It's risk warping and lift with PC (No enclosure!), or take the hit and print it on something that will hold it like the proverbial ".... to a blanket".
I've found the latter, but now have to find my way of taming it. I don't use glue sticks or hairsprays etc so far for anything, so finally may have found my match and have to, but it is a good starting point, Better to have than have not and need!.
I keep reading about reasons why your print won't adhere, but very rarely do I read about how to stop it adhering so well!.
I'm certain I can win this battle just by adjusting first layer height, temperature and speed and maybe come up with a lookup table of values for size and adhesion requirements, nothing more than a wipe with IPA between prints ideally as applying some sort of coating is so user dependant and availability of coating vs region.
It's like asking someone to spread butter on a slice of bread!, errmm, how much butter, what type, how thick etc....
