A technical session at the Euro PM2017 conference, held in Milan, Italy, October 1-5, 2017, investigated three different concepts in processes that combine metal Additive Manufacturing with Hot Isostatic Pressing (HIP). In the following report, Dr David Whittaker reviews three papers that consider the use of SLM for the manufacture of HIP capsules, HIP as a final densification process in AM, and finally HIP as a process to join EBM processed components into larger structures [First published in Metal AM Vol. 3 No. 4, Winter 2017]

Making the investment in a metal Additive Manufacturing machine is, for many, the first step on a journey to truly understanding how the technology can transform a business. There are, however, many considerations when planning such an investment; from essential ancillary equipment and devices, such as sieving stations, to facility changes, software and support. In this exclusive report, Terry Wohlers and Olaf Diegel highlight some of the commonly overlooked costs and considerations when making the move to establish an in-house AM capability [First published in Metal AM Vol. 3 No. 4, Winter 2017]

In recent years much effort has been put into developing powders that are optimised for AM processes. As a result, a far greater understanding of the complex requirements for powders now exists. Particle size is widely recognised as a key property, but there is also an appreciation that particle shape has an important role to play. As Malvern Panalytical’s Debbie Huck-Jones and Cathryn Langley, explain, finer particles are advantageous from the perspective of packing behaviour, but are typically associated with poor flowability, compromising processing efficiency. Controlling particle shape can help to alleviate this problem [First published in Metal AM Vol. 3 No. 4, Winter 2017]

Paying the right amount of attention to Design for Additive Manufacturing (DfAM) can make the difference between economic success and failure. When considering Additive Manufacturing for production applications, it is important to consider designing, or redesigning, parts that would otherwise be produced using conventional manufacturing. In this case study, Terry Wohlers and Professor Olaf Diegel, both of Wohlers Associates, reveal how industrial mining machine manufacturer Atlas Copco has used DfAM to increase the value of a hydraulic manifold [First published in Metal AM Vol. 3 No. 3, Autumn 2017]

Additive Manufacturing presents the opportunity to completely rethink a product’s design, transforming its functionality and reducing manufacturing complexity. With the right application and the right approach, the results really can live up to industry buzzwords such as ‘disruptive’ and ‘transformational’. In the following article, Optisys LLC reveals how, through intelligent design optimisation, the company has used Additive Manufacturing to develop the next generation of RF antenna systems for aerospace and defence [First published in Metal AM Vol. 3 No. 3, Autumn 2017]

An issue of significant current interest to the AM world, which can potentially impact both the quality and cost-effectiveness of built parts, is whether there is a limit on the number of times that metal powders can be cycled around an AM process. In this article, Dr David Whittaker reviews three presentations on the topic from AMPM2017, the fourth annual Additive Manufacturing with Powder Metallurgy Conference, held in Las Vegas, USA, June 13-15, 2017 [First published in Metal AM Vol. 3 No. 3, Autumn 2017]
