[0002] CT scans use X-ray beams to scan a certain thickness of a part of the human body. The detector receives the X-rays that pass through the layer, converts them into visible light, then converts them into electrical signals through photoelectric conversion, and finally converts them into digital signals through an analog-to-digital converter, which then inputs them into a computer for processing.

[0003] However, in the current technology, when using mechanical testing devices for real-time detection during CT scanning, compression, bending, and tension are mostly used to inspect the surface of the formed items. However, the internal structure cannot be effectively detected, which means that the peak values ​​of particle changes inside the item cannot be detected in real time. As a result, operators cannot intuitively understand the structural characteristics of the relevant mechanical properties of the item. Therefore, it is necessary to propose a new high-precision in-situ real-time mechanical property monitoring device based on CT scanning. Summary of the Invention

[0032] The operation and working principle of this device are as follows: First, when performing real-time monitoring of the in-situ mechanical properties of a CT scan, the operator uses the wiring converter 6 to establish a data signal connection between the external CT scanner and the photopolymer 3D printer 3. This allows the photopolymer 3D printer 3 to use photosensitive resin to perform 3D printing of the data image scanned by the CT scanner, facilitating subsequent mechanical property testing and monitoring. After printing, the reciprocating traction conveyor 4 and the single-layer conveyor 8 are started. The single-layer conveyor 8 drives the traction plate 7 to rotate in the forward direction, transporting the printed item to the preset position. Then, with the cooperation of the hydraulic structure 99, the pressure plate 994 drives the three sets of reinforcing ribs 995 and the placement plate 997 in a locking and lifting motion. The nozzle 19 is raised to a preset height. Then, the first mechanical automatic arm 23, after adjustment, drives the automatic hydraulic clamp 24 to clamp and compress the printed item, allowing the deformation force peak data to be detected with the cooperation of two sets of dynamic tension and compression sensors 11. Then, with the cooperation of the ball bearing guide 12, the sliding seat drives the single-axis compressor 25 to adjust left and right, so that the single-axis compressor 25 can drive the stress block 26 to perform stress and pressure mechanical operations on the printed item. Under the action of multiple sets of stress and strain sensors 27, in conjunction with the automatic steering base 17, the steering adjustment angle motor 20 drives the second mechanical automatic arm 21 and the three-dimensional forming... The scanner 22 is adjusted and rotated to facilitate the second mechanical automatic axis arm 21 driving the 3D imaging scanner 22 to perform full-angle scanning and detection of the object after the mechanical experiment. This facilitates the conversion of the detection data into numerical values ​​on the imaging detection display screen 16 for real-time monitoring by the operator. Then, the hydraulic structure 99 drives the pressure plate 994, three sets of reinforcing ribs 995, and the placement plate 997 to descend inside the fitting lifting port 19. Next, under the action of the electric push rod 993, the hydraulic structure 99 retracts outside the four stable guide rods 992. Then, the forward and reverse adjustment motor is started, driving the adjustment screw 95 to move under the cooperation of the bearing seat 93 and the two guide columns 94, causing the dual-axis pneumatic cylinder 98 to move from the limit position. After sliding inside the chute 97 to the bottom of the fitting lifting port 19, it stops. Then, the dual-axis pneumatic cylinder 98 drives the magnetic particle emitter 9901, multiple sets of memory plastic contacts 9903, contact end 9904, and target emission end 9905 to rise inside the fitting lifting port 19. Next, the first mechanical automatic axis arm 23 drives the automatic hydraulic clamp 24 to adjust it above the magnetic particle emitter 9901, causing the automatic hydraulic clamp 24 to release, allowing the printed material after the mechanical test to fall onto the surface of the contact end 9904 and the target emission end 9905. Then, the single-axis compressor 25 adjusts the downward pressure of the stress block 26 on the printed material, causing the single-axis compressor 25 to drive the stress block 26 to press down on the placed printed material.Then, with the cooperation of multiple sets of memory plastic contacts 9903 and contact ends 9904, an outward contact surface is formed. Next, the magnetic particle emitter 9901 is activated, causing the target emitter 9905, which contacts the contact end 9904 and the outer surface of the printed object, to emit magnetic particles. These particles enter the cracks created on the surface of the printed object after the mechanical experiment. Utilizing the superparamagnetism of the magnetic particles, they accumulate and form from within the printed object. Then, with the cooperation of the magnetic sensor 9902, the second mechanical automatic arm 21 drives the 3D imaging scanner 22 to perform scanning operations and transport the scanned material to the imaging detection display screen 16. This facilitates high-precision real-time monitoring of the peak values ​​of in-situ mechanical property changes within the printed object, helping operators to intuitively understand the structural characteristics of the object's relevant mechanical properties. Then, the first mechanical automatic arm 23 drives the automatic... The hydraulic clamp 24 re-clamps the printed item, then the dual-axis pneumatic cylinder 98 descends. With the assistance of the forward and reverse adjustment motor, the dual-axis pneumatic cylinder 98 drives the magnetic particle emitter 9901 and related structures back into the limiting slide groove 97. Next, the electric push rod 993 operates again, causing the hydraulic structure 99 to lift the aforementioned structures. The automatic hydraulic clamp 24 then places the printed item back onto the surface of the rotating disk 999. The brushless motor 996 then starts, and with the cooperation of the annular guide rail 998 and the rotating disk 999, the printed item rotates at an angle. The automatic hydraulic clamp 24 then clamps it again, and the dual-axis pneumatic cylinder 98, with the assistance of the forward and reverse adjustment motor, performs displacement and then lifts it. This process is repeated until high-precision real-time monitoring of the peak values ​​of in-situ mechanical property molding data changes inside the printed item is achieved.
