Binder Jet additive manufacturing is a 3D printing technology that is used
for a variety of materials irrespective of the properties and characteristics. A variety of
materials that are used include ceramics, polymers and metals. The materials are
formed layer by layer by the adhesive bonding between material and binder. Compared
with recent developing modern manufacturing methods, binder jetting has the
capability of producing quickly integrated complex features for obtaining isotropic
properties. Green part manufacturing is processed to obtain the end part. Property
obtained through this process is close to the traditional powder metallurgy sintering
technique. This article discusses in detail the different materials used in binder jet
additive manufacturing, different process challenges involved, binder and droplets,
post-processing, characterization, the advantages and applications. Further, the powder
characteristics and process parameters are explained.
