3D-printed parts have killed dangerous bacteria, leading to the possibility of printed items that protect the lives of vulnerable patients in hospitals and care homes.

 .

Objects built using the technique could stop the spread of infections such as MRSA , said researchers from the University of Sheffield. A team from the department of mechanical engineering and the school of clinical dentistry built the parts, which combined 3D printing with a silver-based antibacterial compound.

 .

Results showed the compound had no negative influence on material processing or part strength. Under the right conditions, the parts demonstrated anti-bacterial properties without being toxic to human cells. The findings could be useful in a wide range of areas including medical devices, frequently-touched hospital parts, door handles, children’s toys, dentures and consumer products such as mobile phone cases.
