Read the Spring 2019 issue of Metal Additive Manufacturing magazine

March 26, 2019

 

The Spring 2019 issue of Metal Additive Manufacturing magazine (Vol. 5 No. 1) has been released and is now available to read for free online or download in pdf format. In addition to the latest business and technical news, this 188-page magazine includes the following in-depth articles and technical reviews from the metal AM industry:

 

From rapid prototyping to rocket engines: The evolution of 3T Additive Manufacturing

With two decades of experience in part production using Additive Manufacturing technologies, 3T Additive Manufacturing Ltd, based in Newbury, UK, today enjoys a strong position as an international developer and supplier of cutting edge metal AM components.

At a time of transition for the company, Metal AM magazine’s Nick Williams and Emily-Jo Hopson met with outgoing CEO Ian Halliday and his successor, Nigel Robinson, to discuss the evolution of the metal AM industry to date and the business’s plans for further expansion.

 

Natural resources and national strategies: How metal Additive Manufacturing is taking off in Australia

Australian expertise is today becoming much more commonplace on the international AM scene. From technology and materials suppliers to application developers, companies are growing on the back of world-class research and education facilities, and a business environment where innovation and international trade are rewarded.

Combine this with an abundance of AM-relevant natural resources and, as Alex Kingsbury explains, an environment has been created in which AM is thriving.

 

Scalmalloy® is too expensive and design optimisation only makes sense in aerospace. True or false?

Additive Manufacturing is not a cheap production process. The software, machine time, materials and expertise required to make the most of the technology all come at a significant cost. The resulting financial pressures may give rise to the temptation to select a material on its price and view advanced topology optimisation as a luxury.

As Jon Meyer, APWORKS, and John Barnes, The Barnes Group Advisors, demonstrate, the unique capabilities of AM mean that basing material choice on cost without considering the impact of material performance on the mass of the part is a false economy, limiting the competitiveness of AM and the potential of an application.

 

Safety management in metal Additive Manufacturing: Observations from industry

In this article, UL LLC’s Balakrishnan V Nair discusses key safety issues in metal Additive Manufacturing, identifying some of the principal sources of risk associated with production operations and sharing safety concerns as encountered in UL’s work with metal AM clients globally.

In addition, Nair highlights some of the benefits that many AM facilities have enjoyed as a result of the successful implementation of sound safety practices.

 

Senvol: How machine learning is helping the U.S. Navy optimise AM process parameters and material performance

In a bid to better understand the impact of process parameters on material performance, the U.S. Navy turned to Senvol to develop data-driven machine learning software for Additive Manufacturing.

As Zach Simkin and Annie Wang explain, such an approach allows the user to overcome the time and expense required by a conventional trial-and-error process, whilst delivering remarkably accurate results that have the potential to accelerate application development.

 

Understanding build failures in Laser Powder Bed Fusion: An overview

Build failures remain a major challenge in metal Additive Manufacturing, particularly on large parts for which build times are measured in many days rather than hours. They come at a high price in lost machine time, wasted material and delayed deliveries.

Olaf Diegel and Terry Wohlers explain a number of reasons for such failures in Laser Powder Bed Fusion processes. In many cases, one can reduce their risk through effective part and support design, parameter control and machine maintenance.

 

MAMC2018: Vienna hosts ASMET’s third Metal Additive Manufacturing Conference

The third Metal Additive Manufacturing Conference (MAMC2018), organised by the Austrian Society for Metallurgy and Materials (ASMET) and voestalpine, took place in Vienna, Austria, from November 21–23, 2018.

The event, which attracted an international audience, covered a broad range of metal AM technologies and considered the technical challenges that need to be overcome to make the industry more economically competitive with conventional manufacturing.

Prof Dr Bruno Buchmayr, Dr Bruno Hribernik, Dipl-Ing Gerhard Panzl and Prof Dr Jürgen Stampfl review the event for Metal AM magazine.

 

Euro PM2018: The processing and properties of additively manufactured aluminium alloys

A technical session at the Euro PM2018 congress, organised by the European Powder Metallurgy Association (EPMA) and held in Bilbao, Spain, October 14–18, 2018, specifically addressed the processing and achievable properties of aluminium alloy parts built by Additive Manufacturing.

In this report, Dr David Whittaker reviews the four papers presented in this session.
