Remote-controlled robots could one day build giant solar farms in space, according to a recent trial in the UK. British startup Space Solar conducted the test at the UK Atomic Energy Authority’sfacilities on the University of Oxford’s Culham Campus, which hosts several fusion research initiatives. The company used two remotely operated robotic arms to assemble a section of the support structure for its future solar power satellite. The device aims to beam the Sun’s energy from space to Earth.  According to Space Solar, the trial proved that robotics can assemble gigawatt-scale solar power satellites. Sam Adlen, the startup’s co-CEO, said the demonstration opens the door to all manner of in-space infrastructure projects.    “This is a milestone not just for our satellite architecture, but for the future of large-scale structures in space, from data centres to energy infrastructure,” he said. As part of its plans to build a working fusion reactor, UKAEA is developing robots for extreme industrial environments, such as maintaining future fusion power plants. The trial shows that those same machines may also show promise for cosmic applications.  Professor Rob Buckingham, executive director of UKAEA, said building fusion reactors and structures in space shared some common challenges, such as remoteness, radiation, and extreme temperatures. The demo suggests that fusion-hardened robotics could help automate the complex task of assembling vast solar farms in orbit.    A solar revolution in space? Space Solar plans to capture the Sun’s energy in space, using huge satellites equipped with solar arrays that are several kilometres long and around 20 metres wide. The probes would capture the energy via microwaves and wirelessly transmit it to dedicated receiver stations on Earth, which would convert the energy into electricity.    By 2029, Space Solar plans to commission its first 30MW demonstrator system, which would be capable of powering around 1000 homes. By the early 2030s,  the startup plans to deploy its first gigawatt-scale solar space farm. The UK Space Agency has provided grant funding for the development of the startup’s first satellite. Solar panels are theoretically capable of gathering far more energy in space than on Earth because, unhindered by the atmosphere, the intensity of sunlight is much greater. They could also beam energy from orbit 24/7, regardless of the weather on the ground.  However, space-based solar power faces many challenges. It’s currently far more expensive than ground-based solar systems — the initial development of a gigawatt-scale prototype could cost €15bn–€20bn. Then there are the potential environmental impacts. Installing a satellite of that scale could involve hundreds of separate rocket launches, contributing to atmospheric pollution.  Nevertheless, the European Space Agency, NASA, and several startups in the UK, US, China, and Japan are all working to make space-based solar a reality.

UK-based engineering equipment supplier Kingsbury and metal additive manufacturing company Additure have been appointed by the UK Atomic Energy Authorityto supply additive manufacturing technology and expertise as part of the UK’s ongoing efforts to advance fusion energy research. The partnership will support the development of components designed to endure the extreme conditions within fusion reactors, with a focus on innovative materials and design approaches. A key area of focus involves the use of tungsten—layered with materials such as copper—to achieve the necessary durability. To support this work, Kingsbury and Additure will deliver and install a Nikon SLM Solutions SLM 280 2.0 Laser Powder Bed Fusionsystem at UKAEA’s facilities. “We are excited to support the team at the UKAEA as they scale, not just with the SLM 280’s LPBF capability, but with all the key elements of the AM ecosystem to make this a robust manufacturing solution for UKAEA and the UK’s fusion programme,” said Will Priest, Business Development Manager at Additure.

It operates as an executive non-departmental public body, sponsored by the Department for Energy Security and Net Zero. A key part of its mission involves fostering industrial fusion capability by working with manufacturers and supply chains to introduce and scale the technologies required for commercial fusion energy deployment. “The UKAEA aims to develop the commercialisation of additive manufacturing and support UK industry in the transition into the fusion energy sector. We conduct the complex areas of research and development to the point where it becomes commercially viable, the advice and support of our supply chain is hugely valuable in expediting this process,” said Roy Marshall, Head of Operations for Fabrication, Installation, and Maintenance at UKAEA.

Additure’s Role and Technology Contribution At the center of this initiative is the SLM 280 2.0, an LPBF system designed for high-performance applications, including the development of refractory metals. The system offers build speeds up to 80% faster than single-laser alternatives and includes integrated safety features such as a powder sieve module and system cooling enhancements. Beyond equipment delivery, Additure is also providing comprehensive technical training to UKAEA’s research, materials, and design teams. This includes detailed guidance on machine setup, build optimization, and specialized functions—such as a heated reduced build volume. “The applications training from Additure will provide our engineers with new ways to design some of the complex structures required by fusion and allow them to do this using some of the most challenging materials to work with. For additive manufacture to contribute to fusion energy, more designers need to think, ‘What process is most suitable for the desired thermal or structural performance?’ And ‘how do I create a design that is best optimised for additive manufacture?’”, said Mr. Marshall. Advancing Laser Beam Shaping 3D Printing  Given its notable advantages for industrial metal 3D printing, beam shaping capabilities are being developed and commercialized by several players in the research and LPBF 3D printing spheres. In 2024, German research organization Fraunhofer Institute for Laser Technology ILT showcased its new 3D printing beam shaping technology. Working with the Chair of Technology of Optical Systemsat RWTH Aachen University, the new platform, the Fraunhofer team is developing a test system for investigating complex laser beam profiles.  This platform can create customized beam profiles for laser powder bed fusion3D printing, enhancing part quality, process stability and productivity, while minimizing material waste.  In 2022, Equispheres and Aconity3D used laser beam-shaping 3D printing to achieve build rates nearly nine times higher than industry norms. Equispheres’ NExP-1 aluminum powder was used with Aconity3D’s AconityMIDI+ LPBF 3D printer to unlock speeds exceeding 430 cm3/hr for a single laser.  The system was modified to employ a PG YLR 3000/1000-AM laser with beam-shaping capabilities. By using a shaped beam over a zoomed Gaussian profile, the team reduced overheating and mitigated spatter formation during high-speed 3D printing.  Take the 3DPIReader Survey — shape the future of AM reporting in under 5 minutes.
