Abstract: The invention relates to a device for mixing fluids and for producing a fluid mixture, including, a mixing chamber having a first inlet opening via which a first fluid can be introduced into the mixing chamber, a second inlet opening via which a second fluid can be introduced into the mixing chamber, and an outlet opening via which the fluid mixture including the first fluid and the second fluid can be discharged; a first supply unit, which is fluidically connected to the mixing chamber via the first inlet opening and is designed to carry the first fluid along a first fluid flow direction into the mixing chamber; and a second supply unit, which is fluidically connected to the mixing chamber via the second inlet opening and is designed to carry the second fluid along a second fluid flow direction into the mixing chamber.

Abstract: A method for providing manufacturing instructions for the powder-bed-based additive manufacturing of a component includes providing first irradiation vectors for a layer to be additively manufactured, which first irradiation vectors, upon appropriate irradiation by an energy beam, in particular a laser beam or electron beam, cause a porous structure of the layer, as well as providing the first irradiation vectors for a layer which is to be additively manufactured and which follows the layer, in such a way that paths of a porous structure of the layer and of the following layer at least partially overlap in order to allow for a flow through the manufactured component along a build-up direction.
