Arcam Q20

GKN Aerospace and additive manufacturing specialist Arcam have partnered to develop a new additive process for the aerospace market.

Called electron beam melting (EBM), the additive process will allow creating metal components using a metal powder that is melted by an electron beam.

EBM is claimed to produce complex, small to medium-sized components with little finishing.

As part of the joint technology development agreement, GKN Aerospace placed an order for two ARCAM Q20 EBM machines, which will be installed at the company’s additive manufacturing (AM) centre in Bristol, UK.

The partnership with Arcam is part of GKN’s AM research and development initiative.

"Called electron beam melting (EBM), the additive process will allow creating metal components using a metal powder that is melted by an electron beam."

The partners plan to create next-generation EBM equipment to produce titanium structures at high volumes.

GKN Aerospace engineering and technology senior vice-president Russ Dunn said: "Our aim has been to fully understand how EBM can be applied to our future aerostructures and aero engines portfolio.

"Through this new strategic partnership with ARCAM, our combined additive manufacturing teams will now take the next steps towards fully industrialising this AM technology."

GKN Aerospace business operates four AM development centres in North America and Europe that focus on specific additive processes and technologies.

Mr Dunn said: "Drawing on GKN Powder Metallurgy’s experience and our own extensive aerospace expertise we aim to develop a roadmap that will industrialise additive manufacturing for this sector."

Additive processes are said to play a key role in facilitating the future aerospace sector’s manufacture at greater speeds and consistency to meet demand for efficient aircraft.

These processes will transform manufacturing across various industrial sectors particularly in aerospace where cost, weight and performance are key components, GKN Aerospace said.
