| 摘要 |
A process of making three-dimensional objects in a stepwise, layer by layer manner in which a build material (30) contains a metal having a covalent bon d to a non-metal, and the layers (40a, 40b, 40c) are processed to produce a three-dimensional object at least in part through a chemical reaction which alters the covalent bond of the metal. In a first aspect of the invention th e build material (30) includes a metal that is covalently bound to a polymeric precursor. In another aspect of the invention, the build material (30) includes a metal that is covalently bound to a first ligand. Following deposition of the build material (30), the first ligand undergoes a redox reaction with a second ligand, thereby breaking the covalent bond of the metal. In a more preferred embodiment, the first and second ligands react to form a gas, and the metal reacts to form a metal oxide. In yet another aspec t of the invention, multiple build materials (30) are employed to provide non- uniformities such as electrical, thermal and magnetic conduction paths, structural supports, chemical and wear resistant areas, and so forth.</SDOAB > |
