What is multi-jet fusion?
The HP multi-jet fusion 3D printer uses an advanced additive manufacturing process. It incorporates powdered thermoplastic material, liquid agent, and infrared energy to fuse components seamlessly with remarkable accuracy. Our additive manufacturing (AM) technicians expertly remove any excess powder from the pieces, preparing the parts for use or further refinement.
This technology is excellent at creating functional nylon prototypes and end-use parts. Its real strength lies in producing brackets, connectors, hinges, housings, and thin-wall ductwork with utmost precision. Multi-jet fusion is also a strong choice for applications requiring fluid or gas containment due to its excellent density and minimal porosity.
How does a multi-jet fusion printer work?
MJF allows us to deliver high-quality components with speed and reliability. The process is straightforward:
- It begins when our AM technician uploads your CAD file into the machine, where the software breaks it down layer by layer.
- The printer uses an inkjet array to apply both a fusing agent and a detailing agent across a nylon powder bed fused by heating elements.
- Once finished, a roller applies a new layer of powder onto the powder bed, and the process repeats. There is no need for support structures because the powder bed suspends the part.
- Upon completion of the build, the entire powder bed is removed and taken to a breakout station, where AM technicians remove the parts from the powder, brushing off the excess.
- All parts are placed into a container and blasted with a blasting medium to remove the remaining powder.
- Once post-processing is complete, the parts go to the finishing department.
Advantages of Multi-Jet Fusion
Multi-jet fusion technology has revolutionized the way products are designed and manufactured. This process offers many advantages, including:
- No support structures means efficient manufacturing.
- Production of high-density components suitable for demanding applications.
- Automated vapor smoothing is available to enhance surface finish and appearance.
- Fine feature resolution to meet precise engineering requirements.
Disadvantages of Multi-Jet Fusion
While there are many advantages, multi-jet fusion also has some disadvantages to consider:
- Finishing and post-processing are necessary to achieve smooth surfaces.
- Parts may be brittle.
- Components are not UV-resistant and can discolor.

Prototek's MJF Materials
At Prototek, we partner with our customers to find the right material for their application. Material selection is crucial in multi-jet 3D printing because it directly impacts your part’s properties, performance, and cost. We carefully consider factors like tensile strength, flexibility, and chemical resistance when recommending materials.
HP Nylon 12 is a high-performance MJF material with exceptional durability and versatility. Its chemical resistance and mechanical strength mean that parts made from this nylon powder can survive in harsh conditions without breaking or becoming misshapen.

MJF Design Recommendations
When designing parts for HP MJF, you must consider several critical factors to ensure the best possible outcome. Our designers will walk you through each step, helping you create functional parts optimized for production to meet the specific needs of your applications:
- Optimized designs: MJF printing is a powder-based manufacturing process, so the design should be optimized for this technique.
- Accurate specifications: It is essential to consider the effects of thermal expansion, which may cause slight changes in the dimensions of the final product as the powder material heats up during printing. Avoid overly thin wall thickness or delicate structures to prevent distortion and ensure that tolerances are specified correctly.
- Design efficiency: Lastly, designers should leverage MJF’s 3D printing technology benefits, including high resolution, fast build speed, and low post-processing requirements.
