Lunar Resources, an American pioneering space industrial company proposes to NASA the maturation of the Pulsed Electrical Discharge Additive Manufacturing Lunar Surface Construction system (PE3D-LSC). A novel additive manufacturing system optimized for lunar regolith and the lunar environment. The technology does not use binders or reagents to additively manufacture unadulterated regolith and is highly power efficient. During the Phase I effort, the technology was shown to successfully melt lunar regolith in air and vacuum with a quarter of the power required by state-of-the-art laser systems. In addition, a unique regolith feed system was also successfully tested to be able to feed the PE3D-LSC with regolith without mechanical mechanisms. During the Phase II effort, the PE3D-LSC will be advanced, with a focus on reducing power input and increasing quality of regolith additive manufacturing parts/structured in vacuum to enable the additive manufacture of lunar structures from regolith in geometries and complexity not before possible on the Moon. Anticipated
Benefits: The PE3D-LSC will support NASA and private sector goals of producing in-situ infrastructure on the lunar surface. Key applications include the additive manufacturing of lunar regolith to produce vertical and horizontal structures (landing pads, unpressurized facilities, roads, habitats, pressurized facilities), in-situ photovoltaic substrates, structural elements, concave or parabolic functional structures, radiation shields, and other structures on the Moon. The PE3D-LSC will support the private sector in constructing and maintaining lunar surface infrastructures such as landing pads, roads, and buildings. It can also be utilized to produce structural elements which can be launched off the Moon and assembled in Cislunar. And the technology can perform additive manufacturing of new high-temperature materials on Earth.
