Multi Jet Fusion (MJF) is HP’s proprietary 3D printing process. In MJF, parts are built by jetting a binding agent onto thin layers of polymer powder particles (typically nylon) and then sintering them using an IR heat source. MJF produces functional plastic parts with isotropic mechanical properties that can be used for detailed prototyping or end-use low-volume production.
In MJF, parts are built by jetting a binding agent onto thin layers of polymer powder particles (typically nylon) and then sintering them using an IR heat source. With a layer height of 80 microns, parts have high density and low porosity, compared to PA 12 parts produced with Laser Sintering.
Although new products continually emerge within additive manufacturing, outpacing the power of the original 3D printing systems developed in the mid-80s is still a challenging feat. Enter the mighty technology known as Multi Jet Fusion (MJF) though–built on the benefits and premises of previous conventional and 3D printing technologies.
