3D printing post-processing temperature measuring device and method

The invention discloses a 3D printing post-processing temperature measuring device and method. The 3D printing post-processing temperature measuring device comprises a sensor fixing frame, a temperature measuring cable, a temperature displayer and temperature sensors. The plurality of temperature sensors are uniformly distributed on the sensor fixing frame in a covering manner; each temperature sensor is connected with a temperature measuring cable, and the free end, away from the corresponding temperature sensor, of each temperature measuring cable is connected with the temperature displayer and used for checking the temperature of the corresponding temperature sensor in real time. The quantitative relation between the 3D printing sand mold glass bead burying depth and the baking time is achieved, the baking time needed by any 3D printing sand mold burying depth can be accurately mastered, the situation that the baking time is mastered inaccurately is avoided, the probability that the 3D printing sand mold p
