[0060] Specifically, in use, the PLC controller controls two groups of turning motors 11 to work synchronously, so that the turning motor 11 drives the turning plate 10 to rotate clockwise by 180° through the vertical plate 16, and the 3D printing substrate 9 on the turning plate 10 is inverted;

[0061] At this time, the four groups of infrared distance measuring probes 21 detect the distance from the inverted 3D printing substrate 9, once the height of the 3D printing substrate 9 is too low, the PLC controller controls the adjusting motor 64 to work, so that the lead screw 65 rotates clockwise to drive the lifting seat 61 to move downward, until the height of the molybdenum wire 28 is lowered to an appropriate position, that is, the molybdenum wire 28 is lowered to a height at which the molybdenum wire 28 can completely cut the 3D printing part 8 when cutting the 3D printing part 8;

[0062] Once the height of the 3D printing substrate 9 is too high, the PLC controller controls the adjusting motor 64 to work, so that the lead screw 65 rotates counterclockwise to drive the lifting seat 61 to move upward, until the height of the molybdenum wire 28 is raised to an appropriate position, that is, the molybdenum wire 28 is raised to a height at which the molybdenum wire 28 can completely cut the 3D printing part 8 when cutting the 3D printing part 8;
