Finally: a fully functional predecessor of your upcoming serial production is ready, touchable, palpable, operable! That doesn’t just spark emotions, it also enables you to test sustainability and acceptance in a real environment. Haptic models illustrate ergonomics and dimensions and still give you the opportunity for adjustments.
Usually in the first stages of the project paper sketches, plasticine models or Lego bricks are used, then 3D-printer function models, which serve for illustration and finally sintered parts, moldings or plastic-designs from soft metal tools give you the full scope of action.
The prototype is the king among models, because it not only allows a glimpse into the future, but it also is the last step towards serial production.
