HP Multi Jet Fusion, or MJF, is a new powder-based 3D printing process created by HP for scaling industrial printing volumes from prototype to production. MJF is a digital manufacturing platform for additive manufacturing which combines many of the current 3D printing technologies of Binder Jetting, PolyJet, and Selective Laser Sintering (SLS) to create strong prototype and production parts quickly.
This allows MJF to 3D print production-quality parts in nylon, as well as other materials, fast with an accurate and detailed part finish. In addition to production components, the MJF 3D printing process is good for durable prototypes, printed color parts, living hinges, fit, form and function parts and printed assemblies. The Technology House has the capabilities to manufacture 3D printed parts and prototypes with HP MJF technology for your projects. Parts are usually available in as little as 3-5 days.
HP MJF works by using an inkjet-style process to deposit fusing and detailing agents to control voxels that are then fused into a solid layer then repeated until the build is complete. After the build is complete, the build is cooled then transferred to a processing station for loose powder removal and recycling.
Similar to SLS, HP MJF additive manufacturing doesn’t require supports while printing, unlike fused deposition modeling (FDM) or stereolithography (SLA). Building without supports allows parts to be nested within the powder build chamber which increases build efficiencies by increasing build capacity, reducing material consumption and reducing labor intensive support removal.
In the end, HP MJF parts are production-ready and can be easily post-processed to match the final custom finish required for all different applications like industrial, consumer goods and automotive markets.
HP MJF 3D Printing Benefits
HP MJF Best Uses
HP MJF manufacturing builds parts using thermoplastic materials: Nylon PA11, Nylon PA12, Glass Filled Nylon, PP and TPU. The most popular material is Nylon PA12, which is available in white and gray. This thermoplastic produces high-density, complex parts that have excellent chemical resistance and dimensional accuracy. When printing white or gray PA12 parts, you’ll receive consistency, uniformity, and repeatability from your first part to your last. White PA12 is ideal for parts used in the medical and consumer goods industries and also those that require vibrant colors post-processing. All materials are sustainable as the process refreshes the powder with recycled powder to reduce production costs while keeping part properties. Learn more about the available MJF materials.
White parts can be custom finished to match your prototype or production needs using HP’s color printing, dyeing, vapor smoothing, painting, or plating.
The HP 5210 printer has a build volume measuring 380 x 284 x 380 mm (15” x 11.2” x 15”), which is large enough to cover most 3D-printed parts. The biggest benefit is that a full build will print in about a half day or less and can be packed full of all different parts without supports, making it prime for lots of prototypes or production projects. Parts larger than the build size can easily be sectioned to build-in pieces and then assembled in post-processing. The HP 5210 is set up for production with multiple cooling stations and a processing station so that the machine can continually run while parts are being cooled and post-processed outside the build chamber.
The HP Jet Fusion 5420W delivers white consistency, uniformity, and repeatability—part after part. Ideal for applications and markets that require engineering-grade white production parts, such as:
Post-processing, white parts provide a base for more vibrant colors and better light refraction. The HP 5420W’s build volume is 380 x 284 x 380 mm (15” x 11.2” x 15”) and it boasts predictable and consistent print time for any type of part with no support structures needed. This 3D-printing solution delivers top-quality parts with dimensional accuracy—all at low running costs.

I have partnered closely with TTH for over a year, and working with them has been a wonderful experience. Their entire team is always pleasant to work with, their project managers are incredibly knowledgeable, and their attention to quality and timeliness is best in class. I simply cannot recommend them highly enough for any project big or small.

Most of my 30 year career has been spent finding vendors that meet my Cost, Service, and Quality requirements. The number of suppliers that can meet those criteria for a sustainable period of time are few. TTH is one of those companies. The management team at TTH is always willing to work with us to improve efficiency and offer solutions that exceed our expectations. If you are looking for a partner, not just a supplier, the team at TTH will not disappoint.

See how we partnered with Vitamix and Carbon to redefine what's possible. We took a legacy, six-piece, injection-molded part design and turned it into a new, one-piece, 3D-printed part.
Our integrated approach to design, prototyping, and production allows you to bring your concept to market faster and more cost-effectively than virtually anyone else.
