But how would that work? If I get warping on the A1 Mini already sometimes, I can't imagine how a bed this large without enclosure could perform without warping.
Hmm. Oftentimes when I try to print something that covers the whole or most of the printing area in one direction, for example boxes of varying sizes, I have the corners lifting off more or less, or the build plate lifting off instead.
(And I always make sure the plates are clean, for something large I often use the Supertack plate and / or large brims, and I also design my stuff with round corners). I accepted it as part of the material properties and process with a not enclosed printer, but since some people are writing that there shouldn't be warping with the A1 Mini I would be thankful for further tips.
I also have these problems with my enclosed printers (whether I’m printing enclosed or venting). It’s mostly just the science of how things cool and their thermal properties.
If you aren’t already, every so often clean with PLAIN Dawn branded soap (others may have additives that coat the surface) and let it air dry / use a microfiber towel.
Another good option is using Vision Miner nano polymer adhesive. It’s a build plate adhesive, and it works wonders. If you let the parts cool fully, it will last 10-15 prints worth at least. VM saved me from throwing my Ender 3 with glass plate out the window.
