Multi Jet Fusion by HP

HP Multi Jet Fusion (MJF) produces functional plastic parts with isotropic mechanical properties for prototyping or end-use low-volume production.

What is HP Multi Jet Fusion (MJF) ?

HP MJF (Multi Jet Fusion) is a 3D printing technology developed by HP, that uses a combination of inkjet printing and thermal fusion to produce high-quality, functional plastic parts.

The process involves spreading a thin layer of nylon powder over a build platform, and then fusing it using a series of inkjet printheads that apply fusing and detailing agents to the powder. The fusing agent causes the powder to fuse together, creating a solid part, while the detailing agent is used to create fine details and textures on the surface of the part.

MJF produces high-quality, functional plastic parts with excellent dimensional accuracy, smooth surface finish, and isotropic mechanical properties. The parts are ideal for detailed prototyping or low-volume production, with applications in industries such as aerospace, automotive, medical, and consumer goods.

One of the key advantages of MJF is its ability to print multiple parts simultaneously, and to vary the properties of the part by adjusting the fusing and detailing agents used during the printing process. This allows for the production of complex parts with a range of properties, such as rigid and flexible sections or varying levels of transparency.

Overall, HP MJF is a versatile and cost-effective 3D printing technology that offers high-quality, functional parts with a range of properties, making it ideal for a variety of applications across a range of industries.

MJF Materials

Nylon PA12

An engineering grade thermoplastic for high-density parts with extreme dimensional accuracy and fine detail for functional prototyping and final parts. This strong thermoplastic is ideal for complex assemblies, lattice structures, housing, enclosures and connectors, and optimal for post finishing processes – has excellent chemical resistance to oils, greases, aliphatic hydrocarbons and alkalies.

Nylon PA12 GB

This 40% glass bead filled thermoplastic material produces stiff, functional parts. PA 12 GB has both optimal mechanical properties and high reusability, and provides dimensional stability. It’s ideal for functional applications requiring high stiffness like enclosures and housings, fixtures, and tooling across a variety of industries.

Nylon PA11

This thermoplastic delivers optimal mechanical properties, and is known for producing strong, ductile, functional parts. PA 11 also provides excellent chemical resistance and enhanced elongation-at-break. Ideal for impact resistance and ductility for prostheses, insoles, sports goods, snap fits, living hinges, and more.
