Dependent claims

A method for additively manufacturing a component, said method comprising:

depositing a heated thermoplastic material in at least one predefined surface area of the component;
and
solidifying said thermoplastic material by cooling, wherein at least one fiber reinforcement is inserted into the component by means of at least one supply apparatus, said fiber reinforcement comprising at least one pre-impregnated semi-finished textile product, wherein the fiber reinforcement is pre-impregnated with a thermoplastic material,
wherein said pre-impregnated semi-finished textile product comprises a fiber volume fraction of more than about 35% or more than about 40% or more than about 60%.
