Why is there not an official Bambulab PETG filament?

I don’t see any listed in the Bambulab store. Presently I’m buying 3rd party PETG and tweaking the generic PETG slicer profile, as presently that seems the only option.

Wham Bam suggests it’s because PETG sticks “too well” to the supplied sheets, which is why you are supposed to use glue stick as a release agent. But other PETG brands work fine.

@holmes4 Yeah, but those other PETG brands won’t have the RFID and the custom profiles already built into the slicer. I think the trend is more and more toward closed eco-systems, where you pay more for materials but everything “Just works”. That doesn’t exclude using matereials outside the ecosystem, but then you’re on your own in terms of tweaking profiles, unless, perhaps, people graciously share profiles among themselves. So far, I haven’t seen much of that happening.

me either and I have been trying to tune my petg profile little by little.

Anyone who has a good profile for Sunlu PETG, please post it here. :wink: Actually, I’m flexible on brand, so if anyone has any profile for some other brand, post that. I’m not picky!

I have not seen the need for tweaked filament-brand-specific profiles in my decade of 3D printing. I understand why Bambu has its own profiles because they tested their filament at the higher volumetric speed setting and can’t guarantee that random Chinese cat-walked-on-keyboard-brand generic filament can extrude that fast.

I’ve done some testing with PLA filaments I have on hand and created a profile with a higher volumetric rate that seems to still work fine. I haven’t done the detailed testing to see how high I can push it.

The PETG prints I’ve done at the generic PETG profile have looked great. I’ve also printed ASA and TPU with success.
