Resin film or residue with the prints

Good afternoon!

I'm having a little problem with my impressions. Every time I print a piece I realize that it comes with residue or resin films, which ends up making me spend more resin than necessary, but it does not harm my models.

This is normal? Is there anything I can do to improve the issue?

Thank you!

Have you filtered the resin between prints?

You could save a ton of resin by reducing the number of supports. Most of those u don't need.

I filter the resin every few uses, however the problem already starts from the second print. Should I filter it with every print?

Only need to filter if u have particles in the vat. When u say resin 'films' what do you mean by that?

Are you recharging and cleaning the vat window after every print?
When I finish a print, I remove the vat and place it on an angled surface so the resin settles below the window and the window is exposed. Before the next print I gently squeegee and wipe the window with a microfiber cloth that is lightly spritzed with Iso Alcohol. If it has been more than a few hours since the last print, I stir the resin in the vat (avoid the window while stirring!). That's it. I rarely need to filter the resin.

As RobertH said, you don't need all those supports. That said, all down-pointing (over 90 degree angle) elements must be supported and always preview the print after slicing to be sure everything is good. I suspect the first row of prongs are down-pointing because that is where the resin artifacts (film to you) are.

Good luck and Happy New Year!
