I know it has been mentioned again however the only way to do it right is to measure the resin in the tank and compare it with the print that is about to be printed ( this amount of ml needed vs how much ml is on the tank).
The way it is done so far leads to wasting resin. I have bought 4lt of white resin, my last one is now almost depleted, and I have printed 2,5lt worth of prints so far. The discrepancy is substantial. !
p.s. I print dental models, so small prints each time, I imagine that in jewelry the discrepancy will be even more dramatic (printing even smaller prints each time).
