    摘要: Methods of forming 3D printed metal objects and compositions for 3D printing are described herein. In an example, a method of forming a 3D printed metal object can comprise: (A): a build material comprising at least one metal being deposited; (B): a fusing agent being selectively jetted on the build material, the fusing agent comprising: (i) at least one hydrated metal salt having a dehydration temperature of from about 100° C. to about 250° C., and (ii) a carrier liquid comprising at least one surfactant and water; (C): the build material and the selectively jetted fusing agent being heated to a temperature of from about 100° C. to about 250° C. to: (a) remove the carrier liquid, (b) dehydrate the hydrated metal salt, and (c) bind the build material and the selectively jetted fusing agent; and (D): (A), (B), and (C) being repeated at least one time to form the 3D printed metal object.
