Multi Jet Fusion (MJF) 3Technologie d'impression
| Aspect | Description |
|---|---|
| Technology Name | Multi Jet Fusion (MJF) |
| Developer | Hewlett-Packard (HP), introduced in 2016 |
| Process Type | Powder bed fusion technology using inkjet arrays to apply fusing and detailing agents, followed by infrared energy to melt materials layer by layer |
| Key Advantages | High printing speed (up to 10x faster than some technologies), high resolution (up to 1200 DPI), excellent mechanical properties, isotropic parts, and no support structures needed |
| Documents | Compatible with thermoplastics like Nylon 12, glass-filled Nylon 12, Nylon 11, polypropylene, and TPU elastomers |
| Applications | Functional prototypes, end-use parts in automotive, aérospatiale, santé, and consumer goods industries; ideal for complex geometries and lightweight components |
| Print Speed | Faster than Selective Laser Sintering (SLS), with overall printing speeds around 3 cm/h for full builds |
| Resolution/Precision | High detail resolution with smooth surface finishes; capable of producing fine features and complex internal structures |
| Restrictions | Limited material options compared to other technologies, high initial machinery costs, rough surface finishes requiring post-processing, and less economical for low-volume production |
| Notable Printers | HP Jet Fusion 4200, 540, et 340 series; printer prices range from $57,000 to $500,000 |
