Experimental
Galvanic electroforming/electrotyping:
First crude experiment. FDM printed plastic was not tight enough.

UV resin printed plastic instead might work.
CG model of a mold:

The risk of too fast growth is worst case dendridic growth with porosity
or still bad large single crystals brittle as the grain boundaries.
Thus relevance of the following:
