The Cygnus NG-20 spacecraft, currently docked with the International Space Station, is carrying an experimental 3D metal printer developed by Airbus for the European Space Agency. This printer, capable of melting stainless-steel wire to create objects, aims to address the technical challenges of metal 3D printing in space and could provide astronauts with resilience and self-sustainment capabilities on future space missions. The printer will test its performance in microgravity conditions by printing four shapes, which will be compared to reference prints created on Earth to understand how the space environment affects the printing process. This technology could potentially enable astronauts to repair or augment space structures on otherworldly settlements like the Moon or Mars, reducing the need for costly shipments of spare parts from Earth.
FiloBot, a plant-inspired robot developed by Emanuela Del Dottore and her team, mimics the growth patterns of climbing vines by utilizing plant behaviors such as phototropism and gravitropism.

Aerojet Rocketdyne and United Launch Alliance (ULA) celebrated the 60th anniversary of the RL10 rocket engine, which became the first engine powered by a combination of liquid hydrogen and liquid oxygen to be fired in space. Since its debut in 1963, 522 RL10 engines have flown in space, primarily on ULA's Delta and Atlas rockets. The RL10 engine has enabled the launch of spacecraft to various destinations in the solar system and is currently being upgraded with additive manufacturing techniques for increased performance and cost savings. ULA plans to debut the RL10C-X engine on its forthcoming Vulcan rocket in 2025.
Rocket engine startup Ursa Major plans to disrupt the solid rocket motors market by utilizing additive manufacturing techniques, commonly known as 3D printing. The company aims to address the broken supply chain and outdated processes in the industry, which have been exposed by the conflict in Ukraine. Ursa Major intends to develop motors ranging from 2 to 22.5 inches in diameter and has already tested a six-inch pathfinder prototype. The company has an undisclosed U.S. government customer and aims to supply motors to the Department of Defense while partnering with other manufacturers. Ursa Major is one of several startups attempting to enter the solid rocket motors business, challenging the dominance of incumbents like Northrop Grumman and Aerojet Rocketdyne.
The US Navy is turning to additive manufacturing, or 3D printing, to address manufacturing challenges and meet the demand for new submarines. With the goal of building one Columbia-class ballistic missile submarine and two Virginia-class attack submarines every year for the next decade, the Navy is commissioning activities to mature metal additive manufacturing. The Additive Manufacturing Center of Excellence in Danville, Virginia, is at the heart of this effort, seeking to expand the supply chain for submarine parts by helping companies adopt metal 3D printing. The Navy aims to print metal parts as standard components for installation on new-construction submarines, increasing capacity, improving quality, and reducing production time. However, there are still technical challenges and the need to qualify and certify the technology for critical parts. The Navy is working on creating a network of printing partners and a digital order book to manage the workload, but industry participation and workforce development are also crucial for success.
NASA has successfully built and tested a 3D printed rocket engine nozzle made of aluminum, which is lighter than conventional nozzles and has the potential to enable deep space flights with increased payload capacity.
