10 Thinks to Know About Casting Copper Alloys: Versatile and cost effective, copper alloys open up many design choices for engineers.
Advancing 3D Printing for Metalcasting: While 3D sand printing has seen a drastic increase in use over the last five years, the technology is primarily used for small- to medium-scale prototypes and high-mix, low-volume tooling. As new technologies are developed, the speed and scale of printing is believed to increase exponentially. Two recent studies on 3D printing for metalcasting are shared.
