Objective

Develop a fast and flexible framework for generating 3D microstructures with user‐defined characteristics, such as volume fractions and tortuosities, to support customizable and efficient material design.

Background

Microstructures are essential for material performance across ceramics, polymers, and semiconductors. Studying structure‐property relationships requires a diverse and extensive dataset of microstructures. Experimental and statistical methods are expensive, inflexible, and challenging for large‐scale generation.

Key Contributions

1. Developed a framework for diverse 3D microstructure generation.
2. Enabled conditional generation with user‐specified volume fractions and tortuosities.
3. Integrated manufacturing parameter prediction for generated microstructures.
