Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of 3D printing, and in particular to a device for detecting the printability performance of 3D printing materials. Background Art
[0002] 3D printing technology, also known as additive manufacturing, is a rapid prototyping technology based on digital model files. It uses bondable materials such as powdered metal or plastic to construct objects by printing layer by layer. This technology is realized through digital technology material printers, and its core principles cover three main aspects: modeling, materials, and stacking. In terms of materials, the materials used in 3D printing need to have a certain degree of fluidity and stackability so that the printer can print them layer by layer into a solid object. These materials can be plastics, metals, ceramics, etc. Different materials require different printing processes and parameters to ensure the printing effect and quality.
[0003] In the 3D printing process, the printability of cementitious materials is a key factor affecting the printing quality and accuracy. At present, there is a lack of a unified standard or a test method that can be quantified for evaluation. The judgment of the printability of cementitious materials mainly involves aspects such as the material's fluidity, curing performance, coagulation time, material strength, and the appearance of the hardened body. Therefore, when judging the printability of cementitious materials, it is necessary to comprehensively consider the above aspects and conduct actual printing tests to evaluate the printability of cementitious materials. It should be noted that different types of cementitious materials have different physical and chemical properties and printing characteristics, and different printing processes have different requirements for the printability of cementitious materials. Therefore, in actual applications, it is necessary to make judgments based on specific circumstances.
[0004] In summary, the determination of the printability of gelling materials is a process that comprehensively considers multiple factors. Therefore, a device for detecting the printability of 3D printing materials is proposed. Utility Model Content

[0021] An extrusion port is provided at the bottom of the extrusion working chamber 7, and the diameter (or printing thickness) of the extrusion port is d. The extrusion port and the extrusion working chamber 7 are detachably connected by threads, and the corresponding specifications can be selected and replaced according to needs.
[0022] The extrusion assembly includes a first drive motor 4 fixed on the upper surface of the support top plate 3. The driving end of the first drive motor 4 extends to the bottom of the support top plate 3 and is fixedly connected to a threaded rod 5. A threaded sleeve is provided on the outer surface of the threaded rod 5. An extrusion plate 6 is fixed to the bottom end of the threaded sleeve. When in use, the first drive motor 4 rotates to drive the threaded rod 5 to rotate, and the threaded rod 5 can drive the threaded sleeve and the extrusion plate 6 to move downward to extrude materials. In order to avoid the threaded sleeve and the extrusion plate 6 from rotating at the same time when the threaded rod 5 rotates, a groove can be provided on the surface of the extrusion plate 6, and a raised slideway can be provided on the inner wall of the working bin to limit the extrusion plate 6.
[0023] The lifting and rotating dial 8 includes a dial body 81 and a lifting and rotating mechanism arranged inside the base 1. The lifting and rotating mechanism includes a second driving motor 84 fixed on the inner top wall of the base 1. The driving end of the second driving motor 84 is fixed with a first pulley 88. The inner bottom wall of the base 1 is rotatably connected with a second pulley 87. A belt 85 is arranged between the second pulley 87 and the first pulley 88. A lead screw 86 is fixed to the inner bottom wall of the base 1. The lead screw 86 is located at the center of the second pulley 87. A lead screw sleeve 83 is arranged on the outer surface of the lead screw 86. The top of the lead screw sleeve 83 is fixedly connected to the dial body 81. A telescopic rod 82 is fixed between the dial body 81 and the second pulley 87. When used, the second driving motor 84 is started. The second driving motor 84 drives the second pulley 87 to rotate under the action of the belt 85, so that the second pulley 87 drives the dial body 81 to rise. When rotating, the lead screw sleeve 83 also rotates on the surface of the lead screw 86, so that the dial body 81 rotates and moves up at the same time.
[0024] The scale plate body 81 is a stainless steel disc with a radius of 15 cm, arranged 20 mm below the extrusion port and 30 mm away from the center of the circle, and has scale marks every 30° on its surface.

After the device is finished working, the material printing path is calculated by the scale of the lifting and rotating dial 8, the material accumulation state is observed, the deformation degree is measured, and the printability of the material is determined. The parts and components in the device are all made of 304L stainless steel.
[0026] The control panel 10 has a built-in microcomputer, which can synchronize the vertical movement speed according to the rotation speed of the liftable rotating dial 8. The microcomputer parameter control principle is: in conjunction with the rotation speed of the liftable rotating dial 8, the vertical displacement is d for one circle.
[0027] Working principle: Add the material into the working chamber 7 of the device, and extrude the material to the lifting and rotating dial 8 through the extrusion component. During the process of the dial body 81 rotating and descending, the material will be continuously stacked along a circular path. When the device is finished working, the material running path can be calculated by the angle of the dial body 81, and the state of collapse can be calculated by measuring the stacking height (the default height of each layer is the diameter d). The printability of the material can be judged by these two data.
[0028] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
