Abstract
A kit for three-dimensional printing a metal object is described. The kit comprises a build material and a shaping composition. The build material comprises metallic particles. The shaping composition comprises a metallic mixture for forming an intermetallic compound with the metallic particles and/or that is exothermically reactive.
Claims11
A coated green body for preparing a metal object having an assembled part, the coated green body comprising:
- a green body having a three-dimensional shape that is defined by metallic particles and a binder;
- and
- a coating of a shaping composition on a surface of the green body at a region for forming the assembled part of the metal object;
- wherein the shaping composition comprises a metallic mixture for forming an intermetallic compound with the metallic particles or that is exothermically reactive, and wherein the coated green body has an initial shape arranged to self-assemble into a predetermined shape, which is a shape of the metal object.

A method of forming a metal object having an assembled part, the method comprising:
- defining a green body having a three-dimensional shape that is defined by metallic particles and a binder;
- selectively applying a shaping composition onto a surface of the green body at a region for forming the assembled part to produce a coated green body having an initial shape arranged to self-assemble into a predetermined shape of the metal object having the assembled part, wherein the shaping composition comprises a metallic mixture for forming an intermetallic compound with the metallic particles or that is exothermically reactive;
- and
- heating the shaping composition to react the metallic mixture to form the assembled part.
