[https://en.wikipedia.org/wiki/Lost-wax_casting Lost-wax casting] - No wax on Mars obviously....

[https://en.wikipedia.org/wiki/Matrix_molding Matrix molding] - First create the rigid outer shell, then introduce the softer and more fluid molding material. Used for complex shapes using composites such as with glass and glass/ceramic composites.

[https://en.wikipedia.org/wiki/Vacuum_forming Vacuum forming] - Could just open a valve to the atmosphere. Need some positive pressure though (oxygen would be a waste). Maybe just compress the atmosphere? Not much atmosphere to compress... How much pressure difference would be needed for vacuum molding. Need the rubber/plastic sheet too...

[https://en.wikipedia.org/wiki/Transfer_molding Transfer molding] - Squeeze viscus fluid into holes.

And of course 3d printing.
