Multi-form extruding method of 3D printer

Abstract

The invention discloses a multi-form extruding method of a 3D printer. The method comprises the following steps that a central flow channel in the center of a valve core body receives solid raw materials or molten raw materials, when the central flow channel receives the solid raw materials, heat energy can be transferred to the central flow channel through a heat source arranged outside the valve core body, and the solid raw materials located in the central flow channel can be melted; when the valve core body moves in a vertical direction and a first flow channel and bias flow channels are communicated, the molten raw materials in the central flow channel can flow into the bias flow channels through the first flow channel, and the molten raw materials can be extruded and formed through discharging ends of the bias flow channels; and when the valve core body moves in the vertical direction and the first flow channel and a second flow channel are communicated through an annular groove, the molten raw materials in the central flow channel can pass through the first flow channel, the annular groove and the second flow channel and are extruded and formed through an extruding flow channel.

Description

technical field [0001] The present invention relates to 3D printer technology. Background technique [0002] 3D printing has brought about a global manufacturing revolution. In the past, component design was completely dependent on whether the production process could be realized. The emergence of 3D printers will subvert this production idea, which makes enterprises no longer consider production when producing components. Process issues, the design of any complex shape can be realized by 3D printer; 3D printing can directly generate objects of any shape from computer graphics data without machining or molds, thus greatly shortening the production cycle of products and improving production efficiency. productivity. Although it still needs to be perfected, the market potential of 3D printing technology is huge, and it is bound to become one of the many breakthrough technologies in the future manufacturing industry. [0003] As far as the current 3D printing technology is co...

AI Technical Summary

Problems solved by technology

[0003] As far as the current 3D printing technology is concerned, the extrusion mechanism of the 3D printer has a single shape and can only print in one state. It cannot effectively switch between printing with different features, which is also the key to restricting printing efficiency.
