Abstract

A method of additive manufacturing an object by applying metal layerwise on a base with an application device successively aligned with different processing zones in relation to the base includes locally applying liquid metal in a processing zone. The liquid metal solidifies in the processing zone and precise adjustment of local material properties of the object are controlled by influencing or controlling temperature development as a function of time of the solidified metal with at least one thermal influencing device aligned with the processing zone and fixed relative to the application device. The thermal influencing device is at least one of a heating device and a cooling device.
