The Bad Dragon sex toys I've handled aren't 3d printed. (You wouldn't expect them to be, since 3d printer output is rigid plastic, which you don't want a sex toy to be, and covered with fine ridges, which you really don't want a sex toy to be.)

It's possible that the molds are 3d printed, but if they are, it's using a printer with amazing surface finish, and Bad Dragon's never said anything about using 3d printing. Much more likely they're using conventional manufacturing processes.
