Antiviral 3D Printing Materials

I&T Wish Antiviral 3D Printing Materials
(REF: W-0443)
Matched I&T Solution
Trial Project
Summary and Challenges

Pathogens on high-touch surfaces can transmit diseases which could threaten public health. Different types of solutions could be found on the market such as sterilization coating on existing material to address the issue. A research found that adding antiviral compounds in existing material can pierce the cell membrane of bacteria and viruses and kill it. Comparing with sterilization coating, the material with antiviral compounds is expected to be more durable and have prolonged sterilization effect. Even if the surface of the material is abraded, the sterilizing agent in the inner layer can still perform.

This project aims to customize the material with antiviral compound through 3D printing technology, which could be applied to frequently touched surfaces, and test whether the compound can prevent transmission through contact effectively. 

Expected Outcome Through 3D printing technology, customized covers with sterilization capabilities could be applied on existing high-touch surfaces during the trial. Potential trial sites may include door handles, lift buttons and toilet caps. Periodic sampling on the installed material and testing in qualified laboratory will be done to prove the effectiveness.
Expected Trial Duration 3-month
