Temperature measurements during selective laser sintering of titanium powder

Numerical calculations performed with a model for the interaction of near infrared laser pulses with metallic powders are compared with the temperature measurement obtained with an infrared camera. Furthermore, a comparison of the temperature measurements between continuous wave sintering and pulsed sintering, is presented and the predicted difference of skin and average temperature upon Pulsed interaction is verified.
