I added lapping machine as a dependency, but there are also other ways to remove the core and prepreg from a PCB.

@rahix does it make sense to add weak dependencies to the tech tree or is this overkill?

Please see https://git.fa-fo.de/fafo/techtree#modelling-approach for a description on how we handle such "multiple approaches" choices.
