EBAM satellite fuel tank domes 'largest additively manufactured parts in space'. Sciaky, Inc., Chicago, Illinois, USA, a subsidiary of Phillips Service...
Satellite fuel tanks must be both strong and lightweight to withstand the rigors of launch and decade-long missions in the vacuum of space, with even very small flaws or leaks catastrophic for the satellite’s operations.

Hospital reconstructs patient’s chest using titanium 3D printed implant
According to NHS Wales, the 71-year-old patient required the implant following surgery to remove an extensive sarcoma – a cancer growth in the soft tissue – from his chest, resulting in the removal of part of the breastbone and three ribs altogether. Though necessary, the surgery left the patient at risk of chest wall destabilisation and potential collapse.
Traditionally, the chest would have been reconstructed using a cement prosthesis. However, although hard-wearing, cement prosthetics do not provide an exact fit and can move within the body, causing issues such as dislocation. In addition, cement prosthetics take around an hour and a half to prepare during surgery, putting the patient at increased risk of complications on the operating table.
Using metal 3D printing, the surgical team was able to produce a titanium implant to the patient’s exact fit and specifications, as well as reducing the overall surgery time by around two hours. To achieve a custom fit, the implant was designed by Heather Goodrum, Morriston’s Biomedical 3D Technician, and Peter Llewelyn Evans, Morriston’s Laboratory Services Manager, based on CT scans of the patient’s chest.

Proslab, a dental laboratory based in Canterbury, Victoria, Australia, states that it has fully digitalised the manufacture of its cobalt chrome removable partial dentures (RPDs) using metal Additive Manufacturing from the UK’s Renishaw plc. The company has now installed what is thought to be the first metal AM system for dental applications in Australia.
Bugatti has 3D printed a titanium brake caliper
“It was a very moving moment for the team when we held our first titanium brake caliper from the 3D printer in our hands. Everyone who looks at the part is surprised at how light it is – despite its large size. Technically, this is an extremely impressive brake caliper, and it also looks great.”

NASA completes hot-fire testing of RS-25 rocket engine with metal 3D printed component
NASA and Aerojet Rocketdyne have completed hot-fire testing of an RS-25 rocket engine containing its largest metal additively manufactured component to date.
During a 400-second test at Stennis Space Center, Mississippi, USA, Aerojet Rocketdyne was able to evaluate the performance of its metal additively manufactured vibration damping device, known as a ‘pogo accumulator assembly’. It is hoped that the use of AM to produce aerospace components will help to lower the cost of future missions for NASA’s Space Launch System (SLS) heavy-lift rocket.
The pogo accumulator assembly is a complex piece of hardware consisting of two components – the pogo accumulator and pogo-z baffle – and acts as a shock absorber to dampen oscillations caused by propellants as they flow between the vehicle and the engine. The pogo accumulator assembly is important to ensuring a safe flight by stabilising these potential oscillations.

The first metal additively manufactured / 3D printed spare parts have been produced at Mercedes-Benz Trucks, marking a major step toward on-demand parts for older & classic vehicle models worldwide...
In the past, the production of metal replacement parts has been dependent on the availability of the type of tool used in their original manufacture, making the cost of obtaining replacement parts for older models prohibitively high, especially in small batches. The use of AM has the potential to allow the geometry of parts to be input and reproduced using the same universal platform, making their production cost-efficient even at low quantities.
