Brittle prints.
Why are the prints so brittle after washing, drying and curing?
I use PRUSA Resin tough with 15seconds exposure time.

That is overexposed for this printer/resin combo. Most of the tough prusa resins are 6-7 seconds with a starting layer of 30 seconds. The manual 'highly recommends' sticking with the default presets.

RE: Brittle prints.
Are you still having trouble with the resin?
Differential expansion from very thick/solid walls can cause problems, so hollowing out models with meshmixer and putting in drain holes is important. Washing for too long can make the resin brittle too, supposedly. I have read in other forums some people get poor results from washing a long time (for hours in stead of minutes).
