Abstract

The invention relates to a 3D printing device and method based on the electromagnetic emission technique, and belongs to 3D printing devices and methods. An XY-direction workbench and a support are mounted on a base, a Z-direction workbench is connected with the support in a sliding mode, and a connecting frame is connected with the Z-direction workbench and a sprayer. A high-precision injection pump is fixed to the base. The two ends of a feed pipe are fixedly connected with the sprayer and the high-precision injection pump correspondingly. A piece bearing table is mounted on the XY-direction workbench and located below the sprayer, and a substrate is connected to the piece bearing table. Current and a magnetic field are exerted on conductive liquid in the sprayer, the conductive liquid is pushed by ampere force to be sprayed out to a designated position, the magnitude of the ampere force serving as pushing force can be changed conveniently by changing the current intensity or the magnetic field intensity, and therefore the ejection speed of printing liquid drops is controlled; and a nozzle is prevented from being blocked by giving the magnetic field intensity and current duration and controlling the current intensity, high printing precision can be achieved, and the 3D printing device and method are suitable for 3D printing of biological conductive materials and non-biological conductive materials.

Description

technical field

[0001] The present invention relates to a 3D printing device and method, in particular to a 3D printing device and printing method based on electromagnetic emission technology. Background technique

[0002] 3D printing is a high-tech material accumulation and forming based on digital models. It is a new manufacturing method that combines digital manufacturing, layered manufacturing, stacking manufacturing, direct manufacturing, and rapid manufacturing. Due to the high customization and fast manufacturing speed of 3D printing, it has broad application prospects in mold manufacturing and product development, but due to the high-viscosity liquid printed in current 3D printing technology, high printing accuracy and printing speed cannot be guaranteed. However, when printing high-viscosity liquid droplets, nozzle clogging is easy to occur; therefore, solving the problems of low precision, slow speed, and easy clogging of nozzles in the printing process of high-vis...
