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

UV resin printed plastic instead might work.

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:
