I've been printing with PETG for a little while... using filament from eSun. It's no magic bullet. It's better than ABS in many ways, except that it's sticky and takes a while to cool which hampers many of it's positive attributes. I've really needed to work hard on the settings to get it to print well. The MicroSwiss all metal hotend has helped. I don't have to print so hot/slow... the new hotend seems to keep up better at the lower temp which means I can actually bridge something. It's strong and has some give. A decent material.

I'm now going to chuck a roll of eSuns ABS+ on. It's supposed to be like ABS but with less shrink/warp. I hope so... that's the only thing about ABS that really bothers me.
