This short clip shows the metal 3D printing process using ExOne's exclusive binder jetting technology. To create functional, strong metal parts, a secondary process is recommended. In fact, the binder jetting 3D printing process is similar to how a 2D printer adds ink to paper. Sintering: After printing is complete, the parts are placed in a high temperature furnace, where the binder is burnt out and the remaining metal particles are sintered (bonded) together, resulting in parts with very low porosity. The process involves metal powder being bound using the polymer binding agent. It improves the digestibility of proteins and starches and destroys the anti nutritional factors in food. Build sizes can be as large as 2200 x 1200 x 600 mm. Binder Jetting (BJ) is one of seven Additive Manufacturing techniques in which a binding liquid is selectively deposited to join powder material to form a 3D part. Moreover, as the part shrinks during sintering, there here is friction between the plate of the furnace and the lower surface of the part, which may lead to warping. is also limiting for very thin wall thicknesses (less than 0.5mm) or very thick (upper than 3cm). Among the additive manufacturing technologies today, binder jetting is unique because it does not employ heat during the process like others to fuse the material. The binder acts as an adhesive between powder layers. These two processes are described below: Once the part has cured, it is removed and placed inside a hot furnace.
