Oerlikon: Swiss industrial group positions itself as a leading developer of AM components and materials
Over a period of just twelve months, Switzerland’s Oerlikon Corporation AG has made a major move into the world of Additive Manufacturing. Through a combination of acquisitions and new facility investments, the company has established itself as a leading international developer of both AM materials and components, offering its customers the complete process chain, from new alloy development to component post-processing and testing. Metal AM magazine’s Nick Williams reviews the company’s progress to-date.

The 1st Munich Technology Conference: AM is on course for broad industrial use
More than 600 international metal AM professionals gathered in October for the 1st Munich Technology Conference. Organised and sponsored by Oerlikon, the aim of this unique event was to provide a dedicated platform for the discussion and sharing of best practices in AM production and applications, along with the business models needed to drive the industrialisation of AM.
We invited Prof Dr-Ing Michael Zäh, Chair of Machine Tools and Production Technology at the Technical University of Munich, to consider the status of metal AM as revealed over the event’s two days of presentations and discussions.

Combining Metal AM and Hot Isostatic Pressing (HIP): Application and process innovations
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.

Costs and considerations when investing in a metal Additive Manufacturing system
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.

Beyond particle size: Exploring the influence of particle shape on metal powder performance
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.

POWDERMET2017: Developments in powder production methods for AM
In addition to the parallel Metal Powder Industries Federation’s AMPM2017 conference, the programme for the POWDERMET2017 International Conference on Powder Metallurgy & Particulate Materials, Las Vegas, June 13-16, 2017, included technical sessions on AM.
Two of these sessions were devoted to powder production methods for AM feedstocks and this report from Dr David Whittaker reviews three selected papers in this subject category.
