Abstract
Direct fabrication of three-dimensional metal parts by irradiating a thin layer of a mixture of metal powder and temperature equalization and unification vehicle to melt the metal powder and form a solid metal film. The vehicle also protects the molten metal from oxidation. The metal powder can contain an elemental metal or several metals, the vehicle can be an organic resin or an amalgam, and the irradiation can be selectively applied by a YAG laser.
