Multi Jet Fusion (MJF) is a industrial power bed fusion 3D printing technology that chemically melts powder together to create strong, precise and detailed parts. Primarily used for end-use manufacturing thanks to its speed, MJF is a highly cost-effective solution for low to medium volume production. It eliminates the need for expensive tooling and enables production flexibility, allowing for cost-efficient customization and batch production. This cost-effectiveness makes MJF economically viable for various industries, including automotive, aerospace, consumer goods, and healthcare.

Multi-Jet Fusion builds parts by spreading a thin layer of powdered material across a build platform. Multiple jets then apply two types of liquid agents onto the powdered bed: the fusing agent and the detailing agent. The fusing agent is selectively applied to the areas where the part is to be formed. It helps bind the powder particles together during the subsequent heating process. The detailing agent is applied to the areas requiring fine details and features, enhancing the resolution of the printed part. After the agents are applied, a heating unit passes over the powdered bed causing it to melt and bond the powder particles together. The build chamber is then rapidly cooled to solidify the fused powder and maintain its shape and integrity. This process is repeated for subsequent layers, with a new layer of powder spread and the agents applied according to the digital design specifications.
