The powder material can be metals, sands, or ceramics. Unlike LBM, the printing phase does not require manufacturing support. Most binder jetted parts require post-processing, which can significantly lengthen production times and introduce inaccuracies. Not always suitable for structural parts due to the use of binder material, Additional post-processing can add significant time to the overall process. It can be faster since only a small fraction of the total part volume must be dispensed through the print heads. 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. Starting from a good surface condition makes it easier to reach very low roughness levels with post-treatment steps. In Binder Jetting, a binder is selectively deposited onto a powder bed, bonding these areas together to form a solid part one layer at a time. In addition, the binder material is distributed simultaneously by a system consisting of multiple inkjet heads. In addition, coloured binders can be used to create full colour parts or prototypes.
