While science teachers everywhere are already calling for the inclusion of 3D printing courses in high schools, a new Korean innovation suggests it can even be taught in junior high. For plastics manufacturer BnK (Books and Kimchi) have just announced a new line of PLA filament that has anti-microbial properties. They believe this filament, called Purement, is the first of its kind and is perfect for use in homes with children and in schools.
While you could argue about the point of introducing kids as young as eight or ten years old about 3D printing, the concept behind this filament is very clever. Anti-microbial substances kill or inhibit the growth of a vast number of bacteria, and Purement itself has been extensively tested for these properties. ‘According to company studies, Purement has been proven to eliminate 99% of staphylococcus aureus and colon bacillus bacteria in laboratory tests and also prevents them from spreading, thus helping to reduce the risk of infections,’ BnK reveals. This company, for the record, specialized in manufacturing plastic components for the automobile industry but have recently moved into filament production as well.
Their anti-microbial properties are further certified by a Korean patent, while a US and international patent is pending. As BnK revealed, their properties were even certified by KOLAS and are compliant with RoHS (Restriction of Hazardous Substances) regulations, which have been developed by the EU. ‘This means that it doesn't contain lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers. These restricted materials are hazardous to the environment and pollute landfills, and are dangerous in terms of occupational exposure during manufacturing and recycling,’ BnK reveals. Purement’s harmless properties are also backed by the SIAA (Society of Industrial technology for Antimicrobial Articles) and SGS (Société Générale de Surveillance).
