Also called: Multi Jet Fusion
MJF (Multi Jet Fusion) spreads nylon powder, sprays fusing agents where the part should be, and applies heat to fuse each layer. Like SLS, the powder supports the part, so no support structures are needed.

Nylon PA12 (SLS / MJF) · Nylon PA11 (SLS / MJF) · TPU powder (SLS / MJF)

MJF or SLS? Both make strong nylon parts. MJF is often faster for batches with a slightly finer finish; SLS may offer more material choices. Either is a good option.
