Abstract

A method for producing an electrical component via a 3D printing includes preparing a first layer which includes a valve metal powder, consolidating at least a portion of the valve metal powder of the first layer via a first selective irradiation with a laser, applying a second layer which includes the valve metal powder to the first layer, consolidating at least a portion of the valve metal powder of the second layer via a second selective irradiation with the laser so as to form a composite of the first layer and of the second layer, applying respective additional layers which include the valve metal powder to the composite, and consolidating at least a portion of the valve metal powder of the respective additional layers via a respective additional selective irradiation with the laser to thereby obtain the electrical component.
