Abstract: An additive manufacturing machine includes an energy beam system situated in a fixed position relative to a reference plane coinciding with an expected location of a build plane, an energy beam system with an irradiation device configured to generate an energy beam and to direct the energy beam upon the build plane, and a position measurement system configured to determine a position of the build plane. A position measurement assembly includes one or more position sensors, and one or more mounting brackets configured to attach the one or more position sensors to an energy beam system of an additive manufacturing machine. The position measurement assembly is configured to determine a position of a build plane with the energy beam system situated in a fixed position relative to a reference plane coinciding with an expected location of the build plane.

Abstract: A heat exchanger and a method for additively manufacturing the heat exchanger are provided. The heat exchanger includes a plurality of fluid passageways that are formed by additive manufacturing methods which enable the formation of fluid passageways that are smaller in size, that have thinner walls, and that have complex and intricate heat exchanger features that were not possible using prior manufacturing methods. For example, the fluid passageways may be curvilinear and may include heat exchanging fins that are less than 0.01 inches thick and formed at a fin density of more than four heat exchanging fins per centimeter. In addition, the heat exchanging fins may be angled with respect to the walls of the fluid passageways and adjacent fins may be offset relative to each other.
