Claim:
1. A device for producing or building up a metal part by laser sintering and melting, comprising: a generator for generating a laser beam; a means for deviating the beam to sweep the laser beam over a surface of the part to be produced; a sintering tray including a metal powder bed that can cover the surface of the part and that can be melted by the laser beam to increase a thickness of the part; and inductive heating means for heating the metal powder via induction, wherein the metal powder heated via induction is contained in a heating zone of the sintering tray, wherein said means for deviating the beam is configured to deviate the beam so as to melt said metal powder in said heating zone, and wherein said inductive heating means comprises inductors arranged around different heating zones of said powder bed contained in the sintering tray and vertically in a direction of the sintering tray.
