Multi Jet Fusion is a powder-based technology but does not use lasers. The powder bed is heated uniformly at the outset. A fusing agent is jetted where particles need to be selectively molten, and a detailing agent is jetted around the contours to improve part resolution. While lamps pass over the surface of the powder bed, the jetted material captures the heat and helps distribute it evenly.

Multi Jet Fusion’s unique build style includes fusing and detailing agents within a powder-bed fusion process. The build begins with a thin layer of powdered material being deposited across the build platform. Droplets of fusing, detailing and transforming agents are applied along with thermal energy on top of the powdered material to define the part’s geometry and properties.

The process continues layer-by-layer until a complete part is formed. After the print is finished, the build unit with the material and parts are rolled onto a processing station for cooling and powder excavation.

Multi Jet Fusion is ideal for hidden parts like complex ductwork, connectors or non-cosmetic housings. The process produces parts with extremely fine details, exhibiting small intricacies in complex designs such as embossed text, small holes or living hinges.

When it comes to build, the core difference between Multi Jet Fusion and Laser Sintering is the heat source. LS uses as CO2 laser to sinter cross-sections, while MJF uses the fusing agent to promote the absorption of infrared light.

  • High production speed
  • High process/post process automation
  • Low-volume production of complex end-use parts
  • Prototypes for form, fit and function testing
  • Prototypes with mechanical properties to rival those of injection-molded parts
  • Series of small components as a cost-effective alternative to injection molding

PA 12 (MJF) :   

  • Polyamide
  • High density & low porosity
  • Lead time: 5 working days
  • Maximum part dimensions: 256 x 340 x 360 mm
Standard lead time Minimum of 5 working days, depending on part size, number of components and finishing degrees
Standard accuracy ±0.3% (with a lower limit on ± 0.3 mm)
Layer thickness 0.08 mm
Minimum wall thickness 1 mm, but living hinges are possible at 0.5 mm
Maximum build dimensions 256 x 340 x 360 mm
Dimensions are unlimited as components may be composed of several sub-parts.
Surface structure Unfinished parts typically have a smooth surface, without visible layers, and a stone-grey color. Multi Jet Fusion parts can be sandblasted and colored/impregnated.
