Problems solved by technology

The 3D printing model in the prior art sometimes contains some symmetrical elements, and even the whole model is a symmetrical structure. When printing this kind of three-dimensional model, the nozzle prints a section and repeats the same path several times, which not only affects printing efficiency, but also And it will increase the complexity of programming to a certain extent

Abstract

The invention belongs to the technical field of 3D printing, and particularly relates to a revolution sprayer assembly for a 3D printer. The revolution sprayer assembly comprises a connection part and a revolution part, the connection part is used for connecting a sprayer driving mechanism of the 3D printer, and the revolution part is rotatably arranged on the connection part along a vertical axis; at least two sliding blocks are arranged on the revolution part, each sliding block is arranged on the revolution part in a sliding mode in the direction of a radial line of a circular area that a revolution centre of the revolution part serves as a centre of a circle, and each sliding block is symmetrically and movably arranged around a symmetry point of the revolution centre of the revolution part in synchronism; and a sprayer is installed on each sliding block, and the position of each sliding block is arranged of the revolution centre of the revolution part in a centre symmetrical mode. The revolution sprayer assembly for the 3D printer comprises at least two sprayers moving symmetrically in synchronism, during printing, symmetrical structures on a model can be printed in synchronism, the printing time of the model is greatly shortened, and meanwhile, the process of programming is effectively simplified.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a rotary nozzle assembly of a 3D printer. Background technique [0002] 3D printer, also known as three-dimensional printer (3DP), is a cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file and uses special wax, powdered metal or plastic to bond materials, which create three-dimensional objects by printing layers of adhesive materials. At this stage 3D printers are used to manufacture products. The technology of constructing objects by printing layer by layer. The principle of a 3D printer is to put data and raw materials into the 3D printer, and the machine will build the product layer by layer according to the program. The 3D printing model in the prior art sometimes contains some symmetrical elements, and even the whole model is a symmetrical structure. When printing this kind of three-di...
