Researchers Developing 3D-Printed, Anti-Bacterial Silver Lining for Implants to Resist Infection

(Engineer)  Researchers at Birmingham University are developing implant designs and 3D printing techniques to produce surfaces that are resistant to bacterial contamination. Most prosthetics carry a low risk of infection of below one per cent. But where implants are inserted following an accident, or must be produced at the hospital, the risk of infection can increase significantly, to up to 50 per cent.
The team will combine technology to embed silver into the material used to build implants, with additive layer manufacturing to produce the prosthetics, according to Birmingham’s Prof. Liam Grover. Using selective laser melting, they will use lasers to fuse powders together layer by layer, creating a porous structure to which the bacterial-resistant silver can be added.
