As the metal Additive Manufacturing industry matures at a rapid rate, organisations are now faced with the challenge of scaling their AM operations. Based on a study of 253 companies in a number of sectors, US-based AM software specialist Link3D has developed an ‘Additive Manufacturing Maturity Model’. This simple model can be used as a tool to understand an organisation’s AM maturity whilst also helping them navigate the steps to developing an agile and resilient AM supply chain. Shane Fox, CEO and co-founder of Link3D, explains. [First published in Metal AM Vol. 6 No. 2, Summer 2020]

Just as Design for AM demands an entirely new mindset to be truly effective, understanding efficient AM machine utilisation in order to drive profitability also requires a major shift from conventional practices. In this article, Magnitude Innovations Inc’s Matt Tusz, Founder and CEO, and Caterina Pampolari, Business Development Manager, explore operational and financial losses in metal Additive Manufacturing. They offer advice on how to overcome these growth barriers through production efficiency and profitable pricing strategies, with a focus on Operational Excellence and Continuous Improvement.

Laser Beam Powder Bed Fusion (PBF-LB) is a technology rich in process parameters and exacting material specifications, all developed with the aim of delivery quality and repeatability as the industry moves towards volume production. However, without control of a laser’s focal spot, neither the material specification nor the handling of the material in the build chamber can guarantee the hoped-for results. As Ophir Spiricon Europe’s Christian Dini explains, when it comes to lasers, there is no control without the gathering of reliable data. [First published in Metal AM Vol. 6 No. 2, Summer 2020]

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.

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.

During the Euro PM2019 Congress and Exhibition in Maastricht, the Netherlands, this October, a number of Special Interest Seminars were held focusing on various aspects of the Powder Metallurgy and Additive Manufacturing industries. In one seminar, Dr Uemit Aydin, GKN Additive, and Nicholas Turner, Materials Solutions, looked to the future of Additive Manufacturing and expressed their views on its industrialisation. David Whittaker attended the SIS on behalf of Metal AM magazine and reports on its conclusions.[First published in Metal AM Vol. 5 No. 4, Winter 2019]

The wide potential of Additive Manufacturing in the oil and gas and maritime sector has come to be widely accepted, with the technology offering significant advantages in terms of lead time, part weight, part count, higher levels of geometric complexity and new material properties. However, in these safety-critical industries, there remain some concerns regarding the quality of AM parts. A Joint Industry Project (JIP), begun in January 2018 and consisting of twenty partners, aims to deliver a new JIP Guideline on Additive Manufacturing for this sector. Here, DNV-GL’s Harsharn Singh Tathgar and Berenschot’s Onno Ponfoort report on the guideline’s development. [First published in Metal AM Vol. 5 No. 3, Autumn 2019]

On July 4, 2019, Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) sponsored and co-organised a one-day symposium in Melbourne entitled ‘Towards a True Digital Twin’. The event, which followed APICAM 2019, the 2nd Asia-Pacific International Conference on Additive Manufacturing, brought together experts in a range of relevant fields including metal Additive Manufacturing, computational modelling, multi-scale techniques, structure-property relations, machine learning and artificial intelligence, and digital twins of industrial processes. Here, CSIRO Manufacturing’s Dr Dayalan Gunasegaram and Dr Tony Murphy consider the importance of the digital twin in AM and report on some of the event’s key findings.

At the 2019 Additive Manufacturing Users Group (AMUG) Conference in Chicago, Illinois, a panel was held to discuss requirements for Additive Manufacturing systems. Despite the late hour of the panel and depth in the week at which it was held, a formidable crowd organised themselves to hear Ryan Dehoff of ORNL, Filip Francqui of Granutools and John Barnes of The Barnes Group Advisors discuss the topic of powder in AM. In this article, the panellists explore in more detail the differences in powder requirements between AM systems.

Whilst the principles of Design for Additive Manufacturing (DfAM) may suggest ‘clean-sheet’ components are the best way to reap the benefits of AM technology, many examples of redesigns have brought significant performance and economic benefits. In this article, Ray Huff and Terry Wohlers report on further success at Siemens in the use of AM for gas turbine fuel swirlers, highlighting both the development process and the evolving role of digital data in manufacturing.
