PETG Filament when resistance to cracking is necessary?

[EagleSeven]

petg tends to not bridge well but i can see why at 200deg you are not having problems with that. its usually printed at 240-250. 200 deg is going to give you less than great layer adhesion. i have printed somewhere in the neighborhood of 50-60kg of esun petg. some is smooth and some has texture. never in all the spools have i had an issue with either type. all comes off the spool just fine. the texture is there to theoretically reduce friction in feed tubes by lowering the contact. i dont think it really matters much with hard plastics. ninjaflex and other flexibles usually need a slightly textured surface to feed properly. i got a report from esun that petg is now outselling abs.

Yes, I can see how the Rough surface of filament could Help it going thru extruder,
more friction at feed-gear should really help, also.

Seems to be Great layer-adhesion at 200C,
I do have it going a little slower when doing outer-walls, with a small size nozzle (.3mm).

Filament hung-up twice on this spool, so far, when it got trapped at outer edge of spool.

I like PETG Much Better than ABS !
I like Any filament Better than ABS ! LOL
