This one is tricky since we want to have ONE source of truth for temp ratings
No duplication of hard data like that, makes impossible to reference and clean up later.
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.
