TriFusion Devices

TriFusion Devices, founded in 2016 by Dr. Blake Teipel and Charles Brandon Sweeney, emerged from the materials science and engineering department at Texas A&M University. Teipel, with a Ph.D. in the field and experience at NASA and John Deere, and Sweeney, a graduate student at the time, leveraged their academic research to address a significant gap in the medical device market. The company was established to revolutionize the production of custom prosthetic and orthotic devices, a market often characterized by high costs and long manufacturing times.

The core of TriFusion's business is a proprietary additive manufacturing process. This technology utilizes a specialized 3D printer with an integrated microwave unit that welds layers of a carbon nanotube-coated filament together. This microwave welding technique creates parts with strength comparable to traditional injection-molded or machined components, overcoming a common weakness in layer-by-layer 3D printing. The primary clients are prosthetists and amputees who benefit from a drastically reduced timeline for receiving custom-fit devices. Instead of the typical six to eight-week fabrication period, TriFusion's technology can deliver a finished product in as little as 48 hours.

The business model centers on providing both 3D printing services and the specialized materials required for their process. This approach significantly lowers the cost and labor involved in producing items like prosthetic sockets. A key benefit of their material technology is the ability to make post-printing adjustments to the fit without extending the production time. The company's journey was marked by numerous wins in business plan competitions, including the Rice Business Plan Competition, which provided significant seed funding and visibility. In October 2016, shortly after its founding, TriFusion Devices was acquired by Essentium, another company co-founded by Blake Teipel, which focuses on industrial-scale additive manufacturing.
