regolith pillar
a mixture of sand & resin to simulate extraterrestrial soil
How will we build on the surface of other planets?
Regolith pillar was created by 3D printing a lightweight mold using polyvinyl alcohol (PVA) filament, and filling it with a mixture of sand & resin. The PVA, being water soluble, was melted away after being placed in a basin of water for 76 hours. After melting it away, one can see the beauty and innate strength of the sand once it has solidified.
