Some people print almost entirely with PETG, which makes a lot of sense to me.
My mentor, Dave says, "Honestly, I wouldn’t buy PLA but I would use it if someone gave it to me. There really is no need. PETG vs. PLA to me there is no difference."
To get started, I ordered two 1 kilo rolls. A roll of grey PLA by Overture, and a roll of blue PETG by Hatch Box.
Both companies are recommended. In particular, Hatch Box is recommended by my man Dave. I am diligently avoiding cheap filament (or trying to). It seems silly to "save" 5 or 10 dollars and have endless misery trying to print things.
The main thing seems to be that it requires a high nozzle temperature, on the order of 270C (260-310C). In general, this requires an all metal nozzle and will not be possible with all printers. Almost certainly my Ender 3 will not handle it. And almost certainly it doesn't matter -- I don't at this point have any burning need to work with polycarbonate.
