Multi Jet Fusion (MJF) Prototypes

Building small, complex geometries use to take much longer.  Now HP Multi Jet Fusion (MJF) allows for faster builds, consistent surface finishes with undetectable layer lines. Whether used for producing single parts or batches of parts, MJF is a faster and more cost-effective process.

Multi Jet Fusion is a 3D printing process that produces functional nylon prototypes and end-use production parts. The final parts will exhibit fine feature resolution, quality surface finishes, and isotropic mechanical properties.

Multi Jet Fusion uses an inkjet array to dispense a fusing agent, and then a detailing agent across a nylon powder bed. The process starts with a layer of powder spread across the bed. The inkjet print head then sweeps across the powder bed depositing a fusing agent and then a detailing agent, ensuring that specific features come through and prevent thermal bleed. After more powder is dispersed onto the bed and the process repeats until the part is complete.

Once the build is complete, it gets transferred to processing. The part is processed to remove the loose powder. Then bead blasted to remove any additional residual powder.

Why Use Multi Jet Fusion (MJF)?

Multi Jet Fusion allows for thin layers and faster speeds than other technologies. The print head deposits both the material and the detailing agent in one pass, allowing the printing of multiple parts at once. MJF parts have a high density, low porosity, and an exceptionally smooth surface and need minimal post-production finishing. MJF produces highly accurate, detailed parts while maintaining the structural durability of traditional thermoplastics. MJF offers the ability to create a supported shape with overhangs; no secondary process to remove or dissolve supports is needed. Finally, MJF yields a higher percentage of powder recycled helping reduce end part costs. 

MJF is Ideal For: 

  • Low Volume Production 
  • Complex End-Use Parts 
  • Form, Fit, and Ready for Functional Testing Prototypes 
  • Quality, full-function parts.

We also provide consulting services for product development, engineering, and inspection & metrology.
