Scalmalloy is too expensive and design optimisation only makes sense in aerospace. True or false?
Additive Manufacturing is not a cheap process and this can give rise to the temptations to select a material on price alone and view advanced topology optimisation as a luxury. Here, Jon Meyer and John Barnes demonstrate that the unique capabilities of AM mean that basing material choice on cost without considering the impact of material performance can limit the competitiveness and potential of an application.

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, thanks in part to world-class research and education facilities, and a business environment where innovation and international trade are rewarded. Combine these with an abundance of natural resources and, as Alex Kingsbury explains, an environment has been created in which AM is thriving. Go to article…
Digitalisation enables the industrialisation of metal Additive Manufacturing at Finspång
As one of the world’s largest industrial companies, Siemens has experienced first hand the process of taking metal AM from the R&D laboratory to the series production of critical components for its power generation business. Aaron Frankel and Ashley Eckhoff explain that, whilst the potential of AM is massive, digitalisation will enable its transition to a serial production technology. Go to article…

Thinking about metal Binder Jetting or FFF? Here is (almost) everything you need to know about sintering
With the arrival of high-volume metal Binder Jet systems and a growing interest in metal Fused Filament Fabrication, the AM industry is set for a new phase of growth. The ability to use this new generation of systems for the production of ‘green’ parts is, however, only half of the story. The sintering of these parts to create large quantities of finished product to a consistent quality requires both an investment in furnaces that can cost in excess of $1 million each, and a thorough understanding of sintering. In this article, Prof Randall German, the leading authority on the science of sintering, outlines the process and its core challenges.
