This Vat has been used for only half a liter of print and I am already having print failures due to clouding.
To me, it is evident that the vertical supports concentrate the wear in “failure triggering spots”.
See how they diffract the sunlight ? Well they do exactly the same with the laser’s light :
I’m not sure if the new Vat will also be affected by this, but if that’s the case, smarter inclined supports would make it’s life span not just 20, but maybe 30x or 40x better than baseline !
