So How Does It Work?

In a quick nutshell, Multi Jet Fusion is a powder bed technology where the printer reads your CAD file in very thin slices and prints them layer by layer. The printer lays down fusing and detailing agents in these cross sectional layers onto powdered nylon-based material and then passes high-intensity light over it to fuse the material wherever the ink was deposited. Where it was not deposited the powder is left unfused. The process is repeated layer-by-layer and when the build is done the build chamber is cooled and the parts can be removed from the powder, finished, inspected and shipped to you – fast!

What are the prime applications ?

Prime applications for 3D printing with MJF 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 with MJF, 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 with MJF, complex parts can be produced either as a single piece or from far fewer sub components.

3D printing with MJF has the potential to simplify design and manufacturing processes and to reduce processing time and costs. Parts can be made by 3D printing with MJF 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.

HP DMN Partner GoProto & Ropes Edge Produce Trusted Solution


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.

“Thank you guys so much! I’m not sure what you guys are doing over there or how you do it, but GoProto has been a saving grace for us recently when most shops are quoting 5 week+ long lead times. Keep it up!” — Dakota (Engineering Consulting Firm)
