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] ...

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] ...

Metal Additive Manufacturing in China: An overview of systems manufacturers

What’s happening in metal Additive Manufacturing in China? Quite a lot it seems; however, the extent and nature of this activity, and what can be expected from Chinese systems manufacturers in the coming years, can be unclear to Western observers. In the following report, Joseph Kowen offers a brief look into the current state of the metal AM industry in China. As well as presenting an overview of machine-related activity in this fast growing part of the world, he considers to what extent we can expect to see an increased presence of Chinese suppliers in western countries [First published in Metal AM Vol. 4 No. 3, Autumn 2018] ...

Binder Jetting and FDM: A comparison with Laser Powder Bed Fusion and Metal Injection Moulding

In recent years there has been a surge in interest in the use of Binder Jetting and Fused Deposition Modelling for the production of low to medium volumes of metal additively manufactured parts. In the following report, Maximilian Munsch, Matthias Schmidt-Lehr and Eric Wycisk of Ampower GmbH & Co KG, Hamburg, Germany, review how the success of Metal Injection Moulding has enabled these technological innovations. They also compare some of key properties and costs to enable designers to better understand the readiness of these technologies for commercial production [First published in Metal AM Vol. 4 No. 3, Autumn 2018] ...

Metal Additive Manufacturing: A simulation provider’s perspective

Over the past few years, metal Additive Manufacturing has received a lot of attention, and with good reason: the technology has the potential to radically alter the design and production of components and products in many industries. Yet in spite of the excitement that surrounds AM, the prospect of wider industrial adoption continues to face significant challenges. Ansys Inc’s Dave Conover explains how simulation, traditionally the domain of product design instead of manufacturing, has swiftly gained recognition as a key technology which can be used to ease the transition from conventional to Additive Manufacturing [First published in Metal AM Vol. 4 No. 3, Autumn 2018] ...
