LPW Technology: AM materials specialist expands into metal powder production

LPW Technology, a provider of ultra-clean metal powders for Additive Manufacturing, recently celebrated the official opening of its new purpose-built metal powder manufacturing facility in Widnes, Cheshire, UK. The result of a £20 million investment, the company expects that this new plant will be capable of producing around 1,000 tonnes of gas atomised alloy powders per annum, with complete digital integration of manufacturing control processes. Bernard Williams, Consulting Editor at Metal AM magazine, reports on his visit to the official opening of the 9,700 m2 plant and tour of the new facility.

An introduction to metal powders for AM: Manufacturing processes and properties

As the AM industry grows, so does the number of metal powder suppliers and the range of different powder types that are available. In the following article Toby Tingskog presents a beginners’ guide to understanding metal powders for AM. Topics include powder manufacturing processes, spherocity, chemistry and measurement technologies, as well as considerations in relation to heats, lots and batches. As such, it is hoped that this review will allow for a clearer understanding of powder properties and reduce confusion among end users [First published in Metal AM Vol. 4 No. 2, Summer 2018] ...

Digital Metal: High-precision Additive Manufacturing technology from a metal powder giant

Sweden’s Digital Metal® has enjoyed a significant increase in its profile over the last year. This was achieved, in part, by a major brand relaunch, but more significant was the move to begin selling its machines to third parties, rather than offering AM component manufacturing solely in-house. Metal AM magazine’s Emily-Jo Hopson reports on the evolution of the company, its unique approach to developing its technology and the benefits of being owned by the world’s largest producer of metal powders [First published in Metal AM Vol. 4 No. 1, Spring 2018] ...

The challenges of metal powder removal: Managing risk, productivity and quality

One of the goals for the metal Additive Manufacturing industry is the automated series production of components through a streamlined manufacturing process. Such an ambitious goal faces a major obstacle: the challenge of powder removal. Joseph Kowen reviews some of the significant risks facing AM producers at this stage of the process, from health and safety considerations to the impact on quality and productivity, and highlights some of the technologies being developed to address them [First published in Metal AM Vol. 4 No. 1, Spring 2018] ...

Oerlikon: Swiss industrial group positions itself as a leading developer of AM components and materials

Over a period of just twelve months, Switzerland’s Oerlikon Corporation AG has made a major move into the world of Additive Manufacturing. Through a combination of acquisitions and new facility investments, the company has established itself as a leading international developer of both AM materials and components, offering its customers the complete process chain, from new alloy development to component post-processing and testing. Metal AM magazine’s Nick Williams reviews the company’s progress to-date [First published in Metal AM Vol. 3 No. 4, Winter 2017] ... Read more »

Costs and considerations when investing in a metal Additive Manufacturing system

Making the investment in a metal Additive Manufacturing machine is, for many, the first step on a journey to truly understanding how the technology can transform a business. There are, however, many considerations when planning such an investment; from essential ancillary equipment and devices, such as sieving stations, to facility changes, software and support. In this exclusive report, Terry Wohlers and Olaf Diegel highlight some of the commonly overlooked costs and considerations when making the move to establish an in-house AM capability [First published in Metal AM Vol. 3 No. 4, Winter 2017] ...

Beyond particle size: Exploring the influence of particle shape on metal powder performance

In recent years much effort has been put into developing powders that are optimised for AM processes. As a result, a far greater understanding of the complex requirements for powders now exists. Particle size is widely recognised as a key property, but there is also an appreciation that particle shape has an important role to play. As Malvern Panalytical’s Debbie Huck-Jones and Cathryn Langley, explain, finer particles are advantageous from the perspective of packing behaviour, but are typically associated with poor flowability, compromising processing efficiency. Controlling particle shape can help to alleviate this problem [First published in Metal AM Vol. 3 No. 4, Winter 2017] ... Read more »

POWDERMET2017: Developments in powder production methods for AM

In addition to the parallel Metal Powder Industries Federation’s AMPM2017 conference, the programme for the POWDERMET2017 International Conference on Powder Metallurgy & Particulate Materials, Las Vegas, June 13-16, 2017, included technical sessions on AM. Two of these sessions were devoted to powder production methods for AM feedstocks and this report from Dr David Whittaker reviews three selected papers in this subject category [First published in Metal AM Vol. 3 No. 4, Winter 2017] ...

AMPM2017: Understanding the impact of powder reuse in metal Additive Manufacturing

An issue of significant current interest to the AM world, which can potentially impact both the quality and cost-effectiveness of built parts, is whether there is a limit on the number of times that metal powders can be cycled around an AM process. In this article, Dr David Whittaker reviews three presentations on the topic from AMPM2017, the fourth annual Additive Manufacturing with Powder Metallurgy Conference, held in Las Vegas, USA, June 13-15, 2017 [First published in Metal AM Vol. 3 No. 3, Autumn 2017] ...
