Additive manufacturing technologies makes it possible to control the target deformability behavior of
global geometry by varying the material deposition of microstructure. This offers new ways to
fabricate cellular materials with differentiated material behaviors that go beyond mimicking the
structure and mechanical properties of materials found in nature. However, material limitations and a
lack of appropriate design tools and models have confined the usefulness of 3D printed cellular
materials. This paper introduces and describes a novel design model that allows to analyze and exploit
microstructures in the context of architecture. Specifically, this paper discusses the use of 3D cellular
microstructures to fabricate flat deformable panels with predefined elastic behavior that can be used in
architecture to approximate arbitrarily complex shapes. In the first part this paper will introduce and
describe the design tool, which was developed by an interdisciplinary research team, comprising
researchers from architecture, computer graphics and civil engineering. The model takes into account
parameters affecting the structural response of 3D cellular microstructures, such as the volume
fraction, orientation distribution, aspect ratio within each cell as well as the cell geometry and relative
density are included in the model. To guide the design of cellular microstructures, we developed an
integrated, parameterized, multi-scale model. Computational homogenization based on finite element
is employed to obtain the elastic properties of the material at multiple scales. In the second part of this
paper, we will discuss the findings of a case-study undertaken by the authors in which the previously
described approach was employed and tested.

Using Marcel Breuer's iconic Cesca chair as a muse, the newly designed
chair illustrate the ability to ultilise robotic 3D printing processes of elastomeric materials to change the mechanical properties of the surface in response to anticipated load conditions.
