Here is another request for feedback—this time, it’s about filtering resin tanks. For those of you who have needed to filter your resin tank, what has that experience been like?
How frequently do you find you need to filter your resin tank? After a failure? After only a very bad failure?
Do you find that some resins require filtration more than others?
What tools do you use to filter your resin? What is your process?
Please specify which printer you are using (Form 1, Form 1+, Form 2) and which resins you are using.
For me, I filter my resin using a DeKones 190 micron fine conical paint strainer with a plastic solo cup underneath. To get the resin completely out of the tank, I use a business card (which is just the right size for the resin spout on the Form 2 tank). When printing fine detail models in castable resin at 25µm, I filter after every dozen prints or so. For general purpose resins, I will only filter after a very bad failure. I had my first failure in many months today, when printing a solid part in grey resin with support touch points that were way too small.
