Through the process of layering powder and a binding liquid, binder jet printing could lower the price of magnetic shape-memory alloys and open up new possibilities for magnetic actuators in manufacturing, robotics, medical devices engineering, and a
variety of other industries.
Magnetic Shape Memory powder used for Additive Manufacturing
“We are mainly focused on research that will establishes binder jet printing as a superior manufacturing technique for these functional materials. If this kind of AM is possible, more intricately-shaped actuators can be designed for things like robotic
hands, parts grippers, or foldable solar panels. They could complete more complex actuation sequences and be molded to perfectly grasp their target objects,” says Dr. Chmielus.
The study, “GOALI: From Powder to Functional Actuators: Binder Jet Printing of Magnetic Shape Memory Alloys,” is part of the NSF Grant Opportunities for Academic Liason with Industry (GOALI) program. The program encourages interaction between academic
research institutions and industry.
“At both Pitt and Aerotech, we will work on the evaluation and comparison between single crystal and binder jet-printed functional materials. I am working on the fundamental research aspect of this proposal—an understanding of how powder size and shape,
printing, magnetic alignment, and processing affects microstructure and functional properties. Steven is working on actuator designs that would utilize these magnetic shape-memory alloys in either single crystal form or printed form,” Dr. Chmielus
