Not the person you’re replying to, but I can see the appeal of PLA. It has more color options and prints way easier.

I personally run all PETG because it is ultimately better material post-print, and once you understand how to print with it, it’s not really much harder to deal with.

The day I discovered that I should just run my dryer with the PETG inside while printing was revolutionary. Of course, that requires you own a dryer that allows the filament to print while it’s inside.

I wish I knew how to dial in PETG fully. It prints fine for me but I still get globbing and stringing so the surface finish just isn’t that amazing.

That's definitely still where I see the appeal of PLA, and once I get through the too much bulk PETG that I own I may mix up my future purchases to have more PLA where I don't need load strength and won't have issues with high temperature usage.

I am getting reasonably consistent prints but they aren't perfect.

The long version of my tips for using PETG are:

- A Bambu Lab printer doesn't hurt since it's so nicely calibrated and idiot-proof

- Clean the build plate with dish soap and dry fully. I haven't found any need for glue stick on a textured plate.

- Using a filament that has a profile available from the manufacturer for Bambu lab printers

- Printing with the filament in the dryer with the dryer running during printing

In my case PETG had issues until I realized that on my machine it needs to go slower.

I can print PLA at 100mm/s with .25mm layers...but PETG I don't go much over 65mm/s give the same line width/layer height.

Since getting things dialed in I switched to primarily printing PETG. Although, I have no issue printing PLA, PETG or ABS when needed.

I get some the appeal too but once you get a setup dialed in well and safely for ASA/ABS, theres rarely a reason to want to print either PLA or PETG.

Better ratio of weight to strength, far more durable parts for most jobs, and acetone smoothening opens up all sorts of doors to incredibly high quality prints without all the labor of sanding.
