including telecommunications, science and robotics. In space applications, there are a number of disadvantages to using a liquid or greasebased lubricant, such as low temperature viscosity, evaporation, loss of lubricant and contamination of other parts of the spacecraft. To address these issues, two concept designs were developed using Croft’s Realiser SLM-250 machine. These were both focused on managing the lubricant within the bearing system more effectively, with a particular emphasis on the challenges of the space environment.
instance, it was deemed more valuable to develop the lubricant retaining cage further.’ ‘We learnt a number of valuable lessons during this study, the most important of which was in the design process – while AM technology can give greater design freedom relative to conventional machining, it is not without constraints,’ added Grant Munro, project manager at ESR Space.’ In terms of next steps, a roadmap has been created to show timescales for exploitation within the space industry and beyond.’ While it is likely that the component developed will be initially used for spacecraft applications alone, the use of the technology in other industries such as nuclear, aerospace and medical will be explored in parallel.

Valuable lessons ‘It is always advised to have several options when seeking to identify a bespoke solution using innovative technologies,’ said Neil Burns, director at Croft Additive Manufacturing. ‘Following the creation and analysis of the two prototypes in this
Croft is researching the use of additive manufacturing (AM) to develop bespoke spacecraft mechanisms.
Object 3D printed from asteroid metal Planetary Resources and 3D Systems have 3D printed a logo using material from a pulverized, powdered and processed asteroid. The object was shown at the Consumer Electronics Show (CES) in Las Vegas, USA. It was printed with 3D Systems’ ProX DMP 320 metals 3D printer and is reportedly the first part ever 3D Printed with material from outer space and is reminiscent

The asteroid (or meteorite) used for the print materials was sourced from the Campo Del Cielo impact near Argentina, and is composed of iron, nickel and cobalt – similar materials to refinery grade steel.

Arcam focuses on the US Arcam reports that its CEO, Magnus Rene´, will temporarily move to the US to lead the Arcam Group from the office in Woburn, MA, in order to focus on the US market. Woburn is conveniently located with regards to Arcam’s subsidiaries AP&C in Montreal and DiSanto in Shelton, CT, as well as to investors on the EAST COAST. ¨ lndal, Arcam’s formal HQ will remain in Mo Sweden. ‘The reason for my relocation is that I will focus more on the US market where
options, growth potentials and strategic opportunities are huge,’ says Magnus Rene´, CEO and President of Arcam. ‘There are several major players in the aerospace and orthopedics industries on the US East Coast. I also want to work closer to our subsidiaries in Shelton and Montreal to develop our businesses for EBM, powders and contract manufacturing.’
