ASA and ABS are warp prone and this is an 11" / ~275mm wide print that’s equally tall 🤷

The build volume of my printer means lots of surface area for the acrylic enclosure, which in turn makes it hard for me to exceed a 50°C chamber temp, despite 4x bed fans.

The next print, with normal supports, pulled the bed off the magnetic build plate. Insulation eliminated warping and let me pull off the print.

I do agree that a “nicer” enclosure is the preferred method. I have zero issues with PETG at this size. I’ve never tried PLA on this printer, but it should be fine too.
