Device for the production of at least one metal body using 3D printing

摘要

Device for producing at least one metal body (2) by means of 3D printing with at least one laser with a laser head (5), a material feed device (8) and a construction platform (1), characterized in that the construction platform (1) has a floor (1) a container for receiving a powder of metal particles and / or metal grains (3) to be introduced into the container in layers, and that the container has at least one wall (4), which is variable in height relative to the base (1), for receiving the layers introduced into the container Has metal particles and / or metal grains (3), the wall (4) being connected to at least one drive for height adjustment in such a way that the wall (4) projects beyond at least the respective layer of metal particles and / or metal grains (3) to be introduced so that the The laser head can be moved over the container in the x and y directions and that the height of the laser head (5) and the material feed device (8) relative to the floor (1) as a construction plan attform (1) of the container are guided.
