Technology
Multijet Fusion (MJF) is an additive manufacturing technology that utilizes a high-resolution inkjet system to selectively fuse powdered materials, layer by layer, into complex three-dimensional objects. MJF is known for its speed, accuracy, and ability to produce functional parts with excellent mechanical properties. In MJF, a layer of powdered material is evenly spread across the build platform, and then inkjet printheads deposit a liquid binding agent in a pattern that corresponds to the desired part geometry. A heating element then fuses the material, creating a solid layer. This process is repeated layer by layer until the final part is complete.
