Prototype / Concept Model

An object made to test a design idea, communicate intent, or fail visibly so the next version can be better. The reason 3D printers, foam, and shop-time exist in design programs. Constraints are looser than production: appearance, ergonomics, and proof-of-mechanism dominate over per-unit cost.

mechanical

  • sufficient stiffness to demonstrate intent
  • survives photo-shoot and review handling

environmental

  • short service life — typically days to weeks

regulatory

  • none — internal use unless tested with users (then IRB / consent applies)
