Technology

Multi Jet Fusion

Multi Jet Fusion combines the design freedom of 3D printing with high-performance materials and a consistently fast build time to offer an attractive alternative to injection molding. With no support structures needed and surfaces that require minimal post-processing, this technology is ideal for functional prototypes and small series of even complex end-use parts.

Discover applications of Multi Jet Fusion

Part for Quigley 3D printed in PA12 using Multi Jet Fusion with a chemically smoothed finish
The fine-grain PA 12 used for MJF produces parts with higher density and lower porosity than laser-sintered PA 12, allowing for detailed surfaces.
Avular drone, parts of which are printed using PA 12 (MJF)
Drone manufacturer Avular chose PA 12 (MJF) to produce high-quality, lightweight, on-demand parts for their custom-built mobile robots.
Shock absorber 3D printed in Ultrasint TPU90A-01
Printed using Multi Jet Fusion, Ultrasint TPU 90A-01 has high elongation at break, making it ideal for prototypes and end-use parts that need good shock absorption.
Black toy tractor wheel printed using Multi Jet Fusion, with a glossy surface
A chemical smoothing process can be used to achieve a sleek, glossy surface on parts printed using Multi Jet Fusion.
Example of a densely printed latticed cube, printed using Multi Jet Fusion
With no support structures needed, Multi Jet Fusion makes it possible to print complex structures that have isotropic mechanical properties.
