Aim To study the detection technique of temperature of polymer coated porcelain powders in the process of line scanning laser sintering. Methods To detect the temperature of sintered layers with the infrared thermometers and thermcouples ,then to compare the results with the calculation values. Results The experiment values were in good agreement with the calculation values. Conclusion With the system of temperature detection developed in this paper, the temperature could be detected rapidly and precisely, the basis of next analyzing of deforms, stresses and defects was made firmly.
