Binder jet printing (BJP) is an additive manufacturing (AM) method which has the potential to be applied to high annual volumes in the automotive industry. Binder jet printing provides an excellent opportunity to innovate transmission valve body components. The three-layer design and complex hydraulic control system channels of valve body housing formulated a new electro-hydraulic system with the brand-new features inherited from BJP. For the valve body, the features of BJP brought a revolutionary new idea for both the valves and hydraulic channel design. The spool valve was housed with a sleeve that integrates orifices and port controls. The hydraulic channel layout of the valve body assembly was greatly simplified and space-saving. The support components had also been replaced with a lightweight design while maintaining the same functionality. Integrated design of Binder jet print produced hydraulic automatic valve system presented an entirely new design, whose static performance was compared to that of the conventional 948TE ZF9HP48 transmission valve body. Similar performance indicated that a valve body design featuring BJP would have great potential for various industrial applications.
