Distinguish PLA from PETG filaments?

#1

Hi,

I am a bit sloppy so in my filament box there are many filament samples without proper labels… So what is the best/easiest way to distinguish PLA from PETG?

Cheers and Prost,
Carsten

I’d say try and print with it. If it’s printable about 180/190 it’s PLA, if not it’s probably PET

If it’s translucent it’s probably PET. If it’s brittle it’s probably PLA.
