Abstract Scope |
Large Language Models (LLMs) enable the creation of up-to-date material property databases, offering significant potential for identifying materials with desired properties, proposing alternatives to costly options, resolving discrepancies in reported values, and automating inputs for tools like Finite Element Analysis (FEA). This work explores Multimodal Retrieval-Augmented Generation (RAG) for extracting information from Wire Arc Additive Manufacturing (WAAM) and Sheet Moulding Compound (SMC) documents. Given that material property data is often tabular, a benchmark was developed for parsing tools capable of handling diverse PDF layouts. Tables, images, and text were extracted using multimodal embeddings and table2text techniques, enabling the retrieval of relevant material information. The extracted data was processed into structured formats, including automatic detection and conversion into SI units, and LLM outputs were evaluated using standard metrics, as well as a custom metric. These advancements enhance workflow efficiency and decision-making by providing rapid, traceable access to manufacturing information. |
