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.
