How to Make Building Blocks for a Lunar Habitat

The challenge of building habitats on the Moon is considerable, mainly because most additive manufacturing (aka. 3-D printing) techniques are not feasible. By utilizing a 3-D printing method known as light-based sintering, future missions to the Moon could manufacture bricks out of lunar regolith, rather than trying to build whole structures. This would facilitate a long-term human presence on the lunar surface, consistent with the Artemis Program and other plans for lunar exploration and development.
