Hi guys,
I am printing a complex part that is struggling to print without artefacts in PETG (even the CF) but is coming out very nicely in PLA-CF.
I am therefore considering this material despite not liking the low temp tolerance of PLA.
Has anyone put the PLA-CF to the test when it comes to temp resistance? Perhaps against regular PLA? If only it had a tad more temp resistance, it would be a much better material to produce with.
Any feedback on PLA-CF temp would be appreciated here!
Thanks!
Google has your answer! Basically it has slightly worse temperature resistance than regular PLA but is
variable by manufacturer.
Well i tested it - kind of. I used it for new rollers in my dishwasher. It didnt survive the 50C Program. Then i Printed it again with paht cf. Still good.
PLA is sort of biodegradable. It doesn’t degrade very fast by itself, you can’t just toss it in with your kitchen waste. But under the right conditions of temperature and humidity, bacteria can break it down very quickly. The threshold temp for processing waste PLA this way is something a little north of 50ºC I think (where the plastic becomes soft enough for the organisms to eat it), so soaking it in hot water is probably going to soften it up quite a bit faster than the temperature alone would…
There are lots of reports about the BBL PETG-CF filament being very difficult to print. I’ve never tried the BBL but I have had good luck with this Eryone filament.
That said, I think the use case for PETG-CF in general is non existent aside from the “carbon fiber look”. Regular PETG is great for things that need some bendability like snaps but you lose that when you add the carbon fiber.
ASA or ABS (with or without CF) is probably a better choice for what you are trying to achieve. ASA has become my favorite filament in the X1C as it prints as good as PLA but is much stronger, temp resistant and UV resistant.
If you need temp resistance and CF, they also offer PAHT-CF and PET-CF.
Hi guys,
Thanks for the replies! Much appreciated!
I have ordered a couple of rolls of ASA and will try and see how it goes.
I have considered the other high perf filament bambu offers, but it’s just too expensive for the part we are creating. It would not make financial sense.
What I like about the PETG-CF is the increased stiffness over regular PETG + the finish is nicer and it’s a bonus to have carbon in it, in terms of marketing.
Thanks again 
Hoping ASA can prove as consistent to print as PLA!
Bambu have a nice comparison PDF with all the filament specifications at
That’s a great comparison tool, thank you!
