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.
Who TF is printing ABS with a bedslinger? I was talking about PLA & PETG. I never tried ABS, went straight to ASA on my enclosed printers since it’s less fumes and prints better.
It literally isn't.
A component overheats, fails, and stops being hot.
It does not create nearly enough energy to crwate an external fire.
Never has.
It's a reliability issue, but it's not a fire hazard.
If you think it is, you spend too much time on this sub.
There's a million A1s and a few hundred failures. It's rare, and only on a faulty batch.
It's solved moving forward, and they replace failed (and healthy!) boards for free.
Again, precisely zero actual fires. Go touch grass.
Zero fires.
Zero people injured.
Zero ability for it to generate enough energy to create an external fire.
I'm sorry you bought into the narrative that this rare, tiny fraction of a percent chance of a failure is in anyway an actual safety issue.
If it is, then prove it. It's your claim, the burden is yours, defend it.
The component that fails heats up, melts a spot of plastic, and dies, stops being hot. There has not been a single fire, as it fails exactly as designed to not be capable of starting a fire.
It's 99.98% reliable.
Million printers, few hundred failures.
I'm sorry you bought in to the reddit echo panic chamber on this issue.
It's been fixed moving forward, and they replace the ones for free from the bad batch as they appear. That's literally all there is to it. It's not the controversy that too-much-time-on-reddit would entice you to believe. Go touch grass and move on with your life. Jfc.
Probably people wanting to get into the hobby inexpensively. There's always going to be a market for a cheap entry point for newcomers and people who can't or don't want to spend as much.
The 8+ year old Creality Cr-10 series (300x300; 400x400; 500x500) could already do this. My Cr-10s could print ABS just fine, but it's obviously not optimal or easy as other materials.

Gotta be larger than 300x300 plate, at minimum?
I'm excited! My A1 is great, but I would love to go that little bit bigger on a few of my prints.
