Planning, preparing and producing: Walking the tightrope between additive and subtractive manufacturing

In the following article Delcam’s Kelvin Hamilton explores the current possibilities for design, topology optimisation, simulation, process planning and process preparation in metal Additive Manufacturing (AM). Exploring the three Ps, Plan, Prepare and Produce, all the processes involved in transforming three airbrake bracket designs into final products are revealed. As well as explaining how important it is to appreciate and plan for the significant amount of subtractive manufacturing in metal AM, a number of the lessons learnt in this project are discussed as the author reflects on the experience of planning, preparing and producing parts [First published in Metal AM Vol. 2 No. 1, Spring 2016] ...

Titanium powder pyrophoricity, passivation and handling for safe production and processing

As Additive Manufacturing moves out of the prototyping space and into production facilities with multiple machines, the importance of handling and processing powders, particularly titanium, becomes ever more relevant. In this article Dr Andrew Heidloff and Dr Joel Rieken, from Praxair Surface Technologies, Inc., review best practice when handling and storing titanium powders for AM. Titanium powder can be safely produced, processed, stored and shipped using appropriate precautions, however under certain conditions it can become quite hazardous. These hazards can be mitigated by following the suggested precautions reviewed below [First published in Metal AM Vol. 2 No. 1, Spring 2016] ... Read more »

Process and quality control for AM: Sigma Labs PrintRite3D® methodology for overall quality assurance

Despite the outstanding promise of metal Additive Manufacturing technologies, inconsistent quality, process reliability and speed are currently holding back industry growth and impacting on the cost-effectiveness of new applications. In the following article Sigma Labs’ Dr Vivek R Dave and Mark J Cola review the technical challenges that are faced in enabling metal AM to reach its full potential and the systems that are currently available to address a number of critical issues [First published in Metal AM Vol. 2 No. 1, Spring 2016] ...

Metal AM in Finland: VTT optimises industrial valve block for Additive Manufacturing

VTT, based in Espoo, Finland, is one of Europe’s largest research and technology centres with a long track record in metal powder processing technologies. In the following case study VTT’s Erin Komi reviews the development of an additively manufactured valve block for demanding industrial applications. The project, in conjunction with industrial partner Nurmi Cylinders, looked at the optimisation of the valve block in terms of size reduction, weight saving and performance gains [First published in Metal AM Vol. 2 No. 1, Spring 2016] ...

Formnext 2015: Product launches take centre stage at Europe’s new exhibition on Additive Manufacturing

The much anticipated inaugural formnext exhibition took place in Frankfurt from November 17-20, 2015. Squarely aimed at an industrial audience, the event succeeded in attracting almost all the major metal Additive Manufacturing technology suppliers. Whilst taglined as the international exhibition on additive technologies and tool making, there was a real sense that it was the Additive Manufacturing community that most fully embraced this new exhibition concept. As Metal AM magazine’s Nick Williams reports, AM technology suppliers took the opportunity to make a number of new product launches and announcements [First published in Metal AM Vol. 1 No. 4, Winter 2015] ...

Hot Isostatic Pressing: Improving quality and performance in AM parts production

Hot Isostatic Pressing (HIP) has been used for a number of decades as a method to consolidate metal powders and metal matrix composites to produce fully dense components, to eliminate porosity in sintered parts, to produce metal clad parts through diffusion bonding, and to eliminate defects in castings. HIP is now also playing an important role in assuring and increasing the quality of critical components produced by powder-based Additive Manufacturing. In the following article Magnus Ahlfors and Johan Hjärne describe the HIP process and its influence on the microstructure and properties of AM Ti-6Al-4V alloys [First published in Metal AM Vol. 1 No. 4, Winter 2015] ...

The current status and outlook for metal Additive Manufacturing in Japan

Despite playing a significant role in the early development of Additive Manufacturing technologies, there is a belief in Japan that the country’s industry has fallen behind in the wider adoption of metal Additive Manufacturing. In this report for Metal AM magazine Professor Hideki Kyogoku, of Kinki University, and a project leader of the country’s Technology Research Association for Future Additive Manufacturing (TRAFAM), reviews the history of the technology in Japan and its current status. He also presents the work being undertaken by TRAFAM on the development of the next generation of metal AM systems and materials [First published in Metal AM Vol. 1 No. 3, Autumn 2015] ...

A story of failure and success in metal AM: The reality of developing a titanium bike part

Metal Additive Manufacturing promises to enable smaller organisations to compete with global corporations in the development of new products. Expensive tooling and traditional production lines, it is suggested, need no longer be a barrier to market. As US-based designer and engineer Spencer Wright reveals in this insightful report, the reality of developing a low volume AM titanium part for production exposes a number of challenges that the industry needs to overcome if it is truly able to serve a new generation of product developers [First published in Metal AM Vol. 1 No. 3, Autumn 2015] ...

Developments in the Additive Manufacturing of titanium at PM Titanium 2015

The PM Titanium 2015 conference, held in Lüneburg, Germany, from August 31 to September 3, 2015, was the latest in the series of international conferences specifically focused on the processing, consolidation and metallurgy of titanium. As Dr David Whittaker reports for Metal Additive Manufacturing magazine, the ambition to apply titanium AM components in critical applications continues to drive researchers to further understand the influences of processing parameters on achieved microstructure and on the relationships between microstructure and mechanical properties [First published in Metal AM Vol. 1 No. 3, Autumn 2015] ...
