The Challenge of Reclaiming Carbon Fiber for 3D Printing

By: Brent Donaldson, Senior Editor

Carbon fiber composite materials weigh significantly less than steel while offering comparable strength and performance. But recovering and recycling continuous fiber for additive manufacturing applications — without any effect on the mechanical properties — has proven extremely difficult. Here is how Oak Ridge National Laboratory is working to solve the challenge.
