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.

As Additive Manufacturing shifts from process development and characterisation activities into the series production of components for critical applications, in-process quality control, qualification and certification are areas of fundamental importance to widespread adoption of AM [1,2]. In the following report, engineers from Sigma Labs, Inc., present the results of a study to establish a correlation between in-process data collected using the company’s PrintRite3D SENSORPAK® system and PrintRite3D INSPECT® software and the results of the metallographic testing of as-built specimens.

The aerospace sector has been a key driver in the commercial development of metal Additive Manufacturing. Whilst some of the major application announcements of recent years can be looked back upon as milestones for the industry, numerous lower profile developments continue to demonstrate how metal AM has the capability to increase efficiency and add value in a multitude of application areas. We review a paper published in the Journal of the Minerals, Metals & Materials Society highlighting the potential for an innovative oil-gas separation rotor for aero-engine applications.
