    摘要： Polymerizable liquids are described herein which, in some embodiments, can produce 3D printed articles of high resolution and desirable mechanical properties. In one aspect, a polymerizable liquid comprises an acrylate component, a polymeric additive, and a monomeric curing agent, wherein the acrylate component and monomeric curing agent are copolymerizable upon exposure to light. In being copolymerizable, the acrylate component and monomeric curing agent can form a copolymer. As described father herein, the monomeric curing agent can enable further reaction of the copolymer with one or more crosslinking species to link the copolymer with one more polymeric networks.

    摘要： In one aspect, inks for use with a 3D printer are described herein. In some embodiments, an ink comprises a polymerizable material and a reactive wax comprising a saturated alkyl moiety bonded to an ethyleneically unsaturated moiety through a urethane, urea, ester, or carbonate ester linkage, wherein the ink is free or substantially free of non-reactive wax.

    摘要： In one aspect, composite build materials for use with a 3D printing system are described herein. In some embodiments, a composite build material described herein comprises a carrier ink comprising a curable material; and pigment particles dispersed in the carrier ink, wherein the pigment particles comprise mica. In some cases, the carrier ink is present in the composite build material in an amount of about 80-98% by weight, and the curable material comprises one or more species of monomeric and/or oligomeric (meth)acrylates. Additionally, in some instances, the pigment particles are present in the composite build material in an amount of about 2-8% by weight and comprise up to about 85% by weight mica, based on the total weight of the pigment particles. The pigment particles, in some cases, can also comprise TiO2 and/or Fe2O3.
