Perm scientists proposed 3D printing and carbon fibers for creating prosthetics.


Specialists from the Perm National Research University have developed a promising method for creating comfortable and durable exoprostheses through 3D printing using polymers and carbon fibers. Here are the key points:

  1. Personalized Exoprostheses: The researchers have developed a method for creating exoprostheses (external prosthetic limbs) tailored to the individual’s body structure. This personalization is achieved through 3D printing.

  2. Improved Mechanical Properties: The 3D-printed exoprostheses are reinforced with continuous carbon fibers, enhancing their mechanical properties and durability.

  3. Orthopedic Socket: These personalized exoprostheses are designed to connect to the body using a specialized orthopedic socket. This socket is precisely designed to match the remaining limb’s and soft tissues’ geometry.

  4. Research and Variations: 16 different versions of these prostheses were created during the research. These variations allowed scientists to study the physical interaction of the prostheses with muscle tissue. Other polymers and placements of carbon fibers were experimented with.

  5. Importance of Carbon Fibers: The study highlighted the significance of reinforcing low-elasticity polymers with carbon fibers, particularly in how forces are distributed within the exoprosthesis socket. The distribution of fibers throughout the prosthesis was crucial for achieving the best strength.

This research holds promise for developing more comfortable and durable exoprostheses that can significantly benefit patients who have lost limbs. The use of 3D printing and carbon fibers allows for personalized solutions that consider each individual’s unique anatomy.
