- About Us
Here at GoProto, we’ve joined with HP to bring our customers the best in innovation as we leverage Multi Jet Fusion, or MJF. Glass bead-filled nylon allows for stiff and yet functional components that are fitting for a variety of industries: automotive, aerospace, medical devices, consumer products, and jigs/fixtures/assembly aids.
Parts are consistent, durable and production-grade.
Get stiff, functional parts with HP’s Multi Jet Fusion in Glass Bead-Filled Nylon
+ Designed for production of test and end-use, functional parts across a variety of industries (automotive, aerospace, medical devices, consumer products, jigs and fixtures).
+ Ideal for applications requiring high stiffness like enclosures and housings, fixtures and tooling.
+ Provides dimensional stability along with repeatability.
Quality and speed at a low cost per part
+ 40% glass bead filled thermoplastic material with optimal mechanical properties and high re-usability.
+ Jet Fusion technology produces parts faster than legacy processes like SLS.
Go with the pros at GoProto
+ The manufacturing experts at GoProto and HP have been working together over the past two years to study the metrology and fine-tune these game-changing printers. That unparalleled experience delivers strong, precise parts on time and to spec.
+ We recently moved and doubled our factory space and boast the 2nd largest Multi Jet Fusion capacity in the country along with our FDM and SLA capabilities.

Jesse Lea, the President of GoProto has put together a few short videos demonstrating Multi Jet Fusion’s capabilities. In fact, he goes on to say in the video –
“It’s very flexible and very capable…” – Jesse Lea | President of GoProto
MJF process & details: MJF is an additive process where parts are built layer-by-layer in PA12 Nylon or PA12 Glass Bead-Filled material, but unlike any process we’ve seen before. It’s a unique, hybrid methodology which employs a roller to first lay out a thin layer of granulated nylon on the print bed. The MJF printer then adds fusing and detailing agents via a large number of print nozzles at the Voxel (3d Pixel) level. Heat energy is then passed over the mix to fuse, cure and apply specifically-tailored mechanical properties. This is done in cross-section of the part layer by layer until the part is fully built up. The parts are then removed from the powder, cleaned, finished and inspected.
GoProto Services: GoProto continues to offer a vast array of conventional quick-turn manufacturing options, which have only been strengthened by the addition of MJF. Whether you need FDM or SLA, Machining or Sheet Metal, Tooling or Finishing, GoProto is your one-stop shop that will help solve your most complex engineering challenges.
