SLS vs MJF — two powder-bed nylon processes, different trade-offs.

SLS (Selective Laser Sintering) and MJF (HP Multi Jet Fusion) both produce production-grade nylon parts in a powder bed. They look similar in output, but the underlying physics are different — SLS uses a laser to fuse powder point by point, while MJF uses an inkjet head to deposit fusing agent across the entire layer at once. Those differences show up in surface finish, batch speed, and consistency. We run MJF because we believe it is the better fit for our production profile. Here is why.
