Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a high-efficiency 3D printing device based on the characteristics of 3D printing materials. Background technique [0002] 3D printing technology is a rapid prototyping technology, based on digital models, using powdered metal or plastic materials to construct objects by layer-by-layer printing. Currently, it is widely used in industrial design and medical fields. Welcomed by the public. [0003] In the prior art, 3D printing melts the material when it is used, and prints according to the model after melting. In the prior art, the 3D printer is composed of a material barrel and an extrusion component. The material is melted and extruded by the material barrel and then printed. , but the 3D printer in the prior art also has the following defects in use: [0004] Since the 3D printing material is metal or plastic powder, it is placed in the material barrel to be me...

AI Technical Summary

Problems solved by technology

[0004] Since the 3D printing material is metal or plastic powder, it is placed in the material barrel to be melted and extruded for printing. However, due to the bonding force between the materials, the material is bridged in the material barrel to form a hollow structure, which makes the material unable to be extruded. As a result, raw materials are interrupted during printing, which affects the printing quality. Therefore, it is necessary to develop a 3D printer that can smoothly discharge materials to improve printing quality.
