I’ll believe it when I see it (printing) FFF or FDM are restricted due to the physical properties of the material being extruded and the properties of the extruder (inertia). You certainly pointed out some of these in the post but a tenfold jump in FDM seems unlikely to me. I am much more excited to see what is coming out of the SLA/DLP world myself right now particularly the Carbon3d and a couple of other recent risers. That is the space I will be investing in next.
