The Shell Hull Reinforcement Module and the Chelonian Hull Reinforcement Module cannot be crafted in either the Experimental or Stable Builds. They both require a Reefback DNA Sample, which requires a Transfuser, which also cannot be crafted, as it is unimplemented as of now. Although the Transfuser can be spawned in, the game will not register if you have taken a DNA sample from a Reefback, thus making it impossible to craft those particular upgrades. As for the normal Hull Reinforcement Module, you must first find the Reinforce Hull Fragment, analyze it using the Fragment Analyzer, and then craft it with a Fabricator either in a Seabase or the Cyclops.
