One of the main challenges with materials in this pandemic is hygiene. You can imagine that materials that have antibacterial properties are high in demand these days. Just one week ago, Spanish company Recreus launched a new 3D printing filament, PP3D. This material turned out to be an ideal solution against COVID-19, thanks to its chemical resistance, smooth finishes, low warping or deformation, and no toxic properties. But there are also other materials that could be used specifically for their antimicrobial properties. Here they are:

Healthfil is a range of 3D printing filaments, developed Italian company Treed Filaments. The filaments are developed specifically for orthopedic uses, such as 3D printed busts, upper and lower limb prosthetics, and are therefore certified for skin contact. The company does not claim that the materials are antibacterial, but because of the properties of the materials, they can be sterilized in an autoclave at 125° C.

SPEE3D’s 3D printed ACTIVAT3D copper is another example of a material that can help fight the spread of COVID-19. The anti-microbial copper is 3D printed in a fast and affordable way onto existing metal surfaces. According to the website 96% of SARS-CoV-2, the virus that causes COVID-19, are killed in just two hours.

The antibacterial PLA from XYZPrinting is a special filament using silver ions which is said to inhibit bacterial growth by at least 99 percent, greatly reducing the risk of infections. The material is perfect for 3D printed products used in households and schools.

Copper3D is one of the companies that focuses on antibacterial filaments for 3D printing. The material is ideal for the manufacture of medical applications where it’s dangerous to have bacterial contamination, such as 3D printed postoperative prostheses, wound dressing and 3D printed surgical equipment (also up top).
