Microwave heating printing head for building 3D printing

Abstract

The invention provides a microwave heating printing head for building 3D printing. The microwave heating printing head comprises a material bin, a discharging pipe capable of absorbing microwave, a waveguide pipe, a magnetic control pipe and a power supply for providing high-voltage current for the magnetic control pipe, wherein a space for holding printing materials is formed in the material bin,and a discharging port is formed in the bottom of the material bin; the discharging pipe capable of absorbing the microwave is fixed to the discharging port; the waveguide pipe is fixed to the peripheral wall of the discharging pipe, the waveguide pipe has a hollow interior and an opening on one side, and an antenna inserting hole is formed in the side wall, opposite to the opening, of the waveguide pipe; an antenna inserted into the antenna inserting hole is arranged on the magnetic control pipe, and the magnetic control pipe is fixed to the waveguide pipe; and the magnetic control pipe generates microwave under the excitation of the power supply, the microwave is transmitted to the waveguide pipe through the antenna, and the waveguide pipe transmits the microwave to the discharging pipe. According to the microwave heating printing head, the printing materials in the discharging pipe are subjected to microwave heating, and quick forming of a printed component is facilitated.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a microwave heating print head for building 3D printing. Background technique [0002] The solidification and hardening rate of architectural 3D printing materials directly affects the quality of printed products. Fast solidification and hardening require multiple small quantities of printing materials to be prepared, and it is easy to block the pipeline. During printing, the equipment must run smoothly, the personnel should be closely coordinated, and the fault tolerance rate is low; slow solidification and hardening It can ensure that there is enough time to adjust the printing process, and the fault tolerance time is long, but the printed components are easy to collapse. How to control the setting and hardening time of printing materials is the key to architectural 3D printing technology. [0003] The most common 3D printers on the market use hot-melt resin as t...
