Why 3D Printed Sex Toys Are Not Safe to Use
It seems like a great idea to use a 3D printer in order to print out a sex toy. After all, you can do it in the privacy of your own home without anyone knowing what you are making and it is an instant sex toy. So what could go wrong? A lot.
The way a 3D printer works is by creating an object made of thin layers of a material based on a pre-configured blueprint or template. The material that is used is based on the 3D printer filament or cartridge that you select in order to create an object. 3D printers use a variety of materials to create objects such as ABS plastic, nylon (PLA, polyamide), epoxy resins (stereolithography materials), glass filled polyamide, metals and more. However, most people use ABS plastic, especially when printing out a 3D sex toys.
When an object is created by a 3D printer each printed layer builds on the other in order to create the form that you desire. It can look solid but it actually is not which leads us to the first reason why using a 3D printed sex toy is not safe to use. The microscopic gaps in the 3D printed sex toy are perfect for storing bacteria, fungus and mold as well as transferring sexually transmitted infections and diseases (STDs / STIs). Specific examples include bacterial vaginosis (yeast infections), cystitis (a.k.a. painful bladder syndrome / PBS) urinary tract infections (UTI), and STI's which are transferred from one sexual partner to another by sharing a 3D sex toy such as chlamydia, syphilis and herpes.

Is Using a 3D Printed Sex Toy with a Condom Safe?
The surface of a 3D printed sex toy is quite rough and is not great for making anything that comes into contact with the body such as footwear, bracelets, mouthguards, etc. as they have tiny splinters that can cut into and embed into the skin. While you can use a sander or chemical bath to smooth out many of the rough spots, the tiny splinters remain, but are just smaller. This can still cause skin irritation and in some cases infections especially when used internally as are most 3D sex toys.
Some may logically conclude that if they simply put a condom over the toy they are safe from the bacterial issues and should be good to go. However, this illusion of safety is not one that should be depended upon because the layers of the 3D sex toy can break and splinter causing small punctures through a condom, thus, making even that layer of protection useless and putting the user at risk for damage to their body.
Is Using a 3D Printed Sex Toy with Silicone Conformal Coating Safe?
It has been suggested by some that you may be able to spray on a silicone conformal coating (often used to waterproof circuit boards), however, the layers are so thin that it will take a great deal of coats and even then you may not have made the 3D sex toy safe because silicone conformal coating can cause defatting and drying of skin which may result in skin irritation.
The Only Way to Make a Safe 3D Printed Sex Toy
There is only one way at this time that one should use a 3D printer to make a sex toy and that is to print a hollow cast imprint of a sex toy and then pour a safe substance such as silicone or rubber into the mold in order to create a solid, safe sex toy. The issue here is that casting a rubber, platinum-cure silicone or a tin-cure silicone mold requires a great deal of effort, money and equipment.

Are 3D Sex Toys Worth Making?
Unless you are going to manufacturer sex toys by casting sex toy molds and invest in the equipment needed to do it then the answer is that they are not worth making as they are not cost effective to make a mold for a single sex toy and when simply 3D printed, they are not safe to use. Our advice is to only use nontoxic sex toys that are manufactured by reputable sex toy manufacturers and enjoy discreet shipping from a reputable sex toy retailer.
