What are the benefits of 3D printing for the sex toy industry?

3D printing brings many advantages to the 3D printing industry. Here are the main benefits of 3D printed sex toys:

  • Personalization: 3D printing offers unique personalization capacities, which is a powerful advantage for sex toys.
  • Homemade: Sex toys 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 toys online. Users can then download or stream the STL file to 3D print it at home using a desktop 3D printer. It is also possible to design and purchase a 3D printed dildo online. The manufacturer 3D prints the object and then ships it to the customer. Companies that offer this type of service can often produce 3D models and prints from penis pictures. Those intimate objects can be compatible with standard vibrators. A full infographic on the benefits of 3D printing for the sex toy industry is available on here.

Creating 3D printed sex toys at home

Downloading and 3D printing sex toy designs

Many online platforms offer a wide choice of 3D designs for adult toys. Cults3D, for instance, offers dozens of different sex toy designs, downloadable for free or at a low price. There is a large choice of shapes, colors, and sizes available.

Eccentric 3D designs (like celebrity busts) can also 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. Upwards 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 the SexShop3d website, accessible only to a mature audience.

They recently introduced one of their latest creations, the Viper silicon dildo mold, on their website. This one-of-a-kind sex toy is available for $5 and the size of the printable mold can be resized according to one’s needs. The molds can be 3D printed even without support structures. Dragon Skin® High Performance Silicone Rubber material, a food-grade silicon, is recommended by most companies.

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 right, by SexShop3D, explains very clearly how to make a 3D printed sex toy safe for use. To prepare your 3D printed sex toy you need to:

  • Make sure the material is non-toxic and safe for intimate interactions. Polished ABS coated with silicon is a very good option, as demonstrated in the video.
  • Make sure the surface is smooth and nonporous: remember to polish carefully your 3D printed sex toy after 3D printing it using sandpaper to make the surface the smoother possible. Then you can spray the 3D printed dildo with a silicone conformal coating spray. Make sure the silicon coating spray you use to cover your 3D printed sex toy is food-safe. And of course, don’t forget to wash your 3D printed sex toy before and after every use :).

Services for 3D printing customized sex toys

Designing your own sex toy online

Online 3D software allows customers to create their own custom sex toys in 3D, such as dildo-generator.com. 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. 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.

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 sex toys’ 3D file directly to their 3D printer. The platform even allows 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.

You just need to get the free software OpenSCAD to open the Dildo Generator .scad script. This generator of sex toys for 3D printing allows you to change parameters such as the dildo length and diameter, before easily generating the STL file of the sex toy ready to be 3D printed!

Accessories for 3D printed sex toys

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.

SexTech startups and 3D printed sex toys

Failed 3D printed sex toys startups

As explained in this ModelViewCulture article, sex tech startups live in a hostile business world. Those focusing on 3D printed sex toys are no exceptions.


One of the best examples of what could go wrong is what happened to intiimi, a startup whose mission was to develop a new kind of “Sexual Wellness Devices” intended to disrupt the 12-billion-dollars-per-year sex toy industry. Intiimi wanted to offer a mass customizable cloud-enabled robotized sex toys, offering the ability to measure and respond to one’s body states of arousal in real time.

Even if it was very promising, the project failed after a few months. For more information, read intiimi’s founder Bartosz Bos post about “How to kill your 3D printed startup in 3 easy steps”.


Another 3D printing startup on the sex toys segment that failed to deliver was FrenchCoqs.fr (cool name huh?). They went bankrupt within one year of their launch. The option to create a personalized 3D printed dildo shaped from real life pictures was what you might call a killer app, but this did not bring in enough clients.
