Digital material 3D (Three Dimensional) printing head

Abstract

The invention discloses a digital material 3D (Three Dimensional) printing head. The digital material 3D printing head comprises a plurality of spaying heads, a plurality of ultraviolet lamps, a material supply system and a pneumatic control system, wherein the spraying heads are used for spraying resin liquid; central lines of the spraying heads are gathered on the same intersection point; the ultraviolet lamps are used for emitting ultraviolet beams and curing the resin liquid sprayed by the spraying heads; the material supply system is connected with the spraying heads and used for supplying the resin liquid for the spraying heads; the pneumatic control system is connected with the spraying heads and used for controlling the spraying action of the spraying heads. The digital material 3D printing head is capable of printing digital resin material; the printing head is a pneumatic gathering type microinjection spraying head which is controlled by a piezoelectric switch valve; the digital material 3D printing head is capable of forming the digital resin material on a forming part in a printing and forming process, so that the performance of the digital resin material is greatly coincident to the requirement of functional plastic members. Consequently, the performance of the similar products from board is achieved; meanwhile, the manufacturing cost is greatly reduced; the digital material 3D printing head is excellent in popularization and application prospects.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a digital material 3D printing head capable of printing digital resin materials. Background technique [0002] 3D printing is an advanced additive manufacturing technology. This technology is based on the discrete-stacking principle. It discretizes the 3D CAD model of the designed workpiece into a series of 2D cross-sectional thin layers from bottom to top, and then uses computer-controlled The 3D printer forms these cross-sectional thin layers layer by layer, and sequentially superimposes and bonds them into a three-dimensional workpiece entity. When using 3D printing technology to make workpieces, there is no need for traditional cutting machine tools and molds, and it can directly form three-dimensional entities with complex shapes, which can greatly save man-hours and costs, and is especially suitable for personalized production. Therefore, it is a modern key development ...

Problems solved by technology

However, there have been no reports on the development of digital resin materials and corresponding 3D printers and print heads in China, so they still need to be imported from abroad, and the price is very high, which is difficult for ordinary users to bear.
