A stalactite/stalagmite forms from water droplets and
the
dissolved solids therein.
The idea here is to create a dripping system (with
perhaps
faster accreting chemicals than those naturally found in
caves) that would, from a 3D design (e.g. a Venus of
Milo, or a
David, or an arbitrary
shape), create the necessary set of
water sprouts and dissolved solids to create the design
over a
period of time, ideally faster than geological, so that
results could be
observed.

You just need higher ambient temperatures, although the flowstone produced may not be as smooth and dense as the naturally produced item. |

So technically I was right, it 'Is' a Transformer... |

One of the Dinobots, surely? |

Perhaps a very slow 3D printer, consisting of a nozzle that moves
under computer control in the horizontal plane, and every now and
again drips a drop of calcium-bearing water onto the baseplate
beneath? |

[+] Maybe do this with ice. Forming an actual rock
formation would be more impressive, but an ice sculpture
might be possible in hours or days. |

And I thought this would be some device for escaping from German prisoner of war camps. But, 1 bun. |

The thing is that it would continue growing after it was "finished" |
|
| |
Could some flow modelling system be used so that it grew and then blocked its own delivery rills? |
|

How would the undercuts be formed of a complex structure
like a human figure? A pyramid type mound of various
coloured strata would be easy but I can't see how anything
else could be generated simply by the stalagtite process,
but the author I'm sure can explain. |

Well, perhaps we can implement fans as well to add erosion?
I suppose template forms would be cheating. Well, I'm sure
Trump will come up with something. |

The warmth of his cheery, radiant smile will certainly evaporate the water faster. Keep the Democrats away - cold and slime won't help your sculpture to grow. |

Cycles of different media with the final wash away cycles. -98°C methanol support for ice?
A drippy Venus of Milo might be interesting. |
