Multi Jet Fusion 3D printing is a powder-based technique, much like Laser Sintering. But it doesn’t make use of lasers as SLS does. The machine’s powder bed is heated uniformly, but rather than employing a laser to selectively fuse particles, a fusing agent is blasted in certain areas.

A detailing chemical is then jetted after this to enhance the print’s resolution. The jetting material absorbs the heat and disperses it uniformly as infrared lights travel over the powder bed’s surface.
Polyamide Material
The substance polyamide (MJF) is a white, finely divided powder. Its natural finish is greyish and has a sandy appearance. The white polyamide powder is combined with the black ink used as a fusing agent to create the final hue, which is grey. Because of this, depending on the print, the final grey can have somewhat varying shadings. The printed models can be dyed black for a unified appearance. For models that need clear textures, surface features, or labelling, you should use polyamide (MJF). Additionally, it works well for intricate sections like latticework and hinges.

Difference between Multi Jet Fusion 3D Printing and SLS 3D Printing
Both Polyamides are fairly similar, yet distinct 3D printing outcomes can be obtained using different procedures. While polyamides (SLS) and (MJF) can both be utilised for comparable purposes, MJF offers a few advantages over SLS.
To begin with, Polyamide (MJF) prints have more isotropy and reduced porosity. The ideal material for finishing with a finer surface resolution is polyamide (MJF), which also permits designs with thinner walls.
How quick is MJF?
Yes, Multi Jet Fusion 3D printing may be quicker than laser sintering technology. One of the reasons for this is that timing can be more predictable because printing each layer takes the same amount of time regardless of the build’s size or shape. This makes sense because with MJF technology, each layer of the print bed is fused all at once. In contrast, SLS outlines the model using a laser scan.
The fact that MJF needs less cool-down time than SLS—just 10 hours as opposed to SLS’s 24 hours—is another factor contributing to production timelines being quicker.
In conclusion, MJF is the technology to choose if you require shorter lead times, however Polyamide (SLS) is the greatest choice for coloured finishes since MJF is always grey or black.
