What is Multi Jet Fusion?

Multi Jet Fusion (MJF) stands as a cutting-edge 3D printing method, renowned for its swift production of precise, intricate parts from powdered thermoplastics. With MJF, you gain access to components boasting exceptional tensile strength and fine feature detailing, making them a prime choice for intricate industrial applications. Originating from HP, this relatively recent 3D printing innovation excels in crafting functional prototypes and production parts characterized by uniform mechanical properties, rendering it indispensable for tasks demanding intricate geometries and impressive cosmetic and functional attributes.


MJF 3D Printing Materials

HP PA 12 (Nylon 12)

Gray, dyed black. Functional prototypes, complex assemblies, watertight applications.

Glass-filled HP PA 12

Gray.Enclosures, housings, cases, fixtures, structural parts, tooling.

MJF 3D Printing Finishes

As Printed

Typically white or stone gray, smooth surface, powder texture, without visible layers.

Dyed (black)

Dyed black by immersion in a warm color bath. The color penetration reaches a depth of about 0.5 mm and covers all surfaces.

MJF 3D Printing Advantages And Drawbacks



MJF 3D Printing Application

Concept Models

The speed and versatility of MJF let product developers create tough and detailed physical snapshots of their designs.

Rapid Prototyping

MJF can be used to create fully-functional prototypes, complete with moving parts, as well as all-in-one assemblies.

Direct Digital Manufacturing

The low price and speed of Multi Jet Fusion make it an ideal way to build large quantities of discrete or customized parts.

MJF 3D Printing FAQs

MJF was developed by Hewlett Packard (HP) and introduced in 2016, with the claim that it was capable of print speeds up to 10 times faster than other technologies, and could print up to 12,000 voxels per linear inch, per layer. Voxels are the 3D equivalent of pixels on a 2D printer.

Common MJF applications include housing for electrical components, jigs and fixtures for highly specific purposes, and mechanical assemblies or enclosures.
