Automatically Designing and Printing 3-D Objects with EvoFab 0.2

Tim Kuehn, John Rieffel


Although Evolutionary Design has had great success in creating virtual objects, very few of these evolved designs have been manufactured. Standing in the way is the fabrication gap caused by a reliance on prescriptive rather than descriptive representations of evolved objects. Evolutionary Fabrication describes an alternative process which evolves how rather than what to build. In this paper we describe EvoFab 0.2, a completely automated physically embodied machine which implements Evolutionary Fabrication and evolves three dimensional objects. We describe the mechanism and underlying algorithms in detail, and show how it can be used to create novel structures.
