Abstract: Heat exchangers are manufactured by three-dimensional (3D) printers by printing subsequent layers of a material in a print direction. The heat exchangers include one or more tubes. The one or more tubes are configured to transport a fluid to be heated or cooled. Each of the one or more tubes defines a slope that is within a threshold angle of the print direction. The heat exchangers include a plurality of fins that are each configured to intersect with the one or more tubes while allowing fluid flow between the plurality of fins to heat or cool the fluid. Each fin of the plurality of fins defines a slope that is within a threshold angle of the print direction.
