A Design Modeling Framework for Multi-Material Biopolymer 3D Printing

This paper presents a novel design-to-fabrication pipeline for multi-material3D printing. The pipeline is based on a multi-resolution grid-based approach that allows multiple data values to be stored and computed locally. Integrating contextual data, generative algorithms and print path generation, our pipeline incorporates efficient data storage and manipulation, seamless integration with existing digital workflows, advanced volumetric operations, and scalability to accommodate different scales of volumetric data. We demonstrate and assess the application of this workflow in the design and fabrication of Radicant, a biopolymer-composite wall system, exemplifying the possibilities of utilizing diverse materials and efficient modeling and fabrication techniques.
