Paragraph starter

The adoption of metal additive manufacturing for high-value applications is significantly hindered by the lack of robust quality assurance mechanisms. Unlike established manufacturing processes, current metal AM systems often lack integrated in-situ monitoring capabilities, making it difficult to detect and address defects during the build. Research into advanced instrumentation and adaptive control strategies is crucial for developing factory-ready AM processes that can provide the necessary assurance of component integrity.
