The Role of Quality Engineering in Additive Manufacturing for Product Innovation

Abstract

Additive manufacturing (AM), commonly known as 3D printing, has become a game-change in product innovation, enabling designers and engineers to create complex geometries, reduce material usage, and accelerate prototyping. However, ensuring consistent product quality in AM poses significant challenges, including variability in mechanical properties, surface finish issues, and reproducibility concerns. Quality engineering provides structured methodologies to address these challenges through process optimization, statistical quality control, and robust design principles. This paper analyzes how Six Sigma, Taguchi methods, and real-time monitoring technologies can improve the reliability and repeatability of AM products. It further explores the role of advanced technologies such as AI, machine learning, and non-destructive testing in monitoring and ensuring quality in AM processes. By reviewing industrial practices in healthcare, aerospace, and automotive applications, the study demonstrates how integrating quality engineering frameworks with AM drives innovation while maintaining stringent quality standards.
