Method for producing a component, and device

Abstract

A method for producing a component for a turbomachine, having the additive build-up of the component by an additive production method from a base material for the component and the introduction of material fibers into a construction for the component during the additive build-up in such a way that the material fibers are oriented in a circumferential direction of the component around a component axis and in such a way that a fiber composite material is produced, including the material fibers and a base material that is solidified by the additive build-up.
