Abstract: In an example of a three-dimensional (3D) printing method, a crystalline or semi-crystalline build material is applied. A temperature of the crystalline or semi-crystalline build material is maintained within 100° C. below a melting point of the crystalline or semi-crystalline build material. A melt flow property reduction agent is applied to at least a portion of the crystalline or semi-crystalline build material, and the at least the portion of the crystalline or semi-crystalline build material in contact with the melt flow property reduction agent melts or coalesces at the temperature.
