What Would You 3D Print with Purement, a PLA that Kills Germs?

BnK has just informed us they have a new filament ready for market. According to BnK, their new filament is a PLA-based antibiotic/anti-microbial filament and has the ability to kill germs that it comes in contact with, which makes one wonder at the possible uses of such a filament.

The aptly named BnK (Books and Kimchi) Chemical Corporation was founded in 2009 to provide polymer components for the Korean automotive and construction industries, but has moved into the 3D printing realm to become one of the very first domestic FDM filament manufacturers in South Korea. Back during our first meeting, Kim Young Soo, Management Team Leader for the company, told us that he could see that there are several applications that 3D printing could be put to, but that new types of feedstocks were needed. He said that it was his company’s intent to explore and develop new ones, and that to this end, they had opened a new research and development center.

Well, it seems that they have put that research center to good use, as they have just informed us they have a new filament ready for market. According to BnK, their new filament is a PLA-based antibiotic/anti-microbial filament and has the ability to kill germs that it comes in contact with, which makes one wonder at the possible uses of such a filament!

The company is calling it “Purement” as in “pure filament” and told us that it is now protected by a Korean patent, and has US and International patents pending. According to BnK, Purement uses inorganic antibacterial ingredients, as these ingredients are more durable (up to 2 years, they said) than organic compounds. They also told us that the active ingredients they used have been approved by the FDA and SIAA (Society of International sustaining growth for Antimicrobial Articles) for antibacterial purposes, and the filament’s antimicrobial effect was certified by KOLASand eliminated 99% of the germs tested (colon bacillus and staphylococcus aureus). They also said that it was tested by SGS in accordance to US FDA 21 CFR 177.1520 and had passed. … (read more)
