Simple and standardised X-ray CT testing in metal Additive Manufacturing

X-ray Computed Tomography (CT), also widely known as MicroCT, is a proven method for not only checking the structural integrity of additively manufactured (AM) parts – for example for unwanted porosity – but also for checking a build’s dimensional accuracy. The main advantage of the technique is of course the non-destructive nature of the assessment; however, there are also many misunderstandings about the capabilities and complexity of the technology. Prof Anton du Plessis and Dr Jess M Waller review the application of CT testing in relation to metal AM and highlight the advantages of a move towards standardised test methods [First published in Metal AM Vol. 4 No. 4, Winter 2018] ...

Formnext 2018: The global AM industry addresses ‘the bigger picture’ for true industrialisation

From November 13-16, 2018, the Additive Manufacturing world congregated in Frankfurt, Germany, to attend the year’s final and arguably most significant international exhibition on the technology. Occupying more than 37,000 m2 of floor space, Formnext 2018 attracted nearly 27,000 visitors – an increase of more than 25% on the previous year – and over 600 global exhibitors. In this report, Metal AM’s Emily-Jo Hopson covers some of the news and developments out of Formnext, and looks at how they reflect an industry turning its focus toward productivity and efficiency for true industrialisation [First published in Metal AM Vol. 4 No. 4, Winter 2018] ...

Formnext 2018: International forum reviews standards for Additive Manufacturing

Organised by the U.S. Commercial Service in Dusseldorf, Germany, the Additive Manufacturing/3D Printing Standards Forum took place on November 14, 2018, in Frankfurt, Germany, at the Formnext trade fair. As Dr Georg Schlieper reports, the event brought together leading experts from industry, research institutions, standards developing organisations, professional societies and government to address key themes focused on standards development in AM technologies. This included progress on international standards development for AM and how the use of these standards can help the industry achieve its potential [First published in Metal AM Vol. 4 No. 4, Winter 2018] ...

How residual stress can cause major build failures, and what you can do to prevent it

Anyone who starts out on their own evaluation of the opportunities presented by metal Additive Manufacturing will soon stumble across the phrase ‘build failure’. Whilst there can be many causes for a failed build, which of course comes at a significant cost in terms of both material wastage and machine time, residual stress is often at the top of the list. As Olaf Diegel and Terry Wohlers explain, residual stress can be both anticipated and managed though a combination of basic design rules, process settings and post-build heat treatment [First published in Metal AM Vol. 4 No. 4, Winter 2018] ...

Additive Manufacturing in Aerospace: Highlights from the AMA 2018 international conference in Bremen

Much of metal Additive Manufacturing’s recent success has been driven by the aerospace sector, where demanding applications have propelled progress in all aspects of the technology, from process stability and quality to part design and materials. Together, these advances are enabling metal AM to meet the next challenge: that of wider serial production. As the University of Bremen’s Christian Kober reports, it was this challenge that formed the central theme at this year’s International Conference on Additive Manufacturing in Aerospace [First published in Metal AM Vol. 4 No. 4, Winter 2018] ...

Siemens: Digitalisation enables the industrialisation of metal Additive Manufacturing at Finspång

As one of the world’s largest industrial companies, Siemens has experienced first hand the process of taking metal AM from the R&D laboratory to the series production of critical components for its power generation business. Today, it is supporting the global industrialisation of the technology through its Siemens NX Additive Manufacturing software. In the following report the company’s Aaron Frankel and Ashley Eckhoff explain their belief that, whilst the potential of AM is massive, digitalisation will play a critical role in enabling its transition from a prototyping tool to a serial production technology [First published in Metal AM Vol. 4 No. 3, Autumn 2018] ...
