MJF Printing

About MJF

Multi Jet Fusion (MJF), developed by HP, represents a significant advancement in the field of 3D printing. This technology stands out for producing high-quality, functional parts faster than other 3D printing methods. MJF works by distributing a fine layer of powder material, which is then selectively fused together by applying a fusing agent and detailing agent, followed by applying heat.

How MJF Printing Works

In the MJF process, a thin layer of powder material (typically nylon) is first laid out on the printing bed. The printer then applies a fusing agent in the specific areas where the particles need to be bonded and a detailing agent around the contours to enhance definition and reduce bleeding. Infrared heat lamps pass over the surface, fusing the powdered material where the fusing agent has been applied, thus creating a solid layer. This process is repeated layer by layer until the entire object is printed. The unused powder acts as a support for the object, eliminating the need for additional support structures.
