An introduction to

Material Jetting (MJ)

Material Jetting (MJ) is a 3D printing process that works similarly to a 2D inkjet printer. However, instead of depositing ink, the printhead prints layers of liquid resin that are cured by a flashing UV light. MJ technology also uses wax supports that melt away in an oven for easy post-processing.

MJ, MJF, MJP, PJ – What’s the Difference?

Material Jetting (MJ), MultiJet Printing (MJP) and PolyJet Printing (PJP) all refer to the same 3D printing process. Material Jet Fusion (MJF) is similar, but uses a powder base solution versus resin. MultiJet Printing (MJP) is a proprietary technology from 3D Systems and PolyJet (PJ) is a proprietary technology by Stratasys.

MultiJet Printers (MJP)


ProJet MJP 2500Plus

Step up from desktop 3D printing to 24/7 usability and get more parts sooner to design better products faster. The ProJet MJP 2500 printers' industrial print head and optimized print parameters deliver up to 3 times faster print speeds than similar class printers for better efficiency and higher productivity.

ProJet MJP 5600

The ProJet MJP 5600 delivers ready-to-use parts at print speeds up to 2x faster than similar printers. This MultiJet 3D printing solution can quickly output a full build and offers a cleaning method that’s up to 4x faster than other processes thanks to automated post-processing. With a high capacity and over 50% larger build volume than other MultiJet Printing machines, you can print parts up to half a meter long—or several smaller parts—in a single build.


MultiJet Printing (MJP) materials include a wide range of functional, precision plastics, elastomeric, multi-material composites, and wax, enabling a broad set of applications for concept modeling, functional prototyping, rapid tooling, investment casting, and medical applications requiring biocompatibility.

Rigid – For MJP parts that look and feel like injection-molded parts, available in a variety of colors from white, black, clear, to gray and tan.

Elastomeric – High elongation and Shore A hardness make these materials great for MJP prototypes with rubber-like functionality.

Biocompatible – USP Class VI capable and/or compatible with ISO 10993 standards.

Multi-Material Composites – Print parts in single or several base materials, or mix multiple rigid and elastomeric materials to achieve custom performance characteristics.

Wax – Get the same melt and burn-out characteristics of standard casting waxes with VisiJet 100% wax 3D printing materials.
