The Spring 2020 issue of Metal Additive Manufacturing magazine (Vol. 6 No. 1) is now available to read online or download via our website or app (available on iOS and Android). This 184-page issue includes the following exclusive features:
Cheaper powders, faster build speeds and no thermal stresses? How AM is going supersonic at SPEE3D
In recent years, Australia’s SPEE3D has made waves in the AM industry with its Cold Spray-based metal Additive Manufacturing systems. Following successful projects with the US and Australian military, and multiple installations at one of Europe’s most experienced metal AM parts manufacturers, the world is starting to take note.
Alex Kingsbury visited the company at its Melbourne base for Metal AM magazine and spoke with its founders and newly expanded management team about its technology and international expansion.
Current perspectives on metal AM: Hype, volume manufacturing and the geographies of production
Metal AM exists in a potentially confusing place between the world of 3D printing and its ‘maker’ movement, and Industry 4.0, with its drive towards new economic models.
Here, Dr Jennifer Johns, Reader in International Business at the University of Bristol, UK, contextualises metal AM within broader narratives around technological change and economic development, Industry 4.0 and the Factory of the Future to give us a better understanding of what the outside world expects.
Drawing on recent empirical research, different and often contradictory viewpoints are presented on the key issues facing the move to volume manufacturing and the geographies of production.
AM Ventures: An insider’s perspective on venture capital for start-ups in Additive Manufacturing
In an industry driven by innovation, start-ups play a vital role in creating the next generation of AM technologies, applications, software solutions and materials. However, only a small percentage of these start-ups will survive, and even fewer will thrive.
Arno Held, Chief Venture Officer at AM Ventures Holding GmbH, presents a statistical analysis of start-ups across the AM sector, including success rates, geographic distribution and key areas of focus, and offers his insight into venture capital as it relates to the Additive Manufacturing industry.
Binder Jetting and beyond: Optimising the use of metal powders for Additive Manufacturing
The high cost of metal powders for Additive Manufacturing makes them a primary focus for cost management. Learning how to treat and store such powders in order to maintain and optimise their performance and value is one way to improve production economics.
Here, Dr Rajeev Dattani, from Freeman Technology, UK, and Dr Animesh Bose, Desktop Metal, USA, review how to test powders in order to develop this knowledge, and examine treatment and storage regimes that can be beneficial.
From lightweighting and material efficiency to energy consumption: Where are we on AM’s sustainability journey?
Additive Manufacturing has been heralded as a game-changing technology of the future. But while many ‘green’ and ecological initiatives have bloomed from the AM movement, the question remains: “Is AM environmentally friendly?”
As Olaf Diegel, Ray Huff, and Terry Wohlers explain, the short answer is: it can be, in the hands of good designers and well-informed manufacturers. As with any tool or process, knowledge and experience are key. It is important to explore the many ways AM is applied in sustainable ways and whether it is improving.
AM’s industrial impact celebrated as Sweden hosts ASMET’s fourth Metal Additive Manufacturing Conference
The fourth Metal Additive Manufacturing Conference (MAMC 2019), organised by the Austrian Society for Metallurgy and Materials (ASMET), took place in Örebro, Sweden, from November 25–27, 2019.
The event, which attracted an international audience, covered a broad range of metal AM technologies and considered the technical challenges that need to be overcome to make the industry more economically competitive with conventional manufacturing.
Prof Dr Jürgen Stampfl, Prof Nader Asnafi, Dr Bruno Hribernik, and Dr Gerhard Hackl review the event for Metal AM magazine.
Euro PM2019: Effects of humidity and storage conditions on Additive Manufacturing powder quality
A technical session at the Euro PM2019 Congress, organised by the European Powder Metallurgy Association (EPMA) and held in Maastricht, the Netherlands, October 13-16, 2019, focused on the impact of storage conditions, particularly exposure to humidity, on the characteristics and quality of powders used in Powder Bed Fusion Additive Manufacturing.
Dr David Whittaker reviews selected papers presented during this session.
