The ProJet MJP 5500X 3D printer system is a Multi-Jet Printer (MJP) printer. The solid imaging 3D printer produces plastic prototype parts from 3D solid Computer-Aided Design (CAD) models and through the 3D printer system client software. The parts are generated in a rapid prototype (RP) environment. The primary features of the printer are the user interface, build chamber including the print engine, and the material delivery module (MDM), which contains the materials and waste bag.
