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.

As Additive Manufacturing shifts from process development and characterisation activities into the series production of components for critical applications, in-process quality control, qualification and certification are areas of fundamental importance to widespread adoption of AM [1,2]. In the following report, engineers from Sigma Labs, Inc., present the results of a study to establish a correlation between in-process data collected using the company’s PrintRite3D SENSORPAK® system and PrintRite3D INSPECT® software and the results of the metallographic testing of as-built specimens.
