阅读说明：本技术 三维打印 (Three-dimensional printing ) 是由 K·瑙卡 T·安东尼 于 2017-10-30 设计创作，主要内容包括：在三维(3D)打印方法的一个实例中,施加金属构建材料。在金属构建材料的至少一部分上选择性施加包含金属盐的图案化流体。在施加附加的构建材料之前,使金属构建材料暴露于光照射以使金属盐达到热分解温度并热分解成金属。在暴露过程中,使金属构建材料保持低于金属构建材料的烧结温度。(In one example of a three-dimensional (3D) printing method, a metallic build material is applied. A patterning fluid comprising a metal salt is selectively applied over at least a portion of the metal build material. Prior to applying additional build material, the metal build material is exposed to light radiation to cause the metal salt to reach a thermal decomposition temperature and thermally decompose to metal. During the exposing, the metal build material is maintained below a sintering temperature of the metal build material.)
