Process Analytical Technology (PAT)

Definition

Process Analytical Technology (PAT) refers to a system for designing, analyzing, and controlling manufacturing through timely measurements of critical quality and performance attributes. It enhances the understanding of processes by integrating real-time monitoring and control, which is especially relevant for advanced manufacturing techniques like 3D printing. This approach promotes efficiency and ensures product quality by allowing for adjustments based on real-time data.
