Multi Jet Fusion

What is the MJF process?

Multi Jet Fusion uses a thin layer of powder is first spread over the build platform where it is heated to a near-sintering temperature. A carriage with inkjet nozzles (which are similar to the nozzles used in desktop 2D printers) passes over the bed, depositing fusing agent on the powder. At the same time a detailing agent that inhibits sintering is printed near the edge of the part. A high-power IR energy source then passes over the build bed and sinters the areas where the fusing agent was dispensed while leaving the rest of the powder unaltered. The process repeats until all parts are complete.

Why use MJF?

1. Low-volume production of complex end-use parts

2. Prototypes for form, fit and function testing

3. Prototypes with mechanical properties to rival those of injection-moulded parts

4. Series of small components as a cost-effective alternative to injection moulding

5. Robust thermoplastic produces high-density parts with balanced property profiles and strong structures

6. Provides excellent chemical resistance to oils, greases, aliphatic hydrocarbons etc.

7. Ideal for complex assemblies, housings, enclosures, and watertight applications

8. Achieves watertight properties without any additional post-processing
