The GRCop story: The development, production and Additive Manufacturing of NASA’s rocket engine alloys

The new space race is powered by metal Additive Manufacturing. In turn, the Additive Manufacturing of rocket engines is powered by advanced alloys. Of these, NASA’s GRCop family has found use in numerous critical applications.

In this article, Austin Whitt and David Ellis, NASA Glenn Research Center, and Paul Gradl, NASA Marshall Space Flight Center, dig deep into the history, production, processing and maturation of these unique materials. As the authors reveal, there is good reason why Additive Manufacturing of GRCop begins by understanding the process-microstructure-property-performance relationship. Go to article

Additive Manufacturing in the jewellery industry: exploring the potential of platinum and titanium

Metal AM offers the jewellery industry significant creative and commercial opportunities. One such opportunity is the production of platinum and titanium jewellery by Laser Beam Powder Bed Fusion (PBF-LB), a process described as a “match made in heaven” for these metals.

This technology offers jewellery designers advantages that include greater creative freedom, the precise control of weight, and a path to scale-up production.

Here, Michela Ferraro explores the status of AM for jewellery manufacturers and highlights innovative and critically acclaimed pieces produced by the technology. Go to article…

Formnext 2023: Innovations in metal Additive Manufacturing from the industry’s leading international exhibition

When it comes to presenting a review of the world’s largest international exhibition for AM, one can go about it in two ways: very broad generalisations about the state of the industry or a more focused review of a handful of noteworthy developments.

Given the 859 exhibitors at Formnext 2023, spread over some 54,000 m2, this review by Dr Martin McMahon takes the latter approach, offering broader context where possible. Whilst many more press announcements are covered in the industry news section of this issue, the following report provides an overview of how – and where – AM is evolving and maturing into a credible and dynamic technology.
