Like Selective Laser Sintering (SLS), Multi Jet Fusion (MJF) is a technology via which the components are manufactured using a powder-based process. Instead of a laser that partially fuses the powder particles together, the HP 3D printer uses a multi-agent process. The agents used ensure that the powder particles are precisely connected.

In the Multi Jet Fusion process, two different active ingredients are applied, layer by layer, to the material particles by means of a print head. A “fusing agent” (black, heat conducting) is applied to the areas to be melted, and a “detailing agent” (water-based, cooling), is applied to the contours. Immediately after application, each layer is heated with infrared light. The areas treated with the black agent are heated more strongly and fuse together. The cooling agent ensures the fusion process is precisely delineated and thus ensures exact edges.

Multi Jet Fusion

  • Is a cost-effective entry-level technology for series 3D printing
    (20% cheaper than selective laser sintering).
  • For series production with many identical, rather smaller components.
  • Achieves tolerances of ± 0.4 mm up to 100 mm and ± 0.4% with dimensions over 100 mm,
    series-optimized tolerance values of 0.25 can be achieved.
  • Due to the active ingredients used, the resulting components are gray and can be dyed black or painted in a wide range of colors.
  • These components require only minimal finishing.
  • For fast creation of functional parts.
  • For 3D printed components with high quality, strength and durability.
