    摘要： A three-dimensional (3D) printing method includes applying a build material, including: a plurality of first reactive particles; a plurality of second reactive particles, the first and second reactive particles to react with each other upon contact there with; and a coating on i) the plurality of first reactive particles; or ii) the plurality of second reactive particles; or iii) both i) and ii). The coating is to isolate the plurality of first reactive from the plurality of second reactive particles. A fluid is selectively applied on a portion of the build material, the fluid disrupting the coating on the portion of the build material to render the first and second reactive particles in the portion of the build material in contact with each other. The contact initiates mutual reacting and fusing between the first and second reactive particles.

    摘要： An example of a pre-treatment fixing fluid for an offset coated medium includes calcium propionate, calcium pantothenate, tetraethylene glycol, a surfactant having an HLB less than 10, an acid, and a balance of water. The calcium propionate is present in an amount ranging from greater than 4.5 wt % to 8.0 wt %, the calcium pantothenate is present in an amount ranging from about 2.0 wt % to equal to or less than 15 wt %, and the surfactant is present in an amount ranging from about 0.01 wt % to about 1.0 wt %, each based on the total wt % of the pre-treatment fixing fluid. The acid is present in an amount sufficient to render the pH from about 4.0 to about 7.0.
