In-situ measurement and monitoring of melt pool temperature using two-wavelength pyrometry with photodiodes in laser powder bed fusion

In-situ measurement and monitoring of melt pool temperature using two-wavelength pyrometry with photodiodes in laser powder bed fusion

<p dir="ltr">Melt pool temperature is critical for assessing component quality in laser powder bed fusion (LPBF), yet its high-precision in-situ measurement remains challenging due to rapid thermal cycles and material emissivity variations. This study developed a high-temporal-resolu...
