  3. Fabricational Complexity • Total Complexity • Complexity Per Unit Volume • Complexity Per Unit Time*Energy • Complexity Per unit Cost Ffab = ln (W) / [ a3tfab Efab ] Ffab = ln (M)e-1 / [ a3tfab Efab ]

  4. Fabricational Complexity …Can we use this map as a guide towards future directions in fabrication?
