Binder jet 3D printing—Process parameters, materials, properties, modeling, and challenges

As a non-beam-based additive manufacturing (AM) method, binder jet 3D printing (BJ3DP) is a process in which a liquid binder is jetted on layers of powdered materials, selectively joined, and then followed by densification process. Among AM technologies, binder jetting holds distinctive promise because of the possibility of rapid production of complex structures to achieve isotropic properties in the 3D printed samples. By taking advantage of traditional powder metallurgy, BJ3DP machines can produce prototypes in which material properties and surface finish are similar to those attained with traditional powder metallurgy. Various powdered materials have been 3D printed, but a typical challenge during BJ3DP is…
