Comment on PETG Print Issues

I would try with a brim, but I think it might be an issue with the design not having sufficient material at the base of those walls. The only way to tell is by looking at the sliced file layer by layer.

This is the sliced file and my attempt with supports.

A brim will help but the biggest thing is not to use fans at all during the first several layers and very sparingly after that. Also be sure your printer isn’t getting hit by a draft from an air vent or open window. PETG warps badly like this from too much cooling/temperature variation.

How much % is sparingly? I’m thinking of turning them off the entire print. It’s a pretty large print

Try with maybe 20-30% speeds after its printed several layers at 0%. You might even try your idea of zero fan the entire time. It’ll take trial and error so you may figure out a way to test on a smaller print so you don’t waste a bunch of filament.
