| summary |
At present, computer aided design (CAD) software has proven ill equipped to manage the spatial variations in material properties. Most digital design packages employ a surface modeling paradigm where a solid object is that which is enclosed by a set of boundaries (known as boundary representations or “B-rep” for short). In surface models, material representations are often treated as homogenous and discrete. Yet, natural materials are capable of structures where the variability of material within a volume is defined at a multiplicity of scales and according to various functional criteria. With the advent of new 3D printing techniques, a new possibility emerges—allowing new multi-material composite objects to be fabricated in a single build volume with a high degree of dimensional accuracy and repeatability. However, a big limitation facing complex high resolution digital fabrication comes from the software’s inability to represent or handle material variability. This paper proposes a new digital interface for working with multi-material distributions at a variety of scales using a rasterization process. Beyond the immediate benefit of precise graduated control over the material distribution within a 3D printed volume, our interface opens new creative opportunities by enabling the use of existing image processing techniques (such as filtering, mapping, etc.) which can be applied to three-dimensional voxel fields. Examples are provided which explore the potential of multi-scale material distributions. |
