Multi Jet Fusion (MJF) is a 3D printing technology developed by Hewlett-Packard (HP) that uses fusing and detailing agents to create three-dimensional objects with high precision and strength.The MJF printer applies a powdered material, such as nylon, to a print bed, and a nozzle distributes the fusing and detailing agents over the corresponding areas of the 3D model.Next, a heat source (such as infrared lamps) is used to melt the powder, solidifying the desired shape.The process is repeated layer by layer until the object is completed.

MJF technology is prized for its ability to produce parts with fine details, complex geometries, generating products of excellent mechanical properties quickly and at low cost, without the need to generate substrates.It enables the idea of additive manufacturing on an industrial scale.
It is suitable for the production of functional prototypes, production components and custom objects.
