I literally bought a few pounds of used stuff. It is the most reliable and gentle printing material on the market. Having seen many of my ABS prints warp and fail, PETG is strong enough for drone parts, battery boxes, and other large structures. For small prints, PETG has a predictable (minimum) shrinkage factor. I ran this footage through an AirWolf HDR 3D printer at 240-260 with no problems.
