HP Multi Jet Fusion (MJF)
Engineering-grade thermoplastics, optimized for 3D printing efficiency
An advanced 3D printing technology that excels in producing high-quality, complex parts quickly and cost-effectively.
Utilizing powdered thermoplastics, MJF stands out for its speed, achieving production rates up to 50 times faster than traditional methods. This technology is particularly beneficial for industries requiring precision and detail, making it a leading choice in the 3D printing market. The combination of speed, accuracy, and efficiency positions HP Multi Jet Fusion as a game-changer in additive manufacturing.
Fine detail and high dimensional accuracy

Produce strong quality parts
Robust thermoplastic that optimizes part quality with cost, producing strong structures
MJF = Multi Jet Fusion. It is a 3D printing technology developed by Hewlett-Packard (HP) for producing functional, durable parts.
How HP MJF works
Powder bed: A thin layer of nylon thermoplastic powder is spread across a build area.
Agent deposition: HP’s print head(s) selectively jet a fusing agent onto where the part should solidify and a detailing/contrast agent to fine-tune features.
Fusing: A high-intensity fusing lamp heats the laid-down areas where the fusing agent is present, causing those particles to fuse together.
Post-processing: After printing, excess powder is removed, and parts may require cleaning, curing, and any necessary finishing steps.
Why HP MJF is notable
Strength and durability: The parts are typically strong, functional, and suitable for end-use applications.
Fine detail and accuracy: Good resolution for complex geometries, smooth surfaces, and tight tolerances.
Material options: Primarily nylon-based materials (e.g., PA 12, PA 11, and variants with additives for different properties).
No support structures needed: The powder bed itself provides support, reducing the need for traditional tree-like supports.
Faster production for plastics: Often faster and more scalable for small to medium production runs compared to some other 3D printing methods.
Comparison to other technologies
FDM/FFF: Uses thermoplastic filaments; generally cheaper per machine but parts may be less durable and have more surface finishing work.
SLS (Selective Laser Sintering): Also uses powder, but a laser sinters the powder rather than using a fusing agent; MJF can offer faster print times and smoother surfaces in many cases.
DLP/SLA: High resolution for resin parts but usually for smaller, more detailed parts and often more brittle than nylon MJF parts.
Common applications
Prototyping with functional understanding (fit tests, ergonomics).
End-use parts for automotive, consumer electronics housings, housings, lightweight mechanical components.
Jigs, fixtures, and tooling made from durable nylon.
Material properties: Nylon PA 12 is common; consider impact resistance, temperature resistance, and wear.
Cost: Material costs and print time; MJF can be cost-effective for medium volumes.
Finishing needs: Post-processing steps like bead blasting, smoothing, or dyeing may be relevant depending on the project.
Produce strong quality parts
Ideal for complex assemblies, housings, enclosures and connectors
