3D Printing Multiple Metals in a Single Complex Structure: Guhaprasanna “Guha” Manogharan and his team at Penn State College of Engineering and the Center for Innovative Materials Processing through Direct Digital Deposition (CIMP-3D) have developed a method to 3D print complex parts with different materials to achieve multiple design and engineering goals.

Abstract

Manogharan: “Standard” single material LPBF is an established process that is very widely used by defense, biomedical, and automotive companies. Tech Briefs: What's the difference between using multiple materials and just making different alloys? In this way we can concurrently take advantage of the design complexity that LPBF offers with a single material but enhance the functionality by using multiple materials for new applications that people had not been able to think of because they could only print it with steel or only with copper.
