Understanding the HP Multi Jet Fusion Process
HP’s Multi Jet Fusion (MJF) technology stands as one of the most innovative advancements in 3D printing. This technique employs a two-fluid system during the printing process: one fluid acts as a thermal conductor, while the other serves as a thermal retardant. The thermal conductor adheres to the main body of the print, whereas the inhibitor is applied to the periphery. Subsequently, infrared energy sources apply heat to fuse the layers above the print bed, resulting in precise and cohesive structures. Developed between 2014 and 2016, this method has gained significant traction in the realm of additive manufacturing.
