Why is Digital Fabrication relevant?

Additive Manufacturing (AM) technologies are posing the question: How design could take advantage of AM digital fabrication technology? This is feeding the discussion in a broader sense: How digital fabrication technology could impact on manufacturing processes and the exploration of the design space?

Why isn't Digital Fabrication plug-and- play?

(YET)

MAIN GAP: Digital/Virtual worlds lack of physicality! MAIN GAP: Technology limitations

Our work focus on this gap!!!

What is Functional Fabrication?

Functional Fabrication comprises the design and manufacture of physical

  • bjects with functionalities by means of

digital fabrication technologies. These functionalities include:

  • Mechanically enhanced workpieces,
  • Articulated physical models,
  • Aerodynamic workpieces,
  • Deformable workpieces and
  • Object’s with controlled appearance

and acoustics.

What role CG community plays?

Recent design tools are clearly taking advantage of relevant computer graphics techniques and extending these techniques to realise new physical forms as well as bringing innovation to feed into the design space. That is: Guiding the exploration of the feasible design space!
