Distortion in metal Additive Manufacturing: Modelling and mitigation
There is a growing recognition that software can play a vital role in determining the success or failure of Additive Manufacturing within an organisation. As Autodesk’s Michael Gouge and Pan Michaleris explain, metal AM is about far more than having the right machine or specifying the right material.
Dedicated AM software can today quickly and accurately simulate distortion in metal AM processes, significantly reducing build failure rates, minimising the associated economic impact and contributing to the enhancement of the technology’s reputation amongst end-users.

Materialise Magics: Advanced part orientation and support solutions to speed up application development
Materialise NV, headquartered in Leuven, Belgium, has more than 25 years of experience in developing industry-leading software for Additive Manufacturing. The company also operates some of the largest AM factories in Europe, including a metal AM facility in Bremen, Germany.
Kirsten Van Praet reveals how the latest release of the company’s Materialise Magics suite can help users achieve higher levels of AM production success through advanced part orientation and support solutions. Key advantages of the metal AM process are also reviewed through a case study and a number of application examples.

EOS GmbH: Transforming companies into AM champions with Additive Minds
EOS GmbH, based in Krailling, near Munich, has long been recognised as a leader in powder bed Additive Manufacturing technologies for both metals and plastics. The launch of its Additive Minds training and consultancy service, however, represents a significant expansion of the support that the company can offer to those entering the industry.
Nick Williams talks to EOS’s Güngör Kara, Director of Global Application & Consulting, on the evolution of the metal AM industry and the changing approach that customers are taking to implement the technology.

The science behind a basic consumer product: Bottle openers by metal Additive Manufacturing
Bottle openers manufactured by metal Additive Manufacturing have become a popular promotional gift, with a variety of designs produced by AM technology suppliers. In the first of a new series of design oriented articles for Metal Additive Manufacturing magazine, Olaf Diegel and Terry Wohlers reveal how these products effectively demonstrate several key concepts that designers need to understand in the development of parts for production by metal AM.

Accelerating AM component design workflow with new optimisation technology
Additive Manufacturing promises huge benefits for industry, but exploiting these in practice can prove difficult. For example, although truss-like component forms will often be found to be much more structurally efficient than traditional forms, identifying these has thus far been laborious and time-consuming.
However, a new optimisation approach means that engineers can now directly identify optimised truss forms for AM components, saving time and effort. Prof. Matthew Gilbert of LimitState and the Advanced Additive Manufacturing (AdAM) Centre at the University of Sheffield outlines the technology and its application.

Additive Manufacturing at World PM2016: Opportunities for the use of water atomised metal powders
At the World PM2016 Congress, held in Hamburg, Germany, 9-13 October, 2016, two papers discussed the potential for the replacement of gas-atomised powders with water-atomised powders as the raw material for Selective Laser Melting of different alloy types.
Dr David Whittaker reports on the work undertaken to assess the viability of the water atomisation process for these materials which could, in turn, offer significant cost savings.

Additive Manufacturing at World PM2016: Extending the range of materials in Powder Bed Fusion AM
Within the technical sessions dedicated to Additive Manufacturing research at the World PM2016 Congress a number of papers focused on materials new to Powder Bed Fusion and assessed the ability to process these materials.
Dr David Whittaker reviews three papers that report on investigations into Inconel 625 superalloy produced by EBM, Metal Matrix Composites with ceramic reinforcement and the direct metal printing of zinc.
