Claim:
1. A metal powder processing equipment for use with a chamber having a table therein, in which metal powder is sequentially laminated on the table inside the chamber and laser beam melting or electron beam melting is performed, or cutting and shaping are performed by a rotating tool subsequent to the melting, comprising: a first temperature adjusting unit adapted to be placed at a lower bottom portion of the table; and a second temperature adjusting unit adapted to adjust temperature at all outer walls of the chamber and adapted to be disposed in contact with said outer walls around an outside of the chamber, wherein both the first and the second temperature adjusting units are adapted to be simultaneously heated or cooled, wherein the chamber is disposed out of a room, and wherein the room is configured to enclose an area including a metal powder reserve tank and a metal powder supply pipe except for a protruded portion thereof for supplying metal powder to a metal powder supply unit so as to cause the metal powder to fall into the chamber, and further comprising a third temperature adjusting unit adapted to be disposed inside the room for adjusting a temperature of metal powder in the metal powder reserve tank and a temperature of metal powder in the metal powder supply pipe, with a temperature of the third temperature adjusting unit set equal to an average temperature of the second temperature adjusting unit to adjust the temperature at the outer walls of the chamber one of: when the second temperature adjusting unit adjusts the temperature at the outer walls of the chamber.
