How To 3D Print A Prosthetic Hand

Prosthetic limbs have come a long way in recent years, thanks in part to the advancements in 3D printing technology. 3D printing allows for the creation of custom prosthetic devices at a fraction of the cost of traditional methods, making them more accessible to those who need them. In this article, we’ll take a closer look at how to 3D print a prosthetic hand.

Get a 3D Model of the Prosthetic Hand

The first step in 3D printing a prosthetic hand is to get a 3D model of the hand. You can find pre-designed 3D models online that are free to download or purchase. There are also organizations that provide open-source 3D printable prosthetic hand designs that can be modified to fit individual needs. Alternatively, you can design your own prosthetic hand using CAD (computer-aided design) software.

Prepare the 3D Model for Printing

Once you have the 3D model of the prosthetic hand, you will need to prepare it for 3D printing. This involves optimizing the file for 3D printing and ensuring that it is the right size and shape. You will also need to add supports to the model to ensure that it can be printed without collapsing.

Choose the Right 3D Printing Technology and Materials

There are several 3D printing technologies and materials available, but not all are suitable for 3D printing prosthetic hands. Fused Deposition Modeling (FDM) is one of the most common 3D printing technologies used for prosthetics due to its affordability and accessibility. As for materials, you can use PLA, ABS, or PETG filaments for the 3D printing process. They are lightweight, durable, and easy to print with.

3D Print the Prosthetic Hand

With the 3D model optimized and the right materials and technology chosen, you can now 3D print the prosthetic hand. The time it takes to print will depend on the size of the prosthetic hand and the resolution of the 3D printer. Once the 3D printing process is complete, you will need to remove the supports and clean up the model to ensure a smooth finish.

Assembly and Final Touches

After printing and cleaning up the model, you will need to assemble the prosthetic hand. This involves attaching the joints, tendons, and other mechanical parts. You can also add final touches such as a grip or textured surface to improve the user’s grip on objects.


3D printing a prosthetic hand is a complex process that requires technical knowledge and skill. However, with the right equipment, software, and materials, it is possible to create a custom prosthetic hand at a fraction of the cost of traditional methods. By following these steps, you can create a prosthetic hand that is tailored to the individual’s needs and can significantly improve their quality of life.
