Multi Jet Fusion (MJF)

Reinvent How You Prototype and Produce Functional Parts

Ideal for mechanical testing and production manufacturing


Multi Jet Fusion

HP Multi Jet Fusion (MJF) technology offers high build quality at a much higher speed, and at the lowest cost, relative to competitive 3D printing solutions in the marketplace today.

What are the prime applications ?

Prime applications for 3D printing include the functional and aesthetic components of machines, consumer and industrial products that are manufactured in short and medium runs up to thousands of units. Before 3D printing, parts with complex surfaces, moving elements, and internal fluid passages were assembled from sub components that were aligned and assembled with fasteners and/or adhesives. In conventional parts—especially those designed to handle air and liquids—joints and sealing surfaces may be points where mechanical failure and leakage occurs. But, with 3D printing, complex parts can be produced either as a single piece or from far fewer sub components.

3D printing has the potential to simplify design and manufacturing processes and to reduce processing time and costs. Parts can be made by 3D printing that cannot be made by other methods, and this creates many new possibilities for innovations in design, form, and function.

What is the Digital Manufacturing Network (DMN) ?

The Digital Manufacturing Network (DMN) is a very select group of production-capable suppliers of Multi Jet Fusion parts, as certified by HP.

HP set a standard of very high quality in printed parts that DMN members must meet for solutions engineering, production capacity, consistency, quality and repeatability of prints.  HP audited all partners to also verify our stability as a company.

GoProto was selected by HP as one of the first six foundation partners globally that meets the very high standards of acceptability. HP selected GoProto as a foundation partner to deliver prototype and production parts in North America due to our customer-solutions orientation, production capacity, and decades-long relationship with the HP printing family.

As one of the first service bureaus to be selected in the country, we offer leading-edge expertise, and will help you get started with this groundbreaking manufacturing process. Whether you need quick-turn prototypes or more robust production parts, GoProto is your source for all things Multi Jet Fusion.

For true 3D Printing innovation, we help refine your product design to bring you to market faster. As an HP DMN partner, GoProto assisted Ropes Edge in producing a new safety device to protect life-supporting ropes from damage on sharp edges. We utilized HP’s Multi Jet Fusion (MJF) technology to sharpen Ropes Edge’s design and bring their product to market faster and cheaper than possible with traditional manufacturing methods.


“Hello America, I just want to let you know that the first MJF part arrived on time, was installed and tested and indeed solved our problem beautifully, and all exactly just in time. Thank you and your colleagues for your attention, speed, and quality. Well done.” — Keith (therapeutic medical company)
