Abstract
This paper introduces a data-driven process for designing and fabricating
materials with desired deformation behavior. Our process
starts with measuring deformation properties of base materials. For
each base material we acquire a set of example deformations, and
we represent the material as a non-linear stress-strain relationship
in a finite-element model. We have validated our material measurement
process by comparing simulations of arbitrary stacks of base
materials with measured deformations of fabricated material stacks.
After material measurement, our process continues with designing
stacked layers of base materials. We introduce an optimization process
that finds the best combination of stacked layers that meets a
user’s criteria specified by example deformations. Our algorithm
employs a number of strategies to prune poor solutions from the
combinatorial search space. We demonstrate the complete process
by designing and fabricating objects with complex heterogeneous
materials using modern multi-material 3D printers.
