I think with FDM printing we need better quality or some sort of auto smoothing feature. SLA prints look really good, but it's a pain messing with resins. If FDM prints could look just as good as SLA, then we would be onto something. The progress I have personally seen in the last 2 years have been remarkable, however the quality of FDM prints ave not improved all that dramatically. I do look for this to change in the next couple of years though as competition is certainly heating up.
