Binder jetting is another form of powder bed fusion, where a binder is sprayed onto the powder which holds the particles together like a glue. This forms no real connection between the small particles. To really get a part that can be functionally used it has to be cured and sintered. For that reason, it can be used for ceramic materials as well. One of the biggest advantages of binder jetting, is that the parts can be built without support structures, since there is no heat to dissipate and no stability to add because of internal stresses. A disadvantage is, that the mechanical properties are in general not as high as for laser or electron beam powder bed fusion. Binder jetting was originally developed at the MIT in the early 90s. but it took until 2010 until it was commercialized.
