Our MJF 3D Printing Services

HLH Rapid offer Multi Jet Fusion (MJF) 3D printing services. HPs game changing 3D printing technology is a type of powder bed fusion system similar to SLS printing. The material is also a PA (Nylon) material and the technology produces great prototypes and functional parts. It is suitable for some of the most demanding applications. Black or full colour versions are available.

MJF Materials

PA 12

MJF PA12 or Nylon 12 can withstand drastic temperature drops, even staying strong in below freezing periods. It is characterized by high strength, stiffness, strong resistance to cracking under stress, and an excellent long-term constant behavior.

Typical MJF Finishing Options

Applicable MaterialsColourDescription
SandingAllBead blasting is a standard MJF 3D printing finish used to remove any remaining powder from the printed parts.
DyeingAllBlackDyeing is a fast and cost-effective way to colour MJF parts. It is mainly used to improve aesthetics.
Vapour SmoothingAllVapour smoothing is used to enhance mechanical properties and a part’s colour consistency and hue.

Design For MJF 3D Printing

HP MJF produces functional nylon parts with near-isotropic properties that can be used for detailed prototyping and end-use low-volume production. To take full advantage of this technology, learn to design assembly parts, wall thickness and more.

Advantages of MJF 3D Printing

MJF 3D printing can make a single part or component as easily as dozens
or hundreds of production pieces.

Complex Geometries
Geometries can be built more easily due to the 3D printing process,
adding complexity without additional cost.

Rapid Turnaround
Parts can typically be shipped in 3-4 days, allowing for faster design
iterations and speed to market.

Production Parts
MJF 3D Printing is capable of producing end-use parts with near-isotropic
properties on-demand, increasing throughput


Multi Jet Fusion or MJF is an additive manufacturing technology introduced

MJF builds parts by jetting a binding agent onto thin layers of polymer powder particles (typically nylon) and then sintering them using an IR heat source.

Multi Jet Fusion produces functional nylon parts, great for testing and low-volume end-use.

MJF and SLS are 3D printing technologies that both use powder PA (Nylon) materials. The main difference is the heat source. SLS uses a laser to fuse powder into solid parts. MJF, on the other hand, dispenses ink (fusing agent) on the powder then passes an infrared energy source to build the solid part. View the full comparison here.
