About 3D BioFibR
Dry-Spinning Fiber Production
3D BioFibR Inc. is a Dalhousie University spin-off company which uses a proprietary “dry-spinning” process (mimicking spiders) to produce low denier multifilament fibers from proteins (e.g. collagen and spider silk). 3D BioFibR focuses on protein-based fibers, predominantly collagen, braided and woven to medical device OEMs and 3D in vitro tissue culture.
The key to our fiber process is the combination of high percentage protein solutions with a catalytic amount of scaffolding polymer which permits rapid, large scale production of fibers. This extensional flow applied during our dry-spinning process produces protein fibers with impressive mechanical properties. For example, our typical collagen fiber composed of 1,650 filament (300 nm diameter each) shows tensile strength of 250 MPa. This strength is 3X higher than native human tendons, which we hope to replace with our medical devices.
“600X and 60,000X more efficient than electrospinning and wet spinning respectively…”
Founded by Dr. John Frampton, Canada Research Chair in Biomaterials at Dalhousie University and Chief Scientific Officer at 3D BioFibR, the Company recently closed a seed financing round.
We will use funding from our first financing round to focus on the company’s proprietary resolution to the challenge of making high-quality biofibers at scale, which, until now, has limited the industrial applications of biocomposite materials. This approach is already 600X and 60,000X more efficient than electrospinning and wet spinning respectively, with continued focus on optimizing this process and adapting it to a pilot spin line capable of producing a few kilometers of target fibers in order to access key market opportunities.
