MultiJet Printing (MJP) is a technology that builds objects layer by layer in a process known as additive manufacturing. These 3D printers use piezo printhead technology to deposit either photocurable plastic resin or casting wax materials layer by layer. MJP 3D printers can create parts with very high resolution. Layers can be as thin as 16 microns (about 1/6th the thickness of a human hair).This technology also offers meltable or dissolvable support material making post processing hands-free. This also allows thorough cleaning of delicate features and complex internal cavities without damage. The material used in MJP is UV-cured resin. The parts are strong and have a smooth finish making this a good option for prototyping, casting, and end-use parts. See also Ultraviolet (UV) Curing.
