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]

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]

The past decade has seen tremendous growth in metal Additive Manufacturing. To a certain degree, the field has become a victim of its own success, resulting in a number of myths, misconceptions and untruths. Some of these are even becoming detrimental to the further adoption of AM around the world. Olaf Diegel and Terry Wohlers draw on their combined industry experience to address the ten most common misunderstandings and myths relating to AM and present the reality of the technology at its current stage [First published in Metal AM Vol. 4 No. 3, Autumn 2018]

Designing a component for AM whilst taking advantage of all the opportunities that the technology presents can result in many variables. Even a group of experienced Design for Additive Manufacturing (DfAM) experts will end up with significantly different build strategies for an identical part. In the following article, Olaf Diegel and Terry Wohlers consider how software innovations could further streamline the AM process, from part positioning and stress management to surface finish considerations and quality control

A number of factors drive the selection of process parameters in Laser Powder Bed Fusion (LPBF). In this invaluable resource Marc Saunders, Renishaw plc’s Director of Global Solutions Centres, details how these parameters define the ‘operating window’ in which AM users must work, and offers advice on identifying the ideal process parameters for metal AM parts. The sensitivity of the process to changes in part geometry is also considered, along with how this may drive part developers towards application-specific parameter choices [First published in Metal AM Vol. 4 No. 2, Summer 2018]

As the new Formula 1 season gets underway, Additive Manufacturing will have played a vital role in the development and manufacture of the cars on track. Metal AM magazine’s Nick Williams recently visited Sauber Motorsport AG at its headquarters near Zürich, Switzerland, and discovered how a partnership with Dutch AM technology supplier Additive Industries has supported both the development of in-house AM applications and an expansion of Sauber Motorsport’s AM services for third parties [First published in Metal AM Vol. 4 No. 1, Spring 2018]

Some companies approach Additive Manufacturing as a drop-in replacement for conventional manufacturing technologies. This approach, however, does not take into account the unique possibilities that additive processes offer and can result in parts that are not commercially viable due to cost. By designing parts specifically for AM, companies can reduce costs and improve efficiency while taking advantage of the possibilities offered by the technology. In this report, Olaf Diegel and Terry Wohlers look at the impact of good AM part design on machine operating costs [First published in Metal AM Vol. 4 No. 1, Spring 2018]
