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.

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] ...

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.

Developing an effective metal powder specification for Binder Jet Additive Manufacturing

Powder specifications vary significantly across the various metal Additive Manufacturing technologies. As Andrew Klein, Director of R&D at The ExOne Company, and Jamie Clayton, Operations Director at Freeman Technology explain, powders for binder jetting in particular have very specific process-related requirements. In the following article, the two offer their insight into the rapid assessment and qualification process for a new 316L stainless steel powder.

Rapid qualification of new alloys for Additive Manufacturing through a holistic process chain

The limited number of alloys currently commercially available for metal Additive Manufacturing is regarded as a key factor hindering the growth of the industry. In this article, Rosswag GmbH’s Daniel Beckers reports on a high-speed qualification process that the company has developed for new alloys, and that spans the complete AM process chain – from alloy atomisation to L-PBF process parameters, heat-treatment and mechanical testing [First published in Metal AM Vol. 5 No. 2, Summer 2019] ...

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] ...
