PETG Filament when resistance to cracking is necessary?

[Ward]

Just ordered two spools of eSUN PETG. I found PLA to work pretty d a r n good. Only complaint was it was just a bit brittle.
If PETG is any better I'm going to be in print heaven.

I got the PETG filament today and I printed a camera-holder, for first try, and it did Great !
(nozzle-temp @ 200C & bed-temp @ 70C)
I printed a camera-holder since it had a long bridge opening , about 36mm.
I wanted to see how well it did across gaps
and I was surprised how well it bridged the gap, with only one loose pass !
It seems very strong and flexible also.

I was surprised at the rough feel of the PETG filament, compared to other filaments,
almost like it has sand in it, but No problems out of nozzle !

Thanks for this update. Very helpful.

What printer was this on?

My PETG prints smooth, but then I use a nozzle temp of 245C (and fwiw, a bed temp of 80C).

My printer should be somewhere in Texas about now......4 more days before it gets here....rainy soggy day....sure wish I had it today

Our printer is a CTC-Bizer, as pictured in my avatar pic

I printed 2 more objects with the PETG @ 200C with no problems.
( that's actual temp, measured with calibrated digital thermometer)

The only minor problem I found was the Rough surface tends to make filament bind-up easier on the spool,
so have to watch it to make sure it does not.

I think I still like PLA filament the Best, for Most objects !

[ssayer]

For sure PLA is the easiest to print with. You'd never get an argument from me over that. It's always a matter of the, "what do you want to do with it?" thing, and almost all of the stuff that I print needs to take a little abuse. That's why I go with PETG most of the time.

Picking up some PETG tonight, really looking forward to playing around with it!

It'll be up on the site tonight for those interested.

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.
