Backstory: Like quite a lot of people here, I'm having problems with parts adhering to the build plate of a resin printer. I've tried everything that I can think of: cleaning & re-sanding the buildplate at 80 grit, levelling the plate with and without a sheet of paper between the plate and LCD, warm resin, and silicone spray on the FEP.
PRO TIP to improve bed adhesion: apply a thin layer of resin to the build platform before you start to print. I have not any failed prints after I started coating the plate with resin.
I was wondering if there was any clarification on this layer of resin:
- Should it be cured, partially cured, or left alone?
- How thick should it be?
Also, is there any known methodology? If I paint some resin onto the build plate and cure with a UV lamp, I worry that the layer won't be particularly flat. I thought about using the "cleaning" function on the printer to shine UV light through, but it would also cure area between the edge of the build plate and the tank.
Any tips on this exact method of making prints stick to the plate would be greatly appreciated!
I tried again, and it still didn't work.
I left a thin film of resin on the build plate from the previous failed print, and cured it for a minute or two until it felt tacky. The resin was still warm from last print, so I ran again (after removing the failed pancakes of course) and after a few hours I could see that nothing had printed this time either. The irritating bit is that the pancakes slide off the FEP pretty easily!
