A new 3D-printing approach using metallic glass could open the door to 3D-printed metallic objects.
Despite the rapid advances in 3D printing, metal remains notoriously difficult to print with. To widen the possibilities of 3D printed objects, a team from Yale University turned to bulk metallic glasses (BMGs), a metal material that can soften for printing while remaining tough, elastic and resistant to corrosion.
Using a common BMG made up of zirconium, titanium, copper, nickel and beryllium heated to an extrusion temperature of 860° F, the team was able to print a metallic structure in the ambient conditions similar to conventional thermoplastic 3D printing.
