Our take on metals additive manufacturing (AM) is that it has made it past the “valley of death” in the so-called hype curve. It is being used widely and sometimes for unexpected applications. For example, I was impressed to hear a presentation from the Sonova Group about printing custom hearing-aid earpieces in titanium, for which the unexpected benefit was much better robustness against being dropped on the floor and crushed underfoot.

The disruption of supply chains caused by the COVID-19 pandemic is leading U.S. companies to rethink their manufacturing operations. We relearned an old lesson – agility is vital.

Ceramic oxides and carbides find widespread use in technologies ranging from solar cells and electronics to high-durability, impact-resistant surfaces for military and aerospace applications.

A relatively recent phenomenon in the field of additive manufacturing (AM) has been the discovery of “keyholes” (i.e., flaws) that form during the metal AM process. AM’s promise to revolutionize industry is currently constrained by a widespread problem: tiny gas pockets in the final product, which can lead to cracks and other failures.

Much of the current research and development in additive manufacturing is devoted to making parts from just a few specific alloy compositions.

Despite its history and ubiquitous presence as an infrastructure material, steels remain a complex material system with many persisting research questions.

Additive manufacturing (AM) is changing how we think about making parts from metal.

The human brain is rather good at recognizing a large variety of objects: a chair, a ball, a hang-glider, etc. Recognition is usually almost instantaneous, assuming one learned at some point in the past what each of these objects is called.

Every day we use dozens of electromagnetic devices, from a simple water heater to brew a cup of coffee to cell phones, office computers, light bulbs, elevators, air conditioners and so on. What all of these devices have in common is that they use either electricity or magnetism or, in many cases, both.
