Copper3D is a Chilean company born by the union of engineers, physiotherapists and doctors to solve the skin problems suffered by patients using prostheses. More than 40% of amputees and also many other patients who use prostheses, suffer some dermal disorder due to the high bacterial load that these medical products present in contact with the skin, which lead to dermatitis, folliculitis, fungal infections and more. This problem is due to the fact that the materials used in medical devices are difficult to keep clean and sterilized. To cover this cadence, Copper3D has developed a new polymer for 3D printing with an additive containing copper nanoparticles, highly effective to eliminate fungi, viruses and bacteria, but safe for humans at the correct concentrations.
PLACTIVE AN is a new nanocomposite consisting of high quality PLA and a copper nanoparticle additive (1-2%) with the advanced properties shown below:
To show the world the power of PLACTIVE AN1, Copper3D has sent samples of its product to two microbiology laboratories. Both institutions confirm that the Colony Formation Units (CFU) of Staphylococcus aureus MRSA and Escherichiacoli DH5 α, drop drastically during the first 6 hours of exposure to the PLACTIVE (> 95%), also eliminating bacterial strains up to 98% in the 8 first hours and 99.99% after 24 hours. The antibacterial power of PLACTIVE AN1 is clearly shown in the following graph.
The advanced antibacterial properties of PLACTIVE AN1 is ideal for the entire medical ecosystem: patients, hospitals, doctors, universities; and easy to print for all types of users of a 3D FDM printer. As an example of a sanitary application, the manufacturer Copper3D has published the design of a mask for 3D FDM printing.
