PROBLEM TO BE SOLVED: To provide a machine which is suitable for further reducing the occurrence of non-uniformity in sintering and sinters powders by using one temperature detecting surface by the laser beam. SOLUTION: This machine has an apparatus to compensate the error dependent on the position in detecting the temperature additionally. The apparatus takes into consideration at least one of the causes for the error, i.e., the change in the geometrical element of a moving detection surface, the color error when the laser beam L is different from the heat ray in the convergent intensity, and the adjustment error in coaxially adjusting the laser beam L and the heat ray depending on the position of the detection surface E on the surface of the powder P. |
