Silk isn’t just used to make gorgeous, expensive clothing—this biocompatible, natural protein fiber is much stronger than it looks.

 .

The protein is made of 75% biocompatible fibroin, and 3D printed silk has many applications in the medical sector. The Abbott Lab at Carnegie Mellon University ( CMU ), run by biomedical engineering professor Rosalyn Abbott, works with regenerative medicine and materials science, investigating how tissue development and disease are affected by the 3D microenvironment and studying topics like adipose tissue engineering strategies and non-invasive tissue assessments…and silk biomaterials.

Silk worm CMU undergraduate student Tahlia Altgold said, “Silk is a really incredible biomedical material that’s been used for a long time in things like sutures.” Altgold is a junior at the university, majoring in both materials science and biomedical engineering , and is a researcher in the Abbott Lab working to develop a new 3D printing technique for […]
