I've seen a few comments about it here and there in the forums but I'd like to dedicate a thread to it.
I've had mixed results with it and I'd like others opinions and experiences. Maybe even some help?
So here's my experience:
Creality Ender 3. Prints PLA wonderfully. For my first PETG prints I go with Amazon black PETG. I update my slicer with the higher temps and slow down my speeds. The stuff sticks to the bed just fine, and lays out well. Slight stringing compared to PLA but I expected that. The real problem was layer adhesion. I was printing something that was only a couple layers of wall thickness and when they were done, I couldn't even get them off the bed without falling apart. The snapped like a cracker. I had printed the same parts with amazon PLA and they were much stronger. So I certainly felt duped because PETG was supposed to be stronger than PLA. Printing specs were .2 layer height, 220-240C, 70C bed temp, 0-100% fan, 40mm print speed.
You can see in my print specs above some variables. I tried it all, different temps, different amounts of cooling fan, and even slowing it down to 40mm didn't help(I usually print PLA at 60mm). it was just like the layers wouldn't bond.
I did eventually have success with that same PETG on an XYZ cube at .01 and 50% infill. But that's a completely different animal than something with 2 layers wide walls.
