A method for the production of a shaped body and the use of an ultra short pulse laser for the production of a shaped body

摘要

A process for producing a shaped product consisting of a functioning as a support body and as a powder particles applied bodies through the selective connection of the powder particles with the carrier by means of laser beams, characterized in that, by irradiating the powder layer a thickness of less than / equal to 5 μm with a powder with a powder grain cross section of less than / equal to 1 μm with pulsed laser beams of high intensity of greater than / equal to 3 · 10¹⁵ W / m² in a vacuum or under inert gas up to a temperature lower than the melting point of the powder with simultaneous action of the radiation pressure of the laser beams of equal to / is greater than 100 bar, the powder and the carrier is selectively be connected by sintering without melt-phase component, wherein the shaped body is produced with microstructures.
