3D Texture Mapping for Rapid Manufacturing

Inspired by the developments of biomimetic design and layer manufacturing, we present a microstructure design method which uses complex internal structures to achieve an optimal design. Similar to 2D texture mapping, our approach is based on mapping a 3D microstructure into a design space to generate internal structures. We develop a texture mapping design system which enables a designer to select a microstructure from a library. Accordingly the system automatically generates a CAD model of internal structures based on given design requirements. The system then combines internal structures with a given CAD model. The combined CAD model can be fabricated using a layer manufacturing system. The ability to design microstructures within a part creates tremendous potential for lightweight and high performance components and devices.
