## Summary

James DeMuth, Co-Founder & CEO of Seurat Technologies, explains how his company’s 'area printing' technology disrupts metal additive manufacturing by increasing throughput to compete with conventional methods like casting and machining. He details the technical limitations of legacy laser powder bed fusion, such as speed and variability, and describes Seurat’s parallel laser approach that reduces production time from years to days. DeMuth discusses the economic implications for US manufacturing, arguing that high-volume additive can reshape supply chains by enabling local production and reducing inventory, while calling for public-private partnerships to counter Chinese subsidies.
