HKUST scientists unveil yeast-gelatin material for 3D-printing Mars houses

Test domes show concrete-comparable strength

Reporting details the process: the sand-gelatin-yeast mixture is extruded through a nozzle into cold, near-vacuum conditions where it freeze-dries into a porous foam; current test domes are only 45 mm tall but reach 10–12 megapascals of compressive strength, comparable to low-grade concrete.

“So far the test domes are only 45 mm tall, but the material reaches 10 to 12 megapascals in compressive strength, comparable to low-grade concrete.”
