What are the added values for the sex toy industry?

3D printing offers unique personalization capacities, which is a powerful advantage for sex toys. Plus, they can be 3D printed in the comfort of your own home. However, homemade 3D printed sex toys require some preparation to be safe for use. 

A few specialized websites allow users to create custom sex toy online then download or stream the 3D file to print it at home using a desktop 3D printer. It is also possible to design and purchase online a 3D printed dildo which will be 3D printed by the merchant and shipped to the customer.

It is now possible to download 3D designs and 3D print them on a home 3D printer. There is a wide choice of 3D sex toy designs, in all types of sizes, shapes and colors.

Downloading and printing 3D sex toy designs

Many online platforms offer a wide choice of 3D designs for adult toys. MakerLove (now inactive) and Cults3D for instance offer dozens of different sex toy designs, downloadable for free or at a small price. There is a large choice of shapes, colors and sizes available. Eccentric 3D designs (like celebrity busts) can be found, along with penises of the most famous porn stars. Those files can then be 3D printed on personal 3D printers.

Before 3D printing a design, the most important things to check are the scale of the model and its orientation on the printing bed. Upward is most of the time the best option.

3D print a mold for casting a silicon dildo

With a 3D sex toy design, it is possible to either 3D print a sex toy or 3D print a mold for creating a dildo in silicon. 3D dildos can also be purchased on 3Dildo-toys website, accessible only to a mature audience.

The website Castomized offers hundreds of designs ready to be 3D printed and then molded in silicon. They recently introduced on 3DShare platform their latest creation, the Helisex silicon dildo mold. This one of a kind sex toy can be downloaded for less than 1$. The size of the printable molds are 70 mm x 70 mm x 60 mm (while the sex toy size is 60 mm x 60 mm x 100 mm). The molds can be 3D printed even without a support.

The interesting spiral shape of this sex toy makes it compatible for internal (ladies and gents!) and external (gents!) use. It is one of the few design that can be used as a 3D printed vagina. Castomized recommends the Dragon Skin® High Performance Silicone Rubber, a food grade silicon.

Getting a good finish on 3D printed sex toys

There are several recommendations for making the 3D printed sex toy compatible with intimate use. The video on the left, by SexShop3D, explains very clearly how to make a 3D printed sex toy safe for use. Another good ressource is this article on MakerLove (site now inactive but with good resources on the topic), very detailed and explaining how a 3D printed sex toy must be prepared.

Enthusiasts should make sure the material used in 3D printing is non-toxic and safe for intimate interactions. Polished ABS coated with silicon is a very good option, as demonstrated in the video. The 3D printed sex toy needs to be smooth and nonporous to be body safe.

Even without a 3D printer, there are many options to make a 3D printed dildo at home.

Designing your own sex toy online

Online 3D software allow customers to create their own custom sex toys in 3D, such as Such websites and services specializing in 3D printed sex toys are often easy to use and offer a preview of the object in the browser window. Once completed, the 3D design can either be 3D printed and delivered (in an unmarked package!) by the merchant, or downloaded by the customer in order to be 3D printed directly at home.

Paris-based SexShop3D is among the most advanced in this niche but fast growing sector. The company does not sell physical dildos or sex toys: they sell the 3D designs of these objects. Customers can easily customize, buy and securely stream the 3D file of the sex toys directly to their 3D printer. The platform even allow designers to sell their 3D sex toys creations, an approach similar to 3D printing giant Shapeways applied to sex toys. This unique approach could be the future of the sex toy industry, where digitally downloaded dildos could become an increasingly tempting alternative to the embarrassing trip to the local sex shop.

Bullet vibrators

It is easy to design 3D printed sex toys compatible with vibrators. Bullet vibrators are inexpensive and simple to integrate into plastic 3D printed sex toys. With a simple hole of 18 mm diameter and 60 mm in depth, the design will be compatible with most of the bullet vibrators available on the market.

The 3D printed sex toy will simply be turned into a vibe with different speed and power options. Some vibrators can be remotely controlled and offer multiple vibrating speeds.

For more information about this subject, a student started a DIY project and made an interesting mapping of the possibilities of vibrating 3D printed sex toys. Some technical details are discussed.
