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.
Claims18
A composition for three-dimensional metal fabrication, said composition comprising:
- metal powder, whereas said metal powder has a melting point above 400.degree.;
- and
- a temperature equalization and unification vehicle mixed with said metal powder to form a mixture, wherein a thin layer of said mixture may be irradiated to melt the metal powder and form a metal film.
