Additive Manufacturing

Overview

Additive manufacturing, also known as 3D printing, enables the rapid fabrication of metal components in a wide range of compositions, shapes, and sizes. The process occurs at high speeds and involves intense thermal gradients. Its extremely bright core poses a major challenge for camera-based imaging systems. Advanced illumination techniques make it possible to visualize these processes clearly by reducing the overwhelming brightness, allowing researchers to observe the operation as if it were cold. These imaging approaches are applicable to all arc- and laser-based additive manufacturing and metal 3D printing methods. High-speed infrared imaging also offers valuable insights into additive manufacturing, supporting fundamental research in heat transfer and process monitoring with high spatial, thermal, and temporal resolution.
