Mauro Antolotti and BEAMIT:
The story of Italy’s leading AM parts producer and its founder’s view on the industry
From machine producers to part manufacturers and end-users, the Additive Manufacturing industry is rich in success stories that are the result of one person’s vision of what the technology could deliver. In the case of BEAMIT, Italy’s largest metal AM parts producer, it was the vision of the company’s founder, Mauro Antolotti.
Here, Luca van der Heide interviews Antolotti for Metal Additive Manufacturing magazine and explores the company’s development, his view of the industry, and ambitions for the future.

Why do we need Women in 3D Printing?
The what, the who, and the why of the blog that became a movement
Since 2014, Women in 3D Printing has grown to become a highly visible and influential international organisation. But what does the movement stand for, why is it proving to be so popular, and where does it go from here?
Metal AM magazine’s Emily-Jo Hopson-VandenBos spoke with the group’s founder, Nore Toure, and fifteen members about their views of the organisation and the current status of women in the industry. These conversations reveal not only the challenges that we face to improve diversity in its broadest sense, but also the tangible benefits that members are seeing at both the personal and organisational level.

The need for speed, and how the right powder can reduce AM part production costs by 50%
If metal Additive Manufacturing is to compete with casting and other mass-production technologies, costs need to be reduced by a factor of ten. Optimising metal powder characteristics can get the industry halfway there, while anticipated improvements in equipment and processes will do the rest.
Here, Equispheres’ Doug Brouse and Dr Martin Conlon discuss how the use of advanced aluminium powders can improve the build rate for Laser Beam Powder Bed Fusion (PBF-LB) by two to four times, as well as offering significant advantages for Binder Jetting (BJT) production

Metal Additive Manufacturing:
Why standards lay the foundation for continued industry growth
As the metal Additive Manufacturing industry evolves towards widespread use for series production, the need for globally-recognised standards is also increasing.
In this article, Prof Dr-Ing Christian Seidel, Chairman of ISO Technical Committee (TC) 261 ‘Additive Manufacturing’ and Member-at-Large on the Executive Committee of the ASTM F42 ‘Additive Manufacturing’ Committee, outlines why standards are so important, presents an overview of the current AM standards ecosystem, and highlights current key areas of standardisation activity.

The advantages of Additive Manufacturing for the processing of platinum group metals
There is growing interest in the use of metal Additive Manufacturing for the production of jewellery and luxury watch components. This interest is driven not only by the potential design innovation offered by Additive Manufacturing, but also by the recognition of the environmental and economic advantages to be gained from it. In this in-depth report, Jochen Heinrich, Thomas Laag and Thierry Copponnex review the processing of platinum group metals by Additive Manufacturing.

Obstacles to the adoption of metal AM by small- and medium-sized enterprises
It is no secret that metal Additive Manufacturing still faces significant challenges that stand in the way of broader adoption in industry. Aside from AM service providers, very few small- to medium-sized enterprises have brought metal AM in-house; many lack the capabilities, knowledge and resources to do so, even if the will is there.
In this article, Olaf Diegel and Terry Wohlers discuss the complex, and often multi-faceted, obstacles that stand between AM and its wider global adoption, and how those obstacles can be addressed and resolved in order to clear the path to achieving the technology’s full market potential.
