Hey Parsa
The high power the Uniz printer is capable of shooting out makes it very dangerous too! The photopolymerization is highly exothermic (means releases a lot of heat) process. And if you “overshoot” the resin it gets hot! At a point that the resin film gets soft and tears very easily… As you probably know already.
But it is not your fault!!! Here the only one to blame is Uniz. They did a powerful UV light system because of their cUDP (Continuous Uni-Directional Peeling)… a bunch of nonsense anyway! The idea behind was to overexpose and move the platform up while still photocuring. But a large amount of heat is generated that way. That’s why they build a “water-cooling” underneath the LCD panel. Dough, the idea seems to be good but is not working every time. Basically you have a printer that is overpriced overbuild and undersupported and under capable of advertised specifications.
Sorry, welcome to the club!
