Nah not really, all these failures were with original formlabs resins. 
I’m only switching now to cheaper resins as I am annoyed by how this was solved.
You think I wouldn’t know that after two years of usage. 
No, it’s not the solution. Read the topics on this forum. There is a problem with the galvo/laser itself. The beam changes shape after a year of usage. Formlabs charges 20%(800 something usd) to replace the galvo and laser. If it was just dirty optics, they wouldn’t replace it, right? Luckily my machine was within the EU warranty period but there are people who were less lucky.
