Problems solved by technology

[0004] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides an electric field-driven fused jet deposition 3D printer, which introduces a new nozzle structure, breaks through the traditional fused deposition forming, and faces low precision and limited printing materials. EHD-based fused deposition printing Problems such as limited height and poor stability solve the problem that the nozzle is easy to be blocked after printing is interrupted

Abstract

The invention discloses an electric field driven fusion spraying deposition 3D printer and a working method thereof. By means of the electric field driven fusion spraying deposition 3D printer and theworking method thereof, the fusion deposition 3D printing resolution is low, printing materials are limited, sprayers are likely to be blocked, and high-resolution and micro-scale structure printingis difficult. A novel sprayer structure is introduced to the electric field driven fusion spraying deposition 3D printer, and low-cost and high-resolution fusion deposition forming is achieved. According to the technical scheme, the electric field driven fusion spraying deposition 3D printer comprises a bottom plate, a Y-axis workbench is arranged on the bottom plate, a printing platform is fixedto the Y-axis workbench, a sprayer module and a vertical observing camera are correspondingly arranged above the printing platform, the sprayer module and the vertical observing camera are connected to a Z-axis workbench, and the Z-axis workbench is fixed to an X-axis workbench; and a squinting observing camera is correspondingly arranged on one side of a printing nozzle, and an LED light source is correspondingly arranged on the other side of the printing nozzle.

Description

technical field [0001] The invention relates to the technical fields of additive manufacturing and 3D printing, in particular to an electric field-driven fusion jet deposition 3D printer and a working method thereof. Background technique [0002] Fused deposition modeling (FDM) is a 3D printing process based on material extrusion. FDM has the remarkable characteristics and advantages of high material utilization, low cost, simple process and clean production. At present, FDM has been used in aerospace, home appliances, automobiles, medical , mould, education, construction and many other fields have been widely used. However, the biggest problem facing FDM at present is low precision, limited types of printing materials, and the inability to achieve high-precision and high-resolution structure / product printing. The further improvement of FDM processing accuracy is affected and restricted by many factors such as layer thickness, print nozzle size, print resolution, and print ...
