Abstract: A method of manufacturing an injection mold includes providing a build plate. A plurality of layers of a material are printed onto the build plate so as to form a near net shape of an injection mold component. The near net shape of the injection mold component defines a first volumetric part cavity. Material is removed from each of the build plate and the plurality of layers so as to form a net shape of the injection mold component. The net shape defines a second volumetric part cavity. The build plate at least partially defines the net shape of the injection mold component.

Abstract: A system includes a controller, a pretreating machine, and an additive manufacturing machine. The pretreating machine is coupled to the controller. The pretreating machine includes a pretreater structured to form an interface layer on a component. The additive manufacturing machine is coupled to the controller. The additive manufacturing machine includes a material feed and a forming beam. The material feed is configured to selectively provide a first amount of material on the interface layer. The forming beam is configured to substantially melt the first amount of material, thereby forming a first layer of a first material deposit on the interface layer.
