The AMPM conference series, sponsored by the Metal Powder Industries Federation (MPIF), was initiated in 2014 and ran in parallel with the PM2014 World Congress in Orlando, Florida. The second conference in the series was held in San Diego, California, from May 17-20, 2015. In this exclusive report for Metal AM magazine Dr David Whittaker reviews a number of key papers from the conference, ranging from a presentation on the activities of America Makes to developments in the production and characterisation of metal powders for AM.

More than 150 participants from 19 countries attended the Metal Additive Manufacturing Conference (MAMC), Vienna, November 20-21, 2014. The conference, organised by the Austrian Society for Metallurgy and Metals (ASMET) and voestalpine Edelstahl, reviewed the latest developments along the entire processing chain as well as novel applications. Prof. Bruno Buchmayr, Montanuniversität Leoben, and Prof. Juergen Stampfl, TU Wien, present an introduction to Additive Manufacturing and report on highlights from the MAMC 2014 conference.

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.

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.

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.

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.

Now in its third year, the Munich Technology Conference series has achieved a remarkable status in its short history. It is recognised not only for bringing together the most powerful and influential minds in the international AM community, but for engaging them in open and broad-ranging discussions on the future of the industry. It is also an event that unashamedly ‘wears its heart on its sleeve’, having grown from the optimism of MTC1 to MTC2’s call for vital collaboration, and a ‘reality check’ in the face of economic uncertainty at MTC3. Metal AM magazine’s Emily-Jo Hopson reports. [First published in Metal AM Vol. 5 No. 4, Winter 2019]

Metal Additive Manufacturing is a complex technology in which users struggle with materials reliability and quality on a daily basis. Here, William Herbert, Director Technology and R&D – Carpenter Additive, a division of Carpenter Technology, looks at how the company combines a 130-year heritage as a leader in speciality alloys with modern, digital solutions for powder management and material traceability, and supports the AM supply chain end-to-end by developing advanced materials, improving process economics and quality, and reducing risk in production applications.

This is a challenging and exciting time for producers of metal powders. Talk of the industrialisation of Additive Manufacturing is everywhere and key pieces of the AM jigsaw such as standards, quality systems and installed production capacity are falling into place. The nature of the companies which are looking to take advantage of the anticipated feast is, however, surprisingly diverse. In this article, Alex Kingsbury and Dayton Horvarth highlight how long-established metal powder giants are adapting to AM and how agile start-ups are carving out niches in the powder marketplace.

There is no shortage of Additive Manufacturing machines humming away in research laboratories, producing test pieces and exhibits for trade shows, but the hard truth is that relatively few are making components for serial production. In part, this is because the world is still waiting for materials which enable the technology to fulfil its true potential. In this article, Rebecca Gingell and colleagues from OxMet Technologies, Oxford, UK, explain how the company is approaching the design of novel alloys for AM, and reflect on its progress so far.

Additive Manufacturing is arguably the ideal production method for numerous aerospace applications, particularly where lightweighting and part consolidation are concerns – yet no other industry takes such a cautious approach to embracing new manufacturing methods and imposes so many hurdles on the path to certification. In this article, Germany’s Trumpf GmbH + Co. KG tracks the production journey of one part for Spain’s Ramem S.A., as well as looking at further cases from the aerospace industry.

In powder bed Additive Manufacturing processes, the recoater system is responsible for spreading a fine and even layer of powder for each layer of a build. This system typically uses wipers to create the necessary surface, with the variants of wipers used being almost as diverse as the number of AM machines on the market. Olaf Diegel and Terry Wohlers explain why it is not only machine operators, but also designers and engineers, who need to be aware of the weird and wonderful world of wipers.
