In the early days of additive manufacturing (AM), the technology was primarily focused on design and rapid prototyping applications. However, recent additive manufacturing is progressively being employed to create high-performance mechanical components from refractory and technical materials.This is particularly common in space and aerospace engineering, where the combination of affordability, versatility, speed, and precision make additive manufacturing a desirable choice.Its ability to print refractories in lightweight architectures makes it an appealing method, supplying high-temperature performance at a tiny proportion of the weight of traditionally fabricated refractory metal parts.This article outlines the key strengths of AM compared to conventional subtractive manufacturing, and ho...

For nearly 100 years, scientists thought they understood everything there was to know about how metals bend. They were wrong.Materials science and engineering researchers at the University of Wisconsin (UW)-Madison have now demonstrated that the rules of metal-bending aren't so hard and fast after all. Their surprising discovery not only upends previous notions about how metals deform, but could help guide the creation of stronger, more durable materials.'This creates new opportunities for materials design,' says Izabela Szlufarska, a professor of materials science and engineering at UW-M...

Dr Daniel Penello, of Alexander Orthopaedic Associates, St. Petersburg, Florida, USA, has successfully implanted what is said to be the US’s first metal additively manufactured finger bone implant. The implant was designed for patient Robert Smith, whose middle distal phalanx was shattered in an ironworking accident in 2017.Smith was initially presented with the choice to live with the injury – which reportedly left him with no function and little feeling in the affected finger – or to opt for amputation of the digit. However, following further research and with the assistance of Additive Orth...

July 2019 marked the 50-year anniversary of the Apollo 11 moon landing. While the world has seen incredible technological and scientific strides since then, the broader space industry has been in stealth mode—exploring what’s possible, and what’s next, for humankind in space.In 2018, the space sector grew to an incredible $3.25 billion industry. A number of different technologies are driving this rapid growth, but the most promising one is industrial-grade 3D metal printing (a.k.a. metal additive manufacturing). Once met with skepticism, 3D metal printing has proven it...

Typical MIM parts used in disposable surgical instruments and assembled in a clean room. (Image from Micro)Metal injection molding (MIM) works well for high-volume production of small, complex medical device parts of consistent quality.Demand for small, lightweight, high-strength, complex-shaped components is growing across industries today, from automotive, consumer electronics, aerospace and defense to orthodontics and medical devices.Traditional machining and injection molding each has its pros and cons in producing components for medical devices, especially where parts may be smaller and r...
