Personalization: Prostheses can be manufactured to the exact shape and size of a patient’s residual limb, resulting in enhanced comfort and function.
Affordability: The price of 3D-printed prostheses is much cheaper than conventional options and is therefore marketable to patients living in low-income settlements.
Faster Production: It takes several days instead of weeks or months to print a prosthetic.
Adaptability for Children: A growing child can easily grow out of a physical prosthesis, but 3D printing supports fast and cheap substitute parts.
Case Study: Prosthetics for Developing Nations
However, organizations such as e-NABLE and Open Bionics are using 3D printing to offer low-cost prostheses to children and adults who live in neglected communities. For example, a 3D-printed prosthetic hand costs as little as $50, while conventional models are significantly more expensive (thousands).
Implants and Surgical Tools: Precision and Customization
3D printing has also made significant strides in the production of implants and surgical tools, offering solutions tailored to individual patients.
Custom Implants
Three-dimensional (3D) printing allows the generation of patient-unique implants for bones, joints, and dentition applications. This precision reduces complications and improves outcomes.
Orthopedic Implants: Customized hip and knee replacements are created to fit perfectly, reducing the risk of implant failure.
Dental Implants: 3D-printed crowns and bridges are fabricated with such accuracy to match a patient’s teeth to a very high degree.
Cranial Implants: Three-dimensional (3D)-printed cranial plates are an anatomic fit for patients having head injury or deformity.
Surgical Tools
Surgeons can employ 3D printing for custom-made surgical instruments, e.g., for guidance of intricate procedures. These tools ensure greater accuracy and reduce surgery time.
