Abstract
The application relates to a method for the additive manufacture of a product, wherein a melt is discharged via a 3D printing head and the melt is deposited in the form of a melt strand on a printing table to form the product, wherein the 3D printing head and/or the printing table are moved in space in accordance with a product-specific computer program. The application is characterised in that the melt is supplied to the 3D printing nozzle via a needle valve nozzle. For the additive manufacture of the product, a volumetric flow of melt is specified which is specified by the geometry of the melt strand to be deposited and the traverse rate of the 3D printing nozzle and/or the printing table. The nozzle needle is moved between the closed position and the open position in such a way that the specified volumetric flow is maintained during the additive manufacture of the product.
