Abstract

The invention relates to multi-material 3D printing equipment based on electro-hydraulic-power coupling jet printing, and belongs to the technical field of 3D printing. The multi-material 3D printingequipment based on the electro-hydraulic-power coupling jet printing comprises a movable platform module, a workbench, a nozzle module, an injection pump module, a roller module and a control module;the material printed by the nozzle module can be a combination of various materials; the levelling of the liquid level of the printing material can be controlled by the roller module, and the thickness of each printing layer can be controlled through the combination of the movement of the roller module and the movement of the movable platform module; and the control module is used for controllingthe nozzle module, the movable platform and a relay contact to achieve the switching of the printing materials. According to the multi-material 3D printing equipment based on the electro-hydraulic-power coupling jet printing, printing of various materials can be realized, the switching speed of different printing materials is high, and the manufacturing cost of the nozzle module is low which is beneficial to reducing the cost of the whole machine.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a multi-material 3D printing device based on electro-hydraulic power coupled jet printing. Background technique [0002] 3D printing technology, also known as additive manufacturing technology, is a technology based on the principle of discrete stacking, through the gradual stacking of materials to achieve manufacturing. 3D printing technology uses slicing software to cut the 3D model of the part to be formed into a series of "thin slices" of a certain thickness. The 3D printing equipment manufactures each layer of "thin slices" from bottom to top, and finally superimposes to form a three-dimensional solid part. This manufacturing technology can realize the manufacture of complex structures that are difficult or impossible to process by traditional techniques, and can effectively simplify the production process and shorten the manufacturing cycle. According to different mold...

Problems solved by technology

The commercialized equipment that uses the combination of porous micro-spray nozzles and UV curing printing technology mainly includes Stratasys' Connex series printers and 3D Systems' Projet series printers. Among them, the porous micro-spray nozzles are the most critical part of multi-material 3D printers. The cost is expensive, which leads to the high cost of the whole machine of the 3D printer. The other two multi-material printing technologies are still in the experimental prototype stage. Their disadvantages are that a series of cleaning and drying processes are required when the solution tank is switched, and the Repositioning is required on the surface, resulting in long time required for material switching and low rate of workpiece forming
