I tried some testing with a .2 nozzle about six months ago with the same results, just more trouble than it is worth. A few good prints, but horribly slow, way too prone to clogging, and the Delta just did not seem to care for it. But after that I ran with a .3 nozzle for a very long time and had fantastic prints. On this printer .3 really works out nicely, especially with S3D and that profile (as long as you do not use the mag plate, stay with glass).
For running SLA prints it really is quite impressive that it can get that level of detail on these prints, many printers can not even come close.
