3D-printed casts for fractured bones could replace the usual bulky, itchy and smelly plaster or fibreglass ones in this conceptual project by Victoria University of Wellington graduate Jake Evill.
The prototype Cortex cast is lightweight, ventilated, washable and thin enough to fit under a shirt sleeve.
A patient would have the bones x-rayed and the outside of the limb 3D-scanned. Computer software would then determine the optimum bespoke shape, with denser support focussed around the fracture itself.
The polyamide pieces would be printed on-site and clip into place with fastenings that can’t be undone until the healing process is complete, when they would be taken off with tools at the hospital as normal. Unlike current casts, the materials could then be recycled.
