This faux x-ray was created for a Scuba Diving Magazine story about a sea turtle that had been maimed by a boat’s propeller. BTech Innovations, a Turkish company specializing in custom-designed prostheses and implants, got involved. They performed a series of detailed CT scans to create a 3D model of the turtle’s skull and damaged jaw. They then designed a bespoke prosthesis and 3D printed it with a medical-grade titanium alloy that is lightweight yet durable enough for a lifetime in the ocean.
