Picaso 3D Designer printer utilizes FDM (Fused Deposition Modeling) technology, which is also known as FFF (Fused Filament Fabrication). This printer is produced by "NPP IIS" company. This company has been developing and producing 3D printers for mass market since 2011. FDM is a technology of additive manufacturing: building 3D-objects is done by applying consecutive layers of the material (ABS or PLA thermoplastic) so that they copy the keyline of the digital model. These layers appear by the extrusion of molten thermoplastic through the nozzle that is placed in the printer head along with heating element and extruder (plastic thread feeding device).  Plastic hardens right after the extrusion.

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.
