The quality of the finish of a Zortrax print is amazing. The Z Team did an outstanding job with this machine. But with such a fantastically smooth finish the current detail that the .4mm nozzle provides leaves you with wanting more. I understand the .4mm is a good compromise between speed and detail but would it be possible to support a .35 or smaller nozzle in the future?
I wouldn't hold my breath on getting different nozzle sizes as each size would require its own profile for each material - talk about a headache. With that said, if they do ever introduce the ultra-fine layer resolution it would be nice for them to develop at least one profile for a smaller nozzle (I'd vote UltraT) to go along with it.
