What is binder jetting used for?
Binder Jetting is used in a variety of applications — including the manufacturing of full-color prototypes, large sand-casting cores and molds on the plastic/ceramic side and small, functional parts on the metal side. They can be listed in categories including furan binder (for sand casting applications), phenolic binder (for sand molds and cores), silicate binder (environmentally friendly, for sand molds and cores), and aqueous-based binder (for metals).
What is the process of binder jetting?
Binder jetting is the process of depositing a thin layer of a powered component into the build chamber, followed by the application of adhesive droplets by a print head to bind the particles together [43]. This creates the part layer by layer, and postprocessing may be required to complete the work. Among the most important characteristics of those parts is the fact that binder jet parts are isotropic, or equally strong in all directions. That hasn’t always been true for 3D printed parts.During the Binder-Jet printing process, fine metal powders are spread in thin layers inside a build box. The layer thickness can be 0. The layer thickness directly influences the resolution of the printed part. A system of print heads deposit binder material over the powder layer.
