CrossMatAgent: AI‐Assisted Design of Manufacturable Metamaterial Patterns via Multi‐Agent Generative Framework

Year: 2025

Type: article

Abstract: Metamaterials, renowned for their exceptional mechanical, electromagnetic, and thermal properties, hold transformative potential across diverse applications, yet their design remains constrained by labor‐intensive trial‐and‐error methods and limited data interoperability. Here, we introduce CrossMatAgent—a novel multi‐agent framework that synergistically integrates large language models with state‐of‐the‐art generative AI to revolutionize metamaterial design. By orchestrating a hierarchical team of agents—each specializing in tasks such as pattern analysis, architectural synthesis, prompt engineering, and supervisory feedback—our system leverages the multimodal reasoning of GPT‐4o alongside the generative precision of DALL‐E 3 and a fine‐tuned Stable Diffusion Extra Large (XL) model. This integrated approach automates data augmentation, enhances design fidelity, and produces simulation‐ and 3D printing‐ready metamaterial patterns. Comprehensive evaluations, including Contrastive Language–Image Pre‐training‐based alignment, SHapley Additive exPlanations interpretability analyses, and mechanical simulations under varied load conditions, demonstrate the framework's ability to generate diverse, reproducible, and application‐ready designs. CrossMatAgent thus establishes a scalable, AI‐driven paradigm that bridges the gap between conceptual innovation and practical realization, paving the way for accelerated metamaterial development.
