Anyone tell me exactly how this guy cracked his LCD ? what exactly happened and how .

I empty the resin through a paint filter every time.  Its the only safe way to print.
Takes 2 mins max.

I do not, I pour it into the vat through a filter--for me a lot less hassle than juggling the tray, the resin jug, and a filter that doesn't really fit the resin jug's opening.

 i use a funnel.
