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]

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]

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]

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]

With such intense levels of interest in Additive Manufacturing, the pressure for businesses to adopt the technology can be high. Expectations, however, need to be managed and the business opportunities and challenges need to be understood. As Onno Ponfoort and Chris Krampitz explain, the dilemmas for any company looking to move into this arena range from fully understanding the advantages that the technology presents to ensuring that those tasked with the project, as well as potential customers, have the necessary technical training [First published in Metal AM Vol. 1 No. 3, Autumn 2015]

The consistency of metal powder particle size, shape and flow is essential for those companies looking to move to serial production of high quality components. The correct characterisation of powders enables the necessary quality control to ensure powder behaviour is predictable and repeatable from batch to batch. Dr Paul Kippax, Product Group Manager, Malvern Instruments, and Dr Robert Deffley, Research & Development Manager, LPW Technology, report on the process undertaken at LPW to ensure its powders meet customer expectations [First published in Metal AM Vol. 1 No. 3, Autumn 2015]
