Abstract: A method for additive manufacturing a metal or ceramic part including forming a green metal or ceramic body having sacrificial supports present on at least one surface of the green body and placing the green body into a heating chamber such that the sacrificial supports support the green body. The green body is heated to remove a binder, forming a brown body. The brown body is sintered forming a metal or ceramic part, and the sacrificial supports are positioned to support the brown body during sintering. The sacrificial supports are then removed from the metal or ceramic part.

Abstract: One embodiment is a heat exchanger comprising a shell surrounding a first fluid plenum, a plurality of flow chamber walls positioned inside the shell, and a diffuser positioned inside the shell. The plurality of flow chamber walls: at least partially define a plurality of first fluid radial flow channels in flow communication with a first fluid inlet and the first fluid plenum, at least partially define a plurality of second fluid axial flow channels in flow communication with a second fluid inlet, and comprise an arcuate shape and arranged in an array to at least partially define arcuate shapes of the first fluid radial flow channels and the second fluid axial flow channels. The diffuser includes a diffuser surface at least partially defining a diffusion flow path from the first fluid inlet and the plurality of first fluid radial flow channels.
