The Additive Manufacturing of light alloys was the focus of three separate technical sessions at the World PM2016 Congress, held in Hamburg, Germany, from 9-13 October, 2016. The event, which was organised by the European Powder Metallurgy Association (EPMA), covered all aspects of metal powder processing technologies. This report reviews three of the key papers from these sessions, two relating to the AM of aluminium alloys and the third to the AM of a magnesium alloy. ... Read more »
In the second of our reports from the Metal Powder Industries Federation’s Additive Manufacturing with Powder Metallurgy (AMPM) conference, Dr David Whittaker reports on three presentations that highlighted developments in the processing of novel AM materials. These include tungsten for nuclear fusion applications and copper alloys for applications which require high electrical conductivity. ... Read more »
In part two of our report on technical advances in metal AM at the Euro PM2015 Congress, Reims, France, October 4-7 2015, Dr David Whittaker reports on six further papers presented at the conference’s very well attended metal AM sessions. These papers cover the heat treatment of IN939 superalloy parts, the production of Ni718 superalloy powder, advances in inkjet-based metal AM and the production of gears by Laser Metal Deposition (LMD). ...

The high cost of metal powders for Additive Manufacturing makes them a primary focus for cost management. Learning how to treat and store such powders in order to maintain and optimise their performance and value is one way to improve production economics. Here, Dr Rajeev Dattani, from Freeman Technology, UK, and Dr Animesh Bose, Desktop Metal, USA, review how to test powders in order to develop this knowledge, and examine treatment and storage regimes that can be beneficial.

This is a challenging and exciting time for producers of metal powders. Talk of the industrialisation of Additive Manufacturing is everywhere and key pieces of the AM jigsaw such as standards, quality systems and installed production capacity are falling into place. The nature of the companies which are looking to take advantage of the anticipated feast is, however, surprisingly diverse. In this article, Alex Kingsbury and Dayton Horvarth highlight how long-established metal powder giants are adapting to AM and how agile start-ups are carving out niches in the powder marketplace.

There is no shortage of Additive Manufacturing machines humming away in research laboratories, producing test pieces and exhibits for trade shows, but the hard truth is that relatively few are making components for serial production. In part, this is because the world is still waiting for materials which enable the technology to fulfil its true potential. In this article, Rebecca Gingell and colleagues from OxMet Technologies, Oxford, UK, explain how the company is approaching the design of novel alloys for AM, and reflect on its progress so far.
