A researcher from the College of Glasgow’s James Watt College of Engineering has been named because the inventor on a brand new patent that, he says, might ship efficient 3D printing to be used in space-based factories — examined on a infamous “Vomit Comet” journey hosted by the European Area Company (ESA).
“Presently, all the things that goes into Earth’s orbit is constructed on the floor and despatched into area on rockets,” Giles Bailet, the named inventor, explains. “They’ve tightly restricted mass and volumes and may shake themselves to items throughout launch when mechanical constraints are breached, destroying costly cargo within the course of. If as an alternative we might place fabricators in area to construct buildings on demand, we’d be free of these payload restrictions. In flip, that might pave the best way to creating way more bold, much less resource-intensive tasks, with methods truly optimized for his or her mission and never for the constraints of rocket launches.”
“Additive manufacturing, or 3D printing, is able to producing remarkably advanced supplies shortly and at low price. Placing that expertise in area and printing what we’d like for meeting in orbit could be fantastically helpful,” Bailet continues. ““Nonetheless, what works properly right here on Earth is commonly much less sturdy within the vacuum of area, and 3D printing has by no means been finished outdoors of the pressurised modules of the Worldwide Area Station. The filaments in typical 3D printers usually break or jam in microgravity and in vacuum, which is an issue that must be solved earlier than they are often reliably utilized in area.”
Bailet’s patent describes a brand new design of 3D printer tailored particularly to be used in microgravity, swapping the strings of filament discovered on conventional printers for grains of fabric fed from a tank to a nozzle utilizing the patented “granular materials conveyance and switch equipment.” The result’s a printer that ought to have the ability to not solely function in orbit aboard area stations, confirmed by assessments on a parabolic plane colloquially referred to as “Vomit Comets,” which simulate microgravity, however even straight within the vacuum of area itself.
“We have examined the expertise extensively within the lab and now in microgravity, and we’re assured that it’s able to carry out as anticipated, opening up the potential of 3D printing antenna and different spacecraft components in area,” Bailet claims. “3D-printed area reflectors, like these being developed by my colleague Professor Colin McInnes’ SOLSPACE mission, might collect vitality from the solar 24 hours a day, serving to us attain net-zero with a wholly new type of low-carbon energy era.”

“Equally,” Bailet continues, “crystals grown in area are sometimes bigger and extra well-ordered than these made on Earth, so orbital chemical factories might produce new or improved medicine for supply again to the floor. It has been advised, for instance, that insulin grown in area could possibly be 9 occasions more practical, permitting diabetic individuals to inject it as soon as each three days as an alternative of thrice a day, as they usually need to do right now.”
The patent has been granted by the Phrase Mental Property Group beneath Worldwide Patent Quantity WO 2024/105126 A1; Bailet and colleagues at the moment are looking for funding so as to exhibit the expertise in area.
