Managing the industrialisation process: Notes from Euro PM’s seminar on the future of Additive Manufacturing

During the Euro PM2019 Congress and Exhibition in Maastricht, the Netherlands, this October, a number of Special Interest Seminars were held focusing on various aspects of the Powder Metallurgy and Additive Manufacturing industries. In one seminar, Dr Uemit Aydin, GKN Additive, and Nicholas Turner, Materials Solutions, looked to the future of Additive Manufacturing and expressed their views on its industrialisation. David Whittaker attended the SIS on behalf of Metal AM magazine and reports on its conclusions.[First published in Metal AM Vol. 5 No. 4, Winter 2019] ... Read more »

Binder Jetting and beyond: Optimising the use of metal powders for Additive Manufacturing

The high cost of metal powders for Additive Manufacturing makes them a primary focus for cost management. Learning how to treat and store such powders in order to maintain and optimise their performance and value is one way to improve production economics. Here, Dr Rajeev Dattani, from Freeman Technology, UK, and Dr Animesh Bose, Desktop Metal, USA, review how to test powders in order to develop this knowledge, and examine treatment and storage regimes that can be beneficial.

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.

From silicone and rubber to steel and ceramic: the weird and wonderful world of wipers

In powder bed Additive Manufacturing processes, the recoater system is responsible for spreading a fine and even layer of powder for each layer of a build. This system typically uses wipers to create the necessary surface, with the variants of wipers used being almost as diverse as the number of AM machines on the market. Olaf Diegel and Terry Wohlers explain why it is not only machine operators, but also designers and engineers, who need to be aware of the weird and wonderful world of wipers.

Thinking about metal Binder Jetting or FFF? Here is (almost) everything you need to know about sintering

With the arrival of high-volume metal Binder Jet systems and a growing interest in metal Fused Filament Fabrication, the AM industry is set for a new phase of growth. The ability to use this new generation of systems for the production of ‘green’ parts is, however, only half of the story. The sintering of these parts to create large quantities of finished product to a consistent quality requires both an investment in furnaces that can cost in excess of $1 million each, and a thorough understanding of sintering. In this article, Prof Randall German, the leading authority on the science of sintering, outlines the process and its core challenges. [First published in Metal AM Vol. 5 No. 3, Autumn 2019] ...

Metal Binder Jetting and FFF: Considerations when planning a debinding and sintering facility for volume production

A new generation of Binder Jetting machines now promises to deliver high volumes of parts at previously unimaginable speeds. Metal AM’s Nick Williams interviews Stefan Joens and the team at Elnik Systems LLC, a leading provider of industrial debinding and sintering furnaces, about the reality of entering this field and the technologies and equipment that are needed for the often underestimated processes of debinding and sintering.

Velo3D: How a ‘support-free’ Laser Powder Bed Fusion process could remove roadblocks to serial Additive Manufacturing

With its Sapphire machine and Flow build preparation software capable of highly-controlled, virtually support-free Additive Manufacturing, Velo3D is pushing the limits of what is possible with Laser Powder Bed Fusion (L-PBF). Since launching its first machine in 2018, the California-based company has seen success with a range of highly complex parts which would challenge even the most experienced AM engineer. In this article, Zach Murphree, Velo3D’s Vice President of Technical Partnerships, explains the key factors which set the company’s process apart from the wider AM market.

United Technologies: Pioneering new possibilities for Additive Manufacturing in aerospace

United Technologies Corp (UTC), through its Pratt & Whitney and Collins Aerospace businesses, has a long history of innovation in aerospace engineering. As Venkat Vedula, Executive Director of UTC’s Additive Manufacturing Center of Expertise (AMCoE), and Vijay Jagdale, the centre’s Principal Engineer, explain, this tradition is today being continued through the corporation’s cutting-edge Additive Manufacturing activities. This report highlights, with the support of an in-depth case study, the centre’s core areas of activity and UTC’s vision for the future of AM. ... Read more »

Additive Manufacturing at HP: A new ‘centre of excellence’ supports the move to volume production

On June 12th, HP Inc. formally opened its new 3D Printing and Digital Manufacturing Center of Excellence at its campus in Barcelona, Spain. Metal AM magazine’s Emily-Jo Hopson attended the event and here reports on the 14,000 m2 facility’s opening and the company’s rapid rise in the world of Additive Manufacturing. She reveals how, whilst the company is not traditionally associated with equipment for industrial manufacturing, many of its core technologies directly lend themselves to a new generation of metal binder jetting systems.

Powder removal: The Achilles heel of powder bed-based metal Additive Manufacturing

The broader industrial-scale use of powder bed-based metal Additive Manufacturing is resulting not only in improvements in process performance and material properties, but also in a growing scrutiny of the process by regulators, risk managers and legal departments. One key area of their focus is powder removal, the step in the production chain where there is perhaps the greatest risk to worker and plant safety as a result of dust exposure. Joseph Kowen reviews the current status of this topic and reports on how leading producers are addressing what is often described as the Achilles heel of metal AM [First published in Metal AM Vol. 5 No. 2, Summer 2019] ...
