well I've got items printed in standard pla that have been outside in the british weather for 3 or more years.
Apart from colour fading slightly, they're as good as new.
Bird feeders and poo bag dispensers primarily :-)

It's abs that doesn't like sunlight.

Not that we get much in the uk. But, cold, damp, rain and just plain misearable - we get a lot of that :-)

I have one pet-g item that is ridiculously strong. pretty sure it's esun white pet-g. It's a scraper I made to help change a motorhome awning.
Can't remember what settings I used. But even my dad couldn't break it and he's one of those people who looks on the term: 'virtually indestructible' as a challenge :-)

It's way tougher and stronger than injection moulded abs.
It was printed at 0.1mm layer height.
As were the miniature cogs i made a couple years back. That was colorfabb xt (they call it co-polymer, but I understand it's pet-g)

Everything I made in pet-g recently has been really bloody awful. Just weak as anything.

So I don' know if it's down to settings or my pet-g filament absorbing atmospheric water and getting 'wet'

Pet-g is more prone to stringing than pla.
Not a clue on your machine. Never had any type of i3 clone.
