1. A method of manufacturing a tool part of a forming tool, the method comprising:
forming a tool element of the tool part having a shape-imparting operating face and at least one first cooling duct for cooling a liquid by additive manufacturing; and
inserting the tool element into a recess of a base element of the tool part such that the at least one first cooling duct is fluidly connected to a second cooling duct formed within the base element,
wherein the at least one first cooling duct has at least one rectifier portion including a blocking direction and an opposing passing direction, cooling liquid flowing through the at least one first cooling duct in the blocking direction has a higher flow resistance than cooling liquid flow through the at least one first cooling duct in the passing direction.
