For the uninitiated: 3D-printed sex toys actually do exist, yes. For example I believe the infamous Dragon Dildos are 3D-printed? (I shan't link, for self-explanatory reasons.)
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.
I don't think this is that kind of site! ;) Seriously, you can find Bad Dragon with a Google search if you're curious, provided safe search is off naturally, and don't expect autocomplete! They're very exotic designs, often quite large (we have one as a present from a friend, largely as a conversation starter... or stopper!) and the kind of niche low-volume manufacturing in complex shapes that 3D printing can work out well for.
