  Additive manufacturing processes, such as powder bed fusion of thermoplastic particulates, may be employed to form printed objects in a range of shapes. Formation of printed objects having various colors may sometimes be desirable. Thermoplastic particulates incorporating a color-changing material capable of forming different colors under specified activation conditions may impart different colors to a printed object. Such particulate compositions may comprise a plurality of thermoplastic particulates comprising a thermoplastic polymer and a color-changing material associated with the thermoplastic particulates, wherein the color-changing material is photochromic and thermochromic. Conjugated diynes, such as 10,12-pentacosadiynoic acid or a derivative thereof, may be particularly suitable color-changing materials having photochromic and thermochromic properties for forming a range of colors upon a printed object. Nanoparticles, particularly silica nanoparticles, associated with an outer surface of the thermoplastic particulates may enhance the brightness of the color obtained under various activation conditions and afford coloration permanence.

  快速成型制造工艺，如热塑性颗粒的粉末床熔融，可用于形成各种形状的印刷物体。有时可能需要形成具有各种颜色的印刷物体。含有变色材料的热塑性微粒能够在特定的活化条件下形成不同的颜色，从而为印刷物体赋予不同的颜色。这种微粒组合物可以由多个热塑性微粒组成，热塑性微粒包括热塑性聚合物和与热塑性微粒相关的变色材料，其中变色材料具有光致变色和热致变色功能。共轭二炔，如 10,12-五聚二炔酸或其衍生物，可能是特别合适的变色材料，具有光致变色和热致变色特性，可在印刷物体上形成一系列颜色。与热塑性微粒外表面相关联的纳米颗粒，特别是二氧化硅纳米颗粒，可以提高在各种活化条件下获得的颜色的亮度，并提供着色持久性。
