Multi-jet fusion

In 2013, HP announced that they would enter the 3D printing market in 2014. In 2016, they introduced Multi Jet Fusion. In 2021, it was claimed that HP held around 100 patents related to MJF technology. == Operation ==

The printer distributes a powder (usually nylon) in thin layers over a build surface, and between each layer, two types of liquids, namely a fusing agent and a detailing agent, are sprayed onto the newly applied layer of powder using an inkjet. After the liquids are applied, a heat source (often infrared light) passes over the layer, which bonds the powder particles together into a solid layer. The next layer of powder is then applied on top of the previous one, and the process is repeated without the need for additional support structures since the surrounding powder provides the necessary support. Finally, the parts must be cooled and cleaned of excess powder. The result is claimed to often have better surface quality straight from the printer compared to fused filament fabrication (FFF). == See also ==
