Feature Bone fractures fixed by 3D bio-printed silk from spiders and moths Seoul South Korea’s Rural Development Administra- tion and Hallym University have collaborated to create a 3D Silk-Printing System that produces components suitable for use within a liv- ing organism. The new silk ‘f ilament’ is made from fibroin protein that also con- stitutes 75% of the silk naturally produced by spi- Silk cocoons in Dalat, Vietnam. ders and moth larvae. The fibroin will be used to recreate the plates and screws used to fix broken bones. One problem this overcomes is that trad- itional metal implants, at some point, may have to be removed from the body. While there are other plastic polymer substi- tutes trying to solve the same issues, the ‘silk ink’ in this research could be a stronger, more durable and a lower-cost option.
