Multi-Jet Modelling (MJM) technology is a proprietary additive manufacturing method patented by 3D-systems and used in the line of professional ProJet™ printers. Models are built in layers using a printer head with several hundreds of nozzles. The MJM technology allows for simultaneous two-materials printing: in the build material (the photopolymer in this case) and in low melting point wax (used as a support filament for overhanging features). Each layer is exposed to the UV light for curing (solidification). After printing the model is placed in a special oven that melts and drains wax supports. The MJM technology allows to build accurate, high-definition models.

ProJet™ 3510 SD printer uses proprietary VisiJet materials: VisiJet M3 Crystal (build material) and VisiJet S300 (support material). It prints to a resolution of 375, 375, 790 dpi along X-, Y-, Z- axes respectively.
