Exploring Material Diversity and Performance in Multi Jet Fusion (MJF) Technology


Multi Jet Fusion (MJF) technology primarily employs thermoplastic materials, with nylon being one of the most commonly used. Nylon, specifically polyamide (PA) materials, is favored for its versatility, strength, and durability. Within MJF systems, powdered nylon is spread evenly across the build platform, forming a thin layer. The printing process begins as inkjet printheads selectively apply fusing and detailing agents onto the powdered bed according to the digital design. Subsequently, a heating element passes over the powder bed, causing the fusing agent to selectively melt and bond the nylon particles together in the desired areas. This process continues layer by layer until the entire part is formed.


Apart from nylon, MJF can accommodate other materials such as elastomers and thermoplastic polyurethanes (TPUs), expanding its applicability across various industries and applications. These materials offer different mechanical properties, allowing for tailored solutions depending on the specific requirements of the part being manufactured. Overall, the choice of material in MJF plays a crucial role in determining the final properties of the printed parts, including strength, flexibility, heat resistance, and surface finish.
