Abstract

The invention discloses a printing head, a printing device and a printing method for rapid forming of a metal piece. The printing head comprises a body, a plurality of nozzles, a first electrode and a second common electrode. When the printing head is in the working state, electroplate liquid is sprayed out through the multiple nozzles and sequentially passes through the first electrode and the second common electrode. The printing device is provided with the printing head. According to the printing method, when electrochemical deposition or electrolytic etching is conducted on the electroplate liquid, the electroplate liquid is electrified and is directly sprayed onto a position needing to be printed; in the position which does not need to be printed, the electroplate liquid deflects when flowing through a deflection electric field by changing the electrical characteristic of the electroplate liquid, and the electroplate liquid is prevented from being sprayed onto the position which does not need to be printed. By the adoption of the printing head, the printing device and the printing method for rapid forming of the metal piece, the defects that a three-dimensional (3D) printer for the metal piece in the prior art is low in printing efficiency and low in precision are overcome, and rapid, high-quality and high-precision printing of 3D metal pieces is achieved.

Description

technical field [0001] The invention relates to the technical field of rapid prototyping, in particular to a printing head for rapid prototyping of metal parts, a printing device and a printing method. Background technique [0002] Rapid prototyping technology can directly accept product design (CAD) data without preparing any molds, cutting tools and fixtures, and quickly manufacture samples, molds or models of new products. Its basic principle is "manufacturing layer by layer, superimposing layer by layer", which is similar to the integral process in mathematics. [0003] With the rapid development of rapid prototyping technology, 3D printing is mainly realized in the following ways: [0004] 1. SLA body photolithography modeling technology [0005] Technical principle: use specific wavelength and intensity of laser light to focus on the surface of photo-curable material, so that it can be solidified in sequence from point to line and from line to surface. The lift tabl...
