3D-Printed, Useful Metallic Glass Structures
Mar-23-18
A new method of 3D-printing metallic glass materials could lead to stronger, lighter and more resilient structures.

Developed by a team at North Carolina State University, the ‘amorphous metal alloy’ structures overcome the typical limitations of the material, which must be cast quite thin in order to prevent crystalline structures from forming. To create thicker, more useful objects, the team used 3D printing to apply metal powder in layers, melting the powder and then applying more layers a bit at a time. The result was a solid, metallic glass object, proving the technique could be used to create “a variety of complex geometries” for a range of applications.
