OVERLAPS: Bellows, wiring, insulative materials. Fiberglass tape etc. Permeability of plastics, VOC's.  Drying/Vacuum/Annealing, Psychrometry/humidity measurement, etc. Properties of materials, especially Alloys, have a lot of overlap. Resins/Filaments/etc. Design for obv reasons overlaps a lot with the others e.g. Slicers, etc. Loctite overlaps bcz applicable to many areas Same for glues/pastes (for silicone heater, or sensors, potting, etc.) Fans for chamber control, part cooling, etc. also technically slicer related..... etc. etc.
