Abstract

A method for producing a component provided with a supporting structure includes using at least one first laser for layer by layer manufacturing of the component out of a powdery material, using at least one second laser for producing a supporting structure, supporting the component, layer by layer out of the powdery material and operating the at least one first laser with a lower power than a power of the at least one second laser.

First claim

What is claimed is:

1. A method for producing a component and a supporting structure with a laser depositioning device, comprising:
providing a laser depositioning device with at least one first laser and at least one second laser;
using the at least one first laser for layer by layer manufacturing of the component out of a powdery material, and
using the at least one second laser for producing a supporting structure, supporting the component, layer by layer out of the powdery material,
operating the at least one first laser with a lower power than a power of the at least one second laser to:
produce the component with the at least one first laser at a lower rate of deposition and higher quality as compared to producing the supporting structure with the at least one second laser, and
produce the supporting structure with the at least one second laser at a higher rate of deposition and lower quality as compared to producing the supporting structure with the at least one first laser.

2. The method in accordance with claim 1 , and further comprising depositing a same coating thickness of the powdery material with each of the at least one first laser and the at least one second laser.

3. The method in accordance with claim 1 , and further comprising depositing a larger amount of the powdery material on the supporting structure with the at least one second laser than an amount of powdery material deposited on the component with the at least one first laser in a same amount of time.

4. The method in accordance with claim 1 , and further comprising providing that the power of the at least one first laser is smaller than the power of the at least one second laser by up to a factor of 5.

5. The method in accordance with claim 1 , and further comprising focusing the at least one first laser differently than the at least one second laser.
