#Filament less flexible than PETG with similar of better temperature resistance?

I have been struggling with Bambu PA6-GF since every larger print with a flat bottom warps a bit and I need the surface to be flat. I’ve tired nearly everything and while the warping is much better now, it isn’t completely gone. I will not purchase for this use again, not looking for advice on this filament.

Also don’t want to deal with annealing if at all possible, what I am printing is not mission critical but it needs to be stiffer than PETG and be able to resist temperatures inside a car or trunk in a Seattle summer. So PLA is out.

I’ve been considering PET-CF17 and PA612-CF15. The low warp property and lower recommended bed temps of the latter sounds appealing. Or would PETG-CF do the trick? I’ll be printing in an X1C. Any advice appreciated.

ASA is probably your best bet

Right, sorry but I should have mentioned that I don’t have a way to ventilate or filter as well as I would like and perhaps it’s a bit paranoid, but I try to avoid abs and asa.

PET and PA will both need to be annealed. Maybe PC will work for you?

I can’t get chamber temps high enough at a sustained level for PC, at least per Polymakers recs. If I don’t anneal and can settle for the properties of the PET or PA612 as is, wouldn’t they still meet the criteria I need?

No it's super soft. You can print PC in the X1, just takes extra effort

I added a little bit of ducting insulation to get better chamber temps. It helps quite a bit.
