Since the first conference on electron beam Additive Manufacturing in Nuremberg in 2016, the EBAM conference series has been the central meeting point for industry and academia to exchange knowledge on this dynamic area of AM. After the event was forced to go virtual in 2020 due to COVID-19, attendees were finally able to meet face-to-face again in Erlangen, March 22-24. Marie Franke-Jurisch and Dr Matthias Markl report on recent developments in materials, process, and machine technology, all of which serve to demonstrate that electron beam-based technologies are once again firmly established in the metal Additive Manufacturing world.

Binder Jetting’s position as an accepted mass production technology for precision metal components is on the near horizon. The coming success will, however, rely as much on expertise in the sintering process as it does on expertise in jetting binder onto a powder bed to make ‘green’ parts. This article reports on how GKN Powder Metallurgy’s Additive Manufacturing division, GKN Additive, has leveraged decades of sintering expertise in high-capacity continuous furnaces, combined with its application development expertise, to deliver the series production of special filters by Binder Jetting for Schneider Electric.

Two worlds collide in Additive Manufacturing. Consider that a Laser Beam Powder Bed Fusion (PBF-LB) machine completes its job fully automatically over many hours. Yet, before and after that, a multitude of manual tasks often still need to be completed. Employees may be required to perform these tasks while wearing personal protective equipment (PPE) to protect themselves from metal dust, compounded by the high labour costs that this manual work incurs. Is this the future of cost-efficient, 24/7 production? Christian Mittmann and Manuel Henser, from Volkmann GmbH, believe that the real solution can be found in the complete automation of powder handling.

Kennametal is a particularly interesting company when it comes to the adoption of Additive Manufacturing. It is a dynamic global producer of tooling and industrial materials with sales of $2 billion in 2022, yet its roots are very much in ‘old school’ sinter-based PM processes. It is, therefore, no surprise that the company was an early adopter of AM, leveraging its materials and sintering expertise, as well as its broad customer base, to develop a leading position in the AM of hardmetals and steels. Bernard North, who fortuitously happens to be a past VP Industrial Technology at Kennametal, visited the company’s AM operation and reports for Metal AM magazine.

Three years ago, Metal AM magazine published a widely read article on the use of Laser Beam Powder Bed Fusion (PBF-LB) technology for precious metal jewellery production. Today, the continuing rise of sinter-based AM technologies promises to open up the jewellery sector yet further, with new opportunities for both mass-market production as well as bespoke pieces. Chiara Armbruster, Sonja Kappler, Carlo Burkhardt, Gerald Mitteramskogler and Apollinaria Frydmann offer an overview of this new generation of solutions and the state of the technology. A number of application examples are also presented.

The Additive Manufacturing industry is in a state of continual evolution. As one group of processes moves towards widespread adoption, others are being introduced and refined. In such a dynamic environment, how do we define AM, and what does ‘good’ AM look like? This article considers the status quo of conventional manufacturing before comparing key AM processes. Steven Camilleri, Andrew Duguid, Sam Katz and Chris Massar (SPEE3D), Martin McMahon (MAM Solutions), Victor Champagne (US Army Research Laboratory), Ozan Özdemir (Northeastern University), Anthony Naccarelli and Timothy Eden (Penn State), Krishnan Kannoorpatti (Charles Darwin University) and Bruce McLean (University of Sydney) unravel AM’s value metrics.

In the race to optimise AM technologies for the creation of both breakthrough designs and direct part replacements, it is more necessary than ever that companies have access to the deep insights and data needed to advance part designs and processing at every phase of product development. Thanks to its ability to provide these insights non-destructively and in great detail, CT analysis provides an invaluable tool for the advancement of AM processes and their adoption. Philip Sperling, Product Manager AM at Volume Graphics, explains how CT analysis can advance the development and adoption of metal Binder Jetting (BJT).

In Laser Beam Powder Bed Fusion (PBF-LB), powder is applied to the build platform by a recoater unit performing a horizontal movement. Though not often the focus of research, the quality of powder layers has a significant influence on the quality of the final part, making the powder application process highly relevant to PBF-LB’s productivity and reliability. A collaborative project between the Chair of Hybrid Additive Manufacturing (HAM) at the Ruhr University Bochum and the consulting firm MTS Consulting Partner has shown how the Six Sigma method can be used to improve the process of metal powder application in the PBF-LB process.

When NanoAL, LLC, a company with a decade of aluminium alloy development experience, decided to speed up its development of alloys for AM, it turned to SLM Solutions’ SLM®125 PBF-LB machine. As NanoAL’s Matthew Simmers explains, the company needed a workhorse machine that fulfilled a number of requirements, from open parameters and material flexibility to specifications and build quality that closely mirrored larger, production-focused machines. This article explores machine choice, installation, and operation in supporting NanoAL’s Rapid Alloy Screening (RAS) process.

Alloy development has evolved dramatically throughout history, from what was a game of ‘trial and error’ to a systematic approach driven by Design of Experiments and specialist software. Now, the adoption of Integrated Computational Materials Engineering (ICME) is once again changing the way new materials are developed and deployed in today’s advanced manufacturing technologies. QuesTek’s Keith Fritz, Director of Solutions Architecture, details how the company’s ICMD® platform is enabling faster, cheaper and more successful development of new alloys for metal Additive Manufacturing, as well as the build parameters to process them.

The use of metal AM is ramping up, and so, as a result, is the demand for metal powders. However, the variety of materials available remains relatively small. This is due, among other things, to the exacting requirements for the powders used, and the method of production. In addition, the production of smaller quantities of powder can be uneconomical. In a project funded by the AiF, the IWM at Germany’s RWTH Aachen University and Fraunhofer IFAM have developed a sustainable ‘powder kit’ for the individual and robust production of metal powder mixtures with subsequent alloying during PBF-LB processing. The partners share their progress.

Additive Manufacturing processes offer a high degree of design freedom. The Laser Beam Powder Bed Fusion of metals (PBF-LB/M), in particular, has established itself for series applications of complex-shaped parts in numerous industries. In this article, Prof Dr-Ing Christian Seidel considers the next major step in PBF-LB, which could offer designers unknown potential: the production of sensor-integrated AM parts. Methods and solutions for the manufacturing of sensor-integrated AM parts are presented and industry-relevant case studies showcased, illustrating the potential offered by sensor-integrated ‘smart parts.’
