1. A method of additively manufacturing a metallic object, the method comprising:
applying metal as a liquid and layerwise on a base using an application device aligned with a processing zone of the base, wherein the metal is applied locally on the processing zone and subsequently solidifies; and
controlling temperature of the metal as a function of time with at least one thermal influencing device aligned with the processing zone such that a localized microstructure and mechanical properties of the object are adjusted, wherein the at least one thermal influencing device and the application device are fastened to a carriage and fixed relative to one another during manufacture of the object.
 
16. A method of additive manufacturing a metallic object, the method comprising:
applying liquid metal layerwise on a base using an application device aligned successively with a plurality of processing zones of the base, wherein the liquid metal is applied locally and solidifies on each of the plurality of processing zones; and
controlling temperature of solidified metal on at least a subset of the plurality of processing zones as a function of time with at least one thermal influencing device aligned successively with the plurality of processing zones such that a localized microstructure and mechanical properties of the object are adjusted, wherein the at least one thermal influencing device and the application device are fastened to a carriage and fixed relative to one another during manufacture of the object.
 
19. A method of additive manufacturing a metallic object, the method comprising:
applying liquid metal layerwise onto a plurality of processing zones on a base using an application device aligned successively with the plurality of processing zones, wherein the liquid metal is applied locally and solidifies on each of the plurality of processing zones; and
controlling temperature of solidified metal on at least a subset of the plurality of processing zones as a function of time with a heating device and a cooling device aligned successively with the plurality of processing zones such that a localized microstructure and mechanical properties of the object are adjusted, wherein at least one thermal influencing device and the application device are fastened to a carriage and fixed relative to one another during manufacture of the object.
