Johnson Matthey 3D prints with precious metals to produce anti-bacterial prosthesis

  • While most 3D printed prosthesis carry little risks of infection, implants—by their nature—pose a greater risk. Addressing this, the researchers are developing specific 3D printing techniques and surface materials to reduce the possibility of infection.
  • As part of the consortium, Johnson Matthey is investigating 3D printing precious metals, currently embedding silver into the 3D printing process. Producing cranial implants in hospitals often involves use of a titanium sheet molded around a 3D printed implant. This is then sterilised to reduce the risk of infection but the research team believe this can be further eradicated with the use of anti-bacterial silver.

A shell upgrade for Seemore the sea turtle

  • Seemore, a sea turtle with an injured shell, is set to receive a more permanent solution for her ailment from a team of University of Minnesota students.
  • The team had to learn sea turtle anatomy to render a 3D digital model of the shell. The CT scan will allow them to make their model, which will aid in coordinating the design of Seemore’s prosthesis.
