well depending on speed and print plate material. I find that for 90% of pla prints 200c and 65c build plate work across the board - on all my machines and pretty much all the build surfaces I've used over the years..

But as I've been playing with some pet-g today - got to say I am confused lol

Prints great at near enough pla speeds - which apparently it should not. Very clean prints, no webbing or spiking - again, apparently not what it usually does.
I'm currently down to 50c for the build plate to try and offset too much 'stick'.
And I've been orinting with the cooling fan on 100% from layer 2 onwards.

Pretty much all things the entire internet will tell you will not work with pet-g.

So yeah - there is no substitute for individual experimentation.

I will say that pla is a lot stronger than this pet-g, also a LOT harder.
What the pet-g does have is 'toughness'. Much the same as nylon.
ie: uit has abit more 'give'. So would be better for things like pond fittings or anything that needed a little bit of flex.
Currently I make all our custom pond fittings from stiffish flexible pla.
But next time we need so,ething I think I'll give pet-g a go.

But yeah - been an interesting days experimentation.
