Embodiment
[0060] The invention discloses a real-time in-situ measurement device for powder bed fusion additive manufacturing, which can measure the temperature history and deformation of a specific position on a substrate during the additive manufacturing process.
[0061] Taking the selective laser melting in the powder bed fusion technology as a representative, it is explained how the present invention realizes in-situ real-time and accurate measurement of temperature by means of a data measuring device in the process of additive manufacturing. Such as figure 1 As shown, during the processing, the thermocouple monitors the temperature, and the measurement data is recorded and analyzed by the corresponding data recorder 6 .
[0062] When installing, install the lower bracket 8, the displacement sensor fixing plate 9, and the upper bracket 10 from bottom to top on the lifting platform 7 of the forming room, then install the workbench 5 on the upper bracket 10, and finally install the 50...
