Has anyone else run into this? About half the time when I purchase a 3D printed car, the resin is rubbery, and will distort just by handling. I tried carefully exposing them to sunlight, but to no avail. These same bodies will distort at surprisingly low temperatures as well (95 degrees, F). Printers have made great strides, perhaps it's time to look at resin formulations? I'd love to hear any other experiences.
