MJF – Multi Jet Fusion
An industrial 3D printing process for manufacturing durable plastic components
understand the process
How does the MJF process work?
Unlike the SLS process, Multi Jet Fusion does not use a laser. With MJF, functional plastic parts are produced layer by layer from plastic powder at high speed and with high precision. The layers are fused together through the application of heat.
This process is repeated until the part is fully built up. The surrounding, unfused powder serves as a natural support structure, allowing complex geometries to be created without the need for additional support structures.
Features & Benefits
Typical features of Multi Jet Fusion:
- high dimensional accuracy and reproducibility
- good mechanical strength
- consistent material properties in all directions
- cost-effective for medium to large quantities
MJF combines the flexibility of additive manufacturing with a level of quality suitable for near-series applications .
An overview of the benefits of Multi Jet Fusion:
- Consistent, high-quality components across all batches
- good mechanical properties in all directions
- No support structures are required, allowing for great design flexibility
- cost-effective for medium to large quantities
- suitable for functional components in real-world applications
Typical applications
The MJF process is primarily used for functional plastic components that must be able to withstand the stresses of real-world use.
Typical MJF applications:
- Mass-produced parts and small-batch production
- functional enclosures
- Spare parts in mechanical and plant engineering
- technical functional components
Multi Jet Fusion primarily uses engineering plastics, which are characterized by their excellent mechanical properties. PA12, PA12 ESD, and TPUare among the most popular materials in this category.
The choice of material depends on the load, the operating environment, and the required service life of the component.
