I’m looking for fire retardant filaments for outdoor use. There hasn’t been much discussion of this here since 2024. Does anyone have any recommendations? I’m fairly neutral on if it’s ASA or something else, but I’m hoping for something that is also UV resistant and tolerant of direct summer sun. UV isn’t a deal breaker, I can always cover with a UV-blocking paint.
Thanks!
Ive used This (PC-FR Polymaker) for some electrical enclosures.
I cant comment on the UV resistance, Ive only used it inside. But the fire resistant properties are pretty good, it has additives that make it self extinguishing.
The downside is how hard it is to print. It needs high chamber temps. A stock Bambu will struggle with printing it.
Out of curiosity, what is the specific use case?
