[0027] Among them, the user interface module 1 inputs printing instructions through the interface, including selecting model files, setting printing parameters, etc., and the control system set in the user interface module 1 is responsible for parsing these instructions. The melted materials of the print head module 3 and the feeding module 4, such as plastic, metal or photosensitive resin, are extruded or solidified layer by layer to form a three-dimensional object. The feeding system is responsible for stably delivering the material to the print head. In ultra-high-speed 3D printing, the print head module 3 usually moves at a very high speed and accurately controls the extrusion amount of the material. The feeding module 4 stably delivers the material to the print head through a reel, a pump or a pressure system. The motion control module 5 is responsible for controlling the precise movement of components such as the print head and the printing platform to ensure the accuracy and stability during the printing process. In ultra-high-speed 3D printing, these systems need to work together at very high speed and accuracy. The printing module 6 serves as the bearing surface of the printed object. The printing platform remains stable during the printing process and may have heating or adsorption functions to ensure that the printed object can be firmly attached. The molding ring module 9 is responsible for providing a suitable printing environment, including temperature, humidity, light and other conditions to ensure the normal curing and molding of the printed material. The modeling module 7 and the slicing module 8 are responsible for converting the 3D model data input by the user into slice data that the printer can understand. These slice data will guide the actions of the print head and motion control system. The post-processing module 10 will perform some post-processing operations on the product, such as removing support structures, grinding, polishing and coloring, to obtain the final product. The temperature sensor continuously monitors and adjusts the system temperature to prevent failures and ensure smooth printing. The bed leveling sensor ensures that the print bed is level to achieve perfect printing. The optical limit sensor helps the printer establish an accurate starting position and control the movement of the print head and print bed. The heating device may be directly integrated into the print nozzle or print bed, and transfers heat to the printing material by heat conduction. It can ensure that the printing material maintains proper fluidity during the extrusion process, thereby improving the printing accuracy and interlayer bonding. The cooling device plays a role in accelerating the solidification of the printing material during the 3D printing process. By rapid cooling, the deformation and shrinkage of the printed part can be reduced, and the dimensional accuracy and surface quality of the printed part can be improved. The lighting device can help the user observe the printing progress and printing effect so as to adjust the printing parameters in time. The cooling device is connected to the forming ring module 9 through an air duct, a fan or a refrigeration system.
[0028] Meanwhile, the molding annular module 9 needs to use an ultraviolet light source to solidify the liquid resin in photocuring molding, while in fused deposition molding, it is necessary to control the temperature of the print head and the printing platform to ensure normal extrusion and solidification of the material.
[0029] Working principle:
[0030] The user interface module 1 is the input end, and the user inputs printing instructions through the interface. The control system is responsible for parsing these instructions and converting them into action instructions for the print head module 3 and the motion control module 5 actuators. The modeling module 7 and the slicing module 8 in the conversion module 2 provide the three-dimensional model and slicing data required for printing. The motion control module 5 accurately controls the movement of the print head and the printing platform according to the slicing data, and monitors and adjusts the movement state to ensure accuracy and stability. The print head module 3 and the internal feeding module 4 stack the materials layer by layer into a three-dimensional object according to the instructions of the motion control module 5. At the same time, the feeding module 4 ensures a stable supply of materials. The forming ring module 9 provides a suitable printing environment to ensure the normal curing and molding of the printed materials. The post-processing module 10 performs necessary processing operations after printing is completed to obtain the final product.
[0031] In summary, the ultra-high-speed 3D printing method and system, through the print head module 3 moving at an extremely high speed and accurately controlling the extrusion amount of the material, cooperates with the motion control module 5 to ensure the accuracy and stability during the printing process, and then uses the molding ring module 9 to control the temperature of the print head module 3 and the printing module 6 to ensure the normal extrusion and curing of the material, thereby achieving the key to high-speed and precise printing. By continuously optimizing the design and performance of these modules, the speed and quality of 3D printing can be further improved.
[0032] The ultra-high-speed 3D printing method and system converts the three-dimensional model data input by the user into slice data that can be understood by the printer through the conversion module 2. The slice data will guide the action of the print head and the motion control system, which has the effect of significantly improving the printing speed, solving the printing path of the 3D printing method, as well as the material extrusion speed and the performance of the motion control system, and increasing the printing time, which means that the time for users to obtain the desired 3D printed products is extended, thereby reducing the problem of production efficiency.
