Embodiment Construction

[0036] The present invention will be further described below in conjunction with the drawings and implementation process.

[0037] Such as figure 1 As shown, a three-dimensional printer with replaceable nozzles includes a chassis frame 11, and an X-axis adjustment mechanism, a Y-axis adjustment mechanism, and a Z-axis adjustment mechanism installed on the chassis frame 11 .

[0038]The Y-axis adjustment structure includes a Y-axis stepping motor 7 fixed in the longitudinal direction of the chassis frame 11 , a Y-axis guide rail 10 , and a Y-axis lead screw 9 installed above the Y-axis guide rail 10 . The X-axis adjustment mechanism includes an X-axis guide rail 5, an X-axis stepping motor 8 and an X-axis screw 4, and the Y-axis screw 9 drives the X-axis guide rail 5 to move in the Y direction through thread engagement. An X-axis stepper motor 8 and an X-axis lead screw 4 are installed on the X-axis guide rail 5 . The Z-axis adjustment mechanism includes a Z-axis guide rail 3...

Abstract

The invention discloses a three-dimensional printer with a replaceable nozzle. The three-dimensional printer comprises a three-dimensional adjusting mechanism, and the printing nozzle which performs three-dimensional printing under the adjustment of the three-dimensional adjusting mechanism, wherein the printing nozzle comprises a nozzle bottom plate, a nozzle thermal preservation sleeve which is fixed on the nozzle bottom plate and is provided with a printing through hole and a positioning notch, a material tube which is radially clamped on the nozzle bottom plate, and a linear stepping motor; the material tube is axially clamped in the positioning notch through a material tube pressing plate which is in sliding fit with the nozzle bottom plate; a piston presser used for pushing a piston in a first material tube is fixed at the output end of a lead screw of the motor. When materials in the material tube are used up or the materials are needed to be replaced, the printing nozzle is controlled to automatically replace the material tube, and a three-dimensional object consisting of multiple materials can be printed. The piston is driven to be extruded by adopting the linear stepping motor, thrust is high and can be accurately controlled, and the blockage of the nozzle is avoided. According to the printer, liquid foods and multiple liquid materials such as gel and ceramic powder can be printed.

Description

technical field [0001] The invention belongs to the field of three-dimensional printing equipment, and in particular relates to a three-dimensional printer with replaceable nozzles. Background technique [0002] Three-dimensional printing is an emerging technology that has developed rapidly in the manufacturing industry in recent years, and its main process is layer-by-layer printing. The system automatically layers the 3D modeling with a certain layer thickness. The print head prints layer by layer according to the data of each layer, and finally each layer of material is stacked into a three-dimensional entity. Compared with traditional manufacturing methods, 3D printing can manufacture parts with more complex shapes. [0003] With the development of science and technology and social progress, there are more and more types of 3D printing platforms. The main technologies are as follows: selective laser sintering, fused deposition modeling, stereolithography, layered entit...
