Material Jetting is one of the processes available to build parts in an additive format. Material jetting 3D printers use a printhead that is similar to those found in paper inkjet printers, except that these printheads deposit droplets of material onto a build plate. In most cases, the material is photosensitive resin that will cure under ultraviolet light.

 .

In at least one case (XJet), the droplets are metal powders encased in a special liquid. The dimensional accuracy of parts made through material jetting are considered excellent–± 0.1% is typical–along with very good surface finish. Material jetting is used primarily for prototypes and to make tooling parts for manufacturing. Each vendor’s material jetting system uses a slightly different process. Thus, in general, the material that will go through the printhead is heated to a specific temperature to achieve the best viscosity. Then, the printhead moves over the build platform and […]
