An electric field driven melt jet deposition 3D printing method

Abstract

The invention relates to the technical field of printers, in particular to an electric field driving fusion jet deposition 3D printing method. According to the method, a fusion jet deposition 3D printer adopted by the printing method adopts a separated operation table, operation personnel can conveniently clean the operation table, the cooling and solidification speed of fused material can be accelerated through the arrangement of a water storage tank, the operation table can be driven to move up and down through a moving mechanism so as to meet the requirement of three-dimensional processing,and a raw material line is prevented from being pulled broken; a cutting mechanism can quickly cut off a base of a workpiece after the processing is finished, follow-up operation is not needed, the height of the cutting mechanism can be adjusted according to the height of the base, and the application range is wide; and the raw material line can be protected and guided through a conveying mechanism, the conveying process of the raw material line is more smooth and not interrupted, and the flowing speed of the raw material line can be increased through the arrangement of a second rotating motor.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to an electric field-driven fusion jet deposition 3D printing method. Background technique [0002] Electric field-driven melt jet deposition 3D printer is a melt extrusion molding technology, also called melt accumulation molding. The basis of this process is to heat and melt thermoplastic polymer materials into filaments, extrude from the nozzle like squeezing toothpaste, and accumulate on the molding surface. For upper molding, the equipment covers different application areas from building fast concept models to slow high-precision models. The materials are mainly polyester, ABS, elastomer materials, and wax for investment casting. [0003] During the printing process, the raw material line will be pulled to the processing head for melting and discharge, but the current printing equipment lacks the guide and protection device for the raw material line, which makes the raw materi...

AI Technical Summary

Problems solved by technology

[0003] During the printing process, the raw material line will be pulled to the processing head for melting and discharge, but the current printing equipment lacks the guide and protection device for the raw material line, which makes the raw material line easy to be polluted or broken; when printing at different heights , mainly because the processing head moves up and down, which will cause the pulling force on the raw material line to change, making the traction and transportation unstable; after the processing is completed, the workpiece needs to be removed by other equipment to remove the workpiece base, which is troublesome and does not need to be realized once. forming
