Established and widely accessible
Resin 3D printing. Allows for rather small high detail parts compared to
FFF/FDM molten plastic extrusion printing.
Either used directly or for mold making.
Experimental - How to make very many small precise decently hard metal parts for extremely cheap?
(wiki-TODO: Add images.)
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:
Dense galvanic deposition of significant layer thicknesses (by Shaun Mulligan):

Could this work or would?
UV resin for small scale positive =>
metakaolin for heat tolerant geo-polymer negative =>
aluminum (or brass) powder for positive (in case of aluminum N2 or Ar atmosphere while melting the powder)
Potential issues: Geopolymer mold deforming at temperature, aurface wetting and tension issues like
aluminum fusing with silicatic geopolymer moldor (less likely) aluminum not filling the edger
(Idea here: Unlike calcium based cement geopolymer can be water free and thus serve as mold for higher temperatures without cracking.)
