Aluminium has emerged as a pivotal material in Additive Manufacturing, revolutionising industries such as aerospace, automotive, and beyond. Overcoming early processing challenges, advances in AM machines and alloy designs are unlocking aluminium’s potential. Today, its lightweight, high strength and thermal properties, combined with advances in powder production and sustainability efforts, are driving its rapid adoption. As Dr Martin McMahon explains, with growing applications and ongoing materials development, aluminium is poised to play a transformative role in shaping the future of AM technologies.

Hydraulic systems are important across many industries, providing high power density in compact, efficient packages. However, conventional subtractive manufacturing methods restrict design and performance. Additive Manufacturing offers a solution, enabling the production of complex geometries that enhance flow dynamics whilst minimising material use. In this article, Valeria Tirelli, CEO of Aidro Srl, considers how AM is reshaping hydraulic component design and production, offering new possibilities for enhanced performance, sustainability, and application-specific customisation.

With seven structural titanium parts flying on every Boeing 787 Dreamliner, a Master Supply Agreement with Airbus for the A350, and projects with the likes of Northrop Grumman and General Atomics, Norsk Titanium is setting the pace when it comes to the production of airframe components by Additive Manufacturing. By using wire instead of powder and its own proprietary version of the Directed Energy Deposition (DED) process, the company combines high deposition rates with aerospace-grade materials properties. Martin McMahon visited the company on behalf of Metal AM magazine.

There is a growing interest in additively manufactured pure tungsten, primarily propelled by the expected demand for tungsten components in future fusion power plants. Here, Additive Manufacturing veterans and PBF-EB enthusiasts, Ulf Ackelid and Ulric Ljungblad – both of Sweden’s Freemelt AB – provide insights into the AM of tungsten and the benefits of using an electron beam as the energy source. This article is a standalone continuation of previous PBF-EB articles in Metal AM, published in the Summer 2020, Autumn 2022, and Summer 2023 issues

In the race to improve the productivity of PBF-LB Additive Manufacturing, machine OEMs have generally taken the path of adding more lasers. nLIGHT takes the view that it’s not necessarily just more lasers that are needed, but beam-shaping lasers. By using dynamic beam shaping technology, significant increases in the productivity, stability and metallurgical capabilities of PBF-LB have been demonstrated. Given the technology’s recent commercial success, with adoption by Aconity3D, AMCM, EOS and DMG Mori, we asked the nLIGHT team to review beam shaping technology and its potential impact on the AM industry.

Additive Manufacturing is seen by the energy and maritime industries as having the potential to optimise supply chains and reduce the cost of spare parts through the use of ‘digital’ warehouses. The technology is used for both ‘like-for-like’ spare parts that were originally designed for machining, casting or forging, as well as new parts that have been optimised for AM. Here, Stian Saltnes Gurrik and Selin Erkisi Arici (DNV), and Onno Ponfoort and Mathijs van Poll (Berenschot), report on the latest findings of a Joint Industry Project that aims to understand the viability of such an approach in relation to a part’s carbon footprint.

In this joint study by Carl Zeiss AG, AMiquam SA, and EOS GmbH, the performance of eddy currents as a tool for the in-situ detection of defects in Laser Beam Powder Bed Fusion (PBF-LB) has been assessed. Process variations, including lack of fusion and keyhole formation could be detected in-situ, as well as individual defects as small as 0.3 mm post-build and post-polishing. Here, Jonatan Wicht, Harald Krauss, Frank Widulle, Julian Schulz, and Edson Costa Santos, Alain Berthoud, and Bernard Revaz present their latest findings.

For many decades, North America’s Metal Powder Industries Federation (MPIF) has organised its PM Design Excellence Awards competition in order to showcase the capabilities of the Powder Metallurgy industry. With the growing commercial success of metal powder-based Additive Manufacturing, the competition is seeing an ever larger number of entrants from this sector. Award-winning parts in this year’s competition include parts not only produced by Laser Beam Powder Bed Fusion, but also a wide range of innovative sinter-based AM processes.

China’s Additive Manufacturing industry is growing at extraordinary speed, driven forward by intense domestic competition and AM technology’s role in the country’s national manufacturing strategy. Based on a recent visit to the TCT Asia 2024 exhibition, Joseph Kowen shares an outsider’s perspective on what is happening in the Chinese metal AM industry. Are Chinese AM machines now rivalling those from the West in terms of capability, and how is an increasingly complex geopolitical situation impacting the dynamics of the AM industry?

The very existence of BMW Group’s state-of-the-art Additive Manufacturing Campus, located close to Munich, speaks volumes about the potential of AM technology in the automotive industry. In April, Metal AM magazine’s Technical Consultant, Martin McMahon, and Managing Editor, Nick Williams, had the opportunity to visit the campus. As is revealed here, they discovered an operation that not only functions as an application development centre and centralised location for the BMW Group’s AM expertise, but also operates as a model AM factory built around the concepts of productivity and automation.

Sustainability has risen to the top of the global manufacturing agenda. Whilst metal AM has long been considered a green technology because of its net-shape capabilities, it is far from being a process absent of environmental impact. Here, Martin McMahon explores how global efforts are being made to improve this through the use of more sustainable metal powders, combined with a greater focus on powder reuse and recycling. Inextricably linked to this are, of course, economic gains and, in terms of supply chain, national security benefits.
