Porosity remains a persistent challenge in metal additive manufacturing, with defects arising from everything from lack of fusion and keyholing to powder condition and process instability. We explore the main causes of porosity, why it can be difficult to control, and how in-process measurement can provide earlier insight into the conditions that lead to defects.

Understanding the difference between monitoring, inspection, and qualification is essential for scaling additive manufacturing from prototyping to production. While process monitoring provides visibility into machine behaviour and build conditions, inspection delivers direct, measurable data about part quality, and qualification establishes confidence that parts consistently meet required standards. This article explores how these three layers of additive manufacturing quality control work together, why monitoring alone is often insufficient for production environments, and how measurement-driven inspection bridges the gap between process data and qualification. Learn how advanced in-situ inspection technologies are helping manufacturers reduce uncertainty, improve process control, and accelerate the adoption of production-scale additive manufacturing.

In-situ inspection is transforming additive manufacturing by bringing real-time measurement and analysis directly into the build process. Instead of detecting defects after production is complete, manufacturers can now identify, quantify, and track issues layer by layer as they occur. This shift from reactive inspection to continuous process insight is helping aerospace, defense, and medical manufacturers improve quality, reduce inspection bottlenecks, and scale additive manufacturing with greater confidence.

Discover how quality assurance in additive manufacturing ensures consistent part quality through real-time monitoring, in-situ inspection, and data-driven process control. Learn why QA is essential for reducing defects, lowering costs, and enabling scalable production.
