    FDM printing is a bad idea for any material in a sex toy.

    There’s several issues:

    eventually, it’s going to delaminate. Worst case you catch it and it just causes some minor lacerations.

    Worst case? Shards of plastic stuck in your ass (or where ever,) while surgeons get intimately acquainted while playing a game of Operation. Only it ain’t a buzzer Making that noise.

    Secondly? Hygiene. FDM laminations create a bunch of ridged parallel to the print direction. These ridges (and cracks that form at them,) can harbor shit loads of bacteria and are best treated as single use (ie food safety.)

    ASA/ABS can be vapor smoothed with acetone but that causes other problems.

    Your safest approach is to use a “mold” setting in your slicer to print off two clamshell molds which you can then cast a silicone rubber version. If it needs some added stiffness…you can add printed parts inside and submerged in the cast.
