MJP or MultiJet Printing is an inkjet printing process that uses piezo printhead technology to deposit either photocurable plastic resin or casting wax materials layer by layer.


think3D has one MJP ( Multi Jet Printing) machine in-house to produces micro-detail wax patterns with outstanding surface quality and extremely fine features, ideal for intricate direct investment casting applications, such as jewelry.


MJP is used to build parts, patterns and molds with fine feature detail to address a wide range of applications. These high-resolution printers are economical to own and operate and use a separate, meltable or dissolvable support material to make post-processing a breeze. Another big benefit is that removing support material is virtually a hands-free operation and allows even the most delicate features and complex internal cavities to be thoroughly cleaned without damage.

MJP printers offer the highest Z-direction resolution with layer thicknesses as low as 16 microns. In addition, selectable print modes allow the user to choose the best combination of resolution and print speed, so it’s easy to find a combination that meets your needs. Parts have smooth finish and can achieve accuracies rivaling SLA for many applications. Recent material advances have improved the durability of plastic materials and are now suitable for some end-use applications.

One nice point about MJP printers is that they are office compatible, using standard office electricity to provide convenient and affordable access to high-quality prototypes and indirect manufacturing aids. Office compatibility in concert with their capabilities make MJP printers ideal for direct investment casting applications in jewelry, dental, medical and aerospace applications where digital workflows provide significant time, labor, quality and cost advantages.

MJP wax printers also offer a digital drop-in alternative to traditional lost-wax casting processes, eliminating time consuming and costly process steps while utilizing traditional casting methods and materials. All in all, these printers can print virtually any geometry and provide scalable high-volume throughput.
