Abstract Diffusion bonding solid-state additive manufacturing technology adopts the same idea as laminated objective manufacturing. Laminates fabricated by precision machining or chemical etching are aligned and diffusion bonded to form 3D complex structures. This forming method is the most mature solid-state additive manufacturing method in industrial applications. This paper reviews the key applications of the method for different materials in the fields of astronautics, aviation, nuclear, fine chemical industry, navigation, injection mold and etc. Furthermore, the development of diffusion bonding technology and equipment manufacturing in the future are forecasted.
