Thanks to digital technologies, prosthetic and orthotic devices can be quickly designed, adapted to the body shape of a specific user, and then printed precisely according to the requirements for movement support, stabilization and rehabilitation.
Benefits of 3D printing for prosthetics and orthotics
- Individual customization:
Each patient has unique body proportions and specific needs. 3D printing allows for detailed scanning of the affected area of the body and the creation of a device that perfectly adapts to the given shape. This increases comfort, reduces friction and pressure points, and allows for precise support and control of movement.
- Faster and more affordable manufacturing:
3D printing reduces production time because the design and production are carried out directly from the digital model without the need for lengthy manual adjustments. This allows production to take place in local laboratories, which reduces costs and speeds up the availability of the device.
- Lightness and strength of materials:
Modern printing materials combine low weight with high strength, which is essential for the comfort and mobility of users. This is especially important in prosthetics, where lower weight and proper load distribution ensure better movement properties and long-term comfort.
- Aesthetic options and personalization:
3D printing allows for customization of design and colors so that patients can express their style or integrate the device more into their appearance. Aesthetics are of great importance in prosthetic devices, as they help increase self-confidence and improve the psychosocial well-being of users.
- Integration with smart technologies:
In the case of 3D printed prosthetics, devices can be easily integrated with electronic sensors and smart technologies, such as bionic prostheses with motion sensors, which increases their functionality. These prosthetic devices can learn from the user’s movement habits and adapt to them.
Examples of 3D printing in prosthetics and orthotics
- Limb prostheses:
Thanks to 3D printing, prostheses can be easily created that exactly match the shape of the stump and the user’s specific movement needs. This is a major benefit, especially for children who grow rapidly and need to replace their prostheses frequently. 3D printing allows for the rapid production of new prostheses at a lower cost, which is key to long-term comfort and adaptation to growth.
- Motion support orthoses:
Orthose for different parts of the body, such as the back, wrist or knee, can be manufactured to match the individual proportions and needs of the patient. 3D printing ensures strength, lightness and precise force distribution, which contributes to better support, stabilization and rehabilitation.
- Bionic limbs:
Modern 3D printing enables the production of bionic prostheses, which contain sensors and movement mechanisms that respond to impulses from the nervous system. These prostheses can mimic the natural movements of fingers or limbs, thereby improving functionality and allowing for smoother and more natural movement control.
- Orthoses for children:
For children with movement disorders or the need for orthotic devices, such as scoliosis or other movement problems, 3D printing offers the possibility of quickly and cost-effectively producing devices that can be adapted to the child's growing body.
