What Is Jet Fusion 3D Printing

Last Updated on March 22, 2022 by Leizi

Being a popular 3D printing technique developed by HP company, MJF (Multi-jet Fusion)is often applied to make the parts for the devices of electronics and fixtures. It helps the companies from various areas to make prototypes with higher efficiency.

The material of MJF is plastic powder. The first step of MJF is jetting the fusing and refining agent on the powder bed with a specific area as the program sets. Then, the jetted areas will be melted by the heating system. After finishing this step, it would be covered by a new layer of plastic powder. Through multiple repetitions, you will get the 3D printing parts.

The following step is removing the extra and loose powder of the finished parts. To make them look better, you need to do bead blasting and dye on the finished printing parts.

The advantages of MJF 3D printing:

Compared to other 3D printing processes including SLS and FDM, there are many advantages of MJF 3D printing. It can produce printing components without any supporting structures. Therefore, you can apply it to make the components with a more complicated design. That’s why people would choose MJF 3D printing to do low-volume production.

In addition, the finished components by MJF 3D printing have a more smooth surface. It means that it needs less surface finish and its lead time would be much shorter than other 3D printing processings. The common materials for MJF 3D printing are PA12, TPU, PA12+GF.

The Ruitai team specializes in making printing parts by SLS and SLA. We are looking forward to adding MJF printers to our factory in the future. And we are also glad to receive your e-mails about our 3D printing service: emily@szrtmj.com
