Multi jet fusion is in a sense a combination of BJT and PBF-LB/P.
The parts of the powder bed that are supposed to fuse, are sprayed with black ink and the edges around it with a so called detailing agent. Then a high powered lamp is scanning over the powder bed. Since black powder absorbs more energy by the lamp, it is enough to melt it. The detailing agent keeps the black ink from seeping into neighboring sections and makes the melt pool very locally confined.
The print speed is comparable to PBF-LB/P but the cooling times are lower and powder recyclability is better. Regarding the ability to print fine details and mechanical properties, MJF has a slight edge over PBF-LB/P. But since MJF uses black color ink in the printing process, the parts are always grey or black in color, while for PBF-LB/P usually white powder is used, which can be dyed in any color.
