I am using white resin V4 for a year now printing hundreds of dental models with normal tank, directly on platform. Never ever had an issue.
Today I tried Model Resin V2, and my new LT Tank. I printed 3 models (two separate prints) and got the result you see at the photos. The tank seems worn off at both sides left and right but when I installed it it was pristine clear!
p.s. As I mentioned never had an issue with normal tanks, and white resin before so it is not by any chance an issue that has to do with printing directly on platform, I had only successful prints with my previous set up.
Thank you in advance,
