Victoria M. Miller bends glass with a laser from several inches away, no molds, no machinery, no contact—and the material simply folds into a new shape. At the University of Florida's Herbert Wertheim College of Engineering, this isn't sleight of hand. It's laser forming, a manufacturing process that could transform how astronauts build on the moon.
The technology matters because space travel lives by a brutal constraint: every pound costs a fortune to launch. Conventional manufacturing requires heavy machinery, tooling systems, and massive workshops—luxuries that make no sense when you're trying to send supplies beyond Earth's gravity well. Laser forming sidesteps all of that. By using concentrated heat to reshape materials without physical contact, the process requires minimal equipment and maximum flexibility. The team, led by Miller in the Department of Materials Science and Engineering, recently completed a research phase examining how different atmospheric conditions affect laser bending—a critical question when you're planning to manufacture in the vacuum of space.
Their latest findings, published in Lasers in Manufacturing and Materials Processing, reveal something even more promising: the process works on nearly any material. "I haven't found a material that we can't bend yet, even glass," Miller said. One experiment particularly captured the team's imagination. They asked a collaborator to create glass from lunar regolith—the loose rock and dust scattered across the moon's surface. Then they used their laser forming technology to bend it. The result was a proof of concept with profound implications: you could manufacture structures directly from materials already on the moon, eliminating the need to launch building supplies from Earth at all.
The practical applications for astronauts are immediate and tangible. When a tool breaks in space, carrying three spare parts of everything aboard a spacecraft is impractical. "When something breaks in space, you don't want to have to carry, you know, three spares of every part," Miller explained. "It would be really convenient if you could just make a spare part on demand." The same technology could allow astronauts to manufacture replacement parts in orbit or on lunar bases, transforming missions from logistical nightmares into self-sufficient operations.
Beyond the moon, laser forming promises flexible manufacturing on Earth too. The Department of Defense has taken interest in the technology's potential for flexible, lightweight production systems. Miller noted that the same physics that works in the vacuum of space can serve terrestrial applications in ways that traditional manufacturing cannot. The research reflects a broader shift at the University of Florida toward collaborative, future-focused space exploration—not just asking what's possible, but how to keep astronauts safe and healthy while they build humanity's outposts among the stars.
For now, the moon awaits. As the research continues and the technology matures, lunar glass bent by invisible beams of light might one day become the foundation of shelters, tools, and structures that humans build not on Earth, but on worlds beyond.
