Hello All,
I’ve recently come upon a 3D printer and have been printing as a hobby. I was wondering how to print safe sex toys. I know that I can’t bust straight print a dildo or any other insertable and use it immediately. I don’t have too much experience in making things body safe.
I know Pla is safe to eat from but not necessarily safe for insertion. Not to mention the print lines might hurt especially if they layers are large. And sanding it won’t completely solve the issue. So maybe there’s a spray of some sort to coat the toy in a safer material.
The only other option I can think of is printing a mold and using a silicon/resin fill
Any tips and ideas would be awesome

Re: 3D Printing Toys
My approach for now is to design everything to be used with a condom -making the search for body safe materials less important. 3D printing generally produces surface impefections (pores etc) so insertables seem challenging.
The print needs to not stress the condom enough to damage it and stay in one piece if inserted/under stress. The latter is I think very important for body safe designs, calculating how the structure reacts to stress, designing with safe structural failure in mind etc.

Re: 3D Printing Toys
There's a few sex toy designs on thingiverse done this way.

Interesting, yea I can see why you would want to stress test before inserting. Would be a bad day indeed if a 3D print broke inside you. So maybe a good approach is to design one that’s structurally sound then find a way to cover the pores. I was thinking maybe instead of a condom maybe a silicon/resin dip to make a more permanent cover.

I’ve seen a few molds but I haven’t molded something before not sure what to use as a fill

Re: 3D Printing Toys
The common use for 3D printers would be:
- electrode holders
- chastity belts
- locks/handcuffs
Insertables are a difficult issue, as even if you use the printer just to create a mold, the texture won´t be smooth enough.

Re: 3D Printing Toys
If your printer can handle ABS, you can print and then acetone smooth the part. That would seal it and give a glossy finish.
There is also resin printers. Many of the resins are touch safe and once properly post-processed would be fine for your application. There are already adult toy companies that use resin printers for custom adult toys.
If I can find the time I will attempt a couple of test parts in ABS and then smooth them. I'll post pic here once that is done.

Re: 3D Printing Toys
As you are already clearly aware, be very careful with this.
Insertables, especially when used vigorously, hold another danger: Breaking apart, leaving very sharp edges, and a hard to retrieve piece of it inside you.

Yes, I most certainly CAN do it again!
Re: 3D Printing Toys
My gut reaction here is to assume that anything that comes out of a 3D printer is not body-safe both because of materials and (for unprocessed FDM prints) texture. You can solve the materials problem with body-safe silicone (think clone-a-willy kits, but there's likely suppliers of an equivalent product with a lot less markup). I imagine a coating process would work reasonably well for some types of toys, and that would also address the texture issue. For other types of toys, casting seems like a good bet, but I don't know what sort of interface to apply to your molds to prevent plastic fibers embedding themselves in the silicone. Maybe a condom works as a barrier here?
As others have noted - be extra cautious with things that are insertable, and anything that might break under load. It can be hard to predict the way that 3D printed parts fail - while a general guideline is "they're weak along the layer lines", different materials and infill patterns will have a big effect on other failure modes.
