You probably know about @Tom_Martz ’ T-glase already - do you use it on a regular basis or is it simply too expensive for you?
Need something that’s, like, really transparent? Don’t like the yellow tint natural PLA gives you, but still want something that’s easy to print? Then Taulman’s T-glase is the filament for you! https://www.youtube.com/watch?v=YI0FM_XdrzE
Have they fixed their spool size? I don’t buy any Taulman products because their small central spool hole requires a different setup than all other spools sold out there.
As far as i can tell, Taulman filaments are now sold on slimmer, larger spools. This particular one is still an old one, but I’ve got a few brand new spools coming in.
