Strategies for advancing the automation of metal Additive Manufacturing

In the early days of metal Additive Manufacturing process development, automation was off the radar of machine manufacturers. Technologies created for rapid prototyping simply had no need for it and, until the last decade, few truly anticipated the pace at which Laser Beam Powder Bed Fusion and Binder Jetting have evolved in the race towards the series production of metal parts. In this article, Joseph Kowen reports on how the industry has addressed the challenges of automation so far, and what developments we can expect in the near future.

Machine Learning and Additive Manufacturing: What does the future hold?

As industry marches toward automation, networked communication and robotics, Additive Manufacturing has a unique advantage. No other production technology has been designed, from its inception, to enable connectivity and communication; AM machines around the world are already producing more build data than any other manufacturing technology. If used properly, this data will provide the foundation for the development of Machine Learning tools that can improve and industrialise the AM process at nearly every point in the workflow. In this article, Chelsea Cummings and John Barnes, from The Barnes Global Advisors, discuss the present and future of Machine Learning in AM.

CFD simulation for metal Additive Manufacturing: Applications in laser- and sinter-based processes

Computational Fluid Dynamics (CFD) is widely applied to solve a broad range of research and engineering problems, from aerodynamics to engine combustion and microfluidics. In this article, Pareekshith Allu, Senior CFD Engineer at Flow Science, Inc, explains how CFD can also be used to improve laser- and non-laser-based metal Additive Manufacturing processes, including Laser Beam Powder Bed Fusion (PBF-LB), Directed Energy Deposition (DED), Binder Jetting (BJT) and Material Extrusion (MEX).

Alloys by Design: The future of materials for Additive Manufacturing

There is no shortage of Additive Manufacturing machines humming away in research laboratories, producing test pieces and exhibits for trade shows, but the hard truth is that relatively few are making components for serial production. In part, this is because the world is still waiting for materials which enable the technology to fulfil its true potential. In this article, Rebecca Gingell and colleagues from OxMet Technologies, Oxford, UK, explain how the company is approaching the design of novel alloys for AM, and reflect on its progress so far.

Defining your digital future: The path to industrial digitalisation in Additive Manufacturing and beyond

Terms such as Industry 4.0, the Digital Thread and the Digital Twin have become familiar buzzwords in manufacturing, but many such terms barely make sense to IT experts, let alone AM professionals. In the crowded and jargon-heavy landscape of solutions for digitalisation, articulating future AM software trends can help offer clarity and confidence in IT investments and give insight into the data-driven future of manufacturing, believes Authentise’s Andre Wegner, who shares his vision of the route to developing an effective digital factory with Metal AM’s Emily-Jo Hopson.

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 [First published in Metal AM Vol. 5 No. 1, Spring 2019] ...

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 [First published in Metal AM Vol. 5 No. 1, Spring 2019] ...

Simple and standardised X-ray CT testing in metal Additive Manufacturing

X-ray Computed Tomography (CT), also widely known as MicroCT, is a proven method for not only checking the structural integrity of additively manufactured (AM) parts – for example for unwanted porosity – but also for checking a build’s dimensional accuracy. The main advantage of the technique is of course the non-destructive nature of the assessment; however, there are also many misunderstandings about the capabilities and complexity of the technology. Prof Anton du Plessis and Dr Jess M Waller review the application of CT testing in relation to metal AM and highlight the advantages of a move towards standardised test methods [First published in Metal AM Vol. 4 No. 4, Winter 2018] ...

Siemens: 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. Today, it is supporting the global industrialisation of the technology through its Siemens NX Additive Manufacturing software. In the following report the company’s Aaron Frankel and Ashley Eckhoff explain their belief that, whilst the potential of AM is massive, digitalisation will play a critical role in enabling its transition from a prototyping tool to a serial production technology [First published in Metal AM Vol. 4 No. 3, Autumn 2018] ...

EOS: Developing metal Additive Manufacturing for a truly digital factory

In July 2018, Metal Additive Manufacturing magazine’s Emily-Jo Hopson attended the company’s exclusive EOS Technology Days for an advance preview of its new metal Additive Manufacturing system, the EOS M 300, and a look at its vision for AM and the technology’s place in the digital factory of the future. Held at the company’s attractive rural headquarters in Krailling, Germany, the event offered attendees insight into areas that are key to EOS’s current development strategy [First published in Metal AM Vol. 4 No. 3, Autumn 2018] ...
