Description

Technical Field

[0001] The present invention relates to the technical field of 3D printers, in particular to a high-speed 3D printer with high bonding strength and its printing method. Background Art

[0002] A 3D printer refers to a three-dimensional solid printer, which is a rapid prototyping process. It uses a layer-by-layer stacking method to fabricate a three-dimensional model layer by layer. Its operation process is similar to that of a traditional printer. The only difference is that a traditional printer prints ink on paper to form a two-dimensional flat drawing, while a three-dimensional printer forms a three-dimensional entity by spraying a binder or extruding materials such as liquid photosensitive resin materials, molten plastic filaments, and gypsum powder to achieve layer-by-layer stacking.

[0003] For example, the publication number is: CN214239547U, a rapid 3D printer, including a printer main body, which is composed of a scanning box and a printing box. The top of one end of the printing box is fixedly connected with a switch board. On one side of the switch board, a first switch, a second switch, a third switch, and a fourth switch are fixedly installed in sequence from top to bottom. The bottom of one end of the printing box is fixedly connected with a scanning box. The corners of the inner wall bottom of the printing box are all fixedly installed with electric telescopic rods. The output ends of the four electric telescopic rods are respectively fixedly connected with the corners of the bottom of the base. A rapid 3D printer can directly scan existing items through a scanner and then print them. The operation is simple and fast, which can accelerate the printing efficiency. Through a cooling fan, it can continuously ventilate the inside of the printing box during the printing process, which can accelerate the cooling process of the printed parts and improve the printing efficiency. Through a working board, it is convenient to clean the inside of the printing box.

[0004] However, when in use, when rapid printing is required, the printing speed is relatively low. And when in use, sometimes multiple nozzles are used for printing. But when in use, the same set of drives is used to adjust the positions of the nozzles, there is a problem of mutual interference, which affects the printing efficiency. And when in use, it is impossible to quickly locally cool the printing materials ejected from the nozzles, resulting in easy deformation and low bonding strength. And after printing is completed, natural cooling is mostly used, and it is impossible to warm the formed printed products, resulting in poor bonding strength and affecting the use.

Micro electric telescopic rods (709) are uniformly and fixedly installed at the upper end of the water injection box (701). The extending ends of the micro electric telescopic rods (709) extend into the water injection box (701) and are fixedly connected to the upper surface of the heat conduction pipe (707). Two communication holes (7010) are opened at the upper ends of the heat conduction pipe (707). The heat conduction pipe (707) is connected to the water injection box (701) through the communication holes (7010).

7. A printing method of the high-speed 3D printer with high bonding strength according to any one of claims 1 to 6, characterized in that: When in use, it includes the following steps: Step 1: Transmit the original file to be printed into the control unit (8), and place the printing raw material inside the feeding assembly (5); Step 2: The driving assembly (3) adjusts the position of the printing assembly (4), extrudes the printing raw material through the printing assembly (4), forms it on the bearing plate (2), and improves the printing speed through two printing nozzles (402) during printing; Step 3: When forming, the temperature control assembly (6) injects cold air into the cooling assembly (7) for cooling, and preliminarily cools the bonding position through the cooling assembly (7); Step 4: After printing is completed, the temperature inside the housing assembly (1) is controlled by the temperature control assembly (6) for slow cooling to achieve a temperature maintenance effect and improve the bonding strength.
