Researchers at the University of Bath have integrated advanced three-dimensional scanning to generate digital models for affordable and more personalized lower-limb prosthetic liners.

The technique first accurately scans an amputee's residuum then feeds the data into a digital model, which is used to design the liner. The liner is then fabricated via cryogenic machining, eliminating the need for complex, time-consuming molds. The liner is made from a soft-polymer neoprene-like material, offering greater comfort to amputees compared to conventional silicon liners.

The complete process, from scanning to fitting, takes less than 24 hours.
