The printing process starts with a thin layer of sand. The printer then sprays the sand with magnesium-based glue from hundreds of nozzles, which binds the sand into rock. That rock is then built up layer by layer, eventually taking shape of whatever object it is destined to become, be it a curvy sculpture or an entire cathedral. Dini has even been talking with La Scuola Normale Superiore, Alta Space and Norman Foster to design a printer that would work with moon dust, essentially creating a machine that can make an almost-instant moonbase!

Cool story, but this whole "printing" metaphor has been stretched too far. Just because these machines have a superficial similarity to ink jet printers, doesn't make them "printers".
These are computer controlled material sprayers that work in 3 dimensions. They don't "print" anything - they spit out liquid materials that soon solidify for the purpose of constructing objects in layers.
These have about as much in common with an ink jet printer as they do cement trucks.
