinitiator, and (e) a colorant; each solid build ink has a curing speed adjusted by a ratio of the non-curable wax to curable wax such that the initial curing speed and final hardness of each solid build ink is approximately the same for each of the plurality of colors, and (2) a support material includes the non-curable wax used in each build ink, the support material providing a scaffold for deposition of each build ink.
