3D printing start-up Copper3D, based in Chile and the US, worked towards using Nano-Copper additives, and adding antimicrobial properties to polymers like PLA and TPU to create antibacterial 3D printed objects. Now, their team of researchers have come up with “Viral Inactivation System for a Breast milk Shield to Prevent Mother-to-Child Transmission of HIV”, a 3D Printed Device that can effectively inactivate the HIV virus under the right conditions on certain objects. The Split-Sample Study on 20 Samples revealed reduction in transmission, close to 100%.
