Abstract

The invention discloses a double-sprayer and dual-mode 3D printer and an operation method thereof, and belongs to the technical field of 3D printing equipment. The printer comprises a bracket, a bottom platform device, a printed material fixing device, a driving motor I, a sprayer I, a sprayer II, a driving motor II and a central control unit, wherein the sprayer II is provide with two nozzles, and the two nozzles are respectively loaded with liquid A and liquid B in PU resin AB adhesive. The printer adopts a technology for constructing an object by replacing the mode of printing layer by layer through a mode of printing a casing and spraying the filler (PU resin AB adhesive), ensures that the strength of parts is improved, and reduces the part scrapping ratio. The weight mixing ratio of the liquid A to the liquid B in the PU resin AB adhesive is 1:1, as the liquid A and the liquid B can be cured in 1.5 to 2 minutes after being mixed, the curing speed is high, and the purpose of saving printing time is achieved. The printer adds new structure improvement design on traditional 3D printer equipment, and is low in improvement machining cost, and good in inheritability of manufacturing process and technical process.

Description

technical field [0001] The invention belongs to the technical field of 3D printing equipment, and in particular relates to a device for 3D printing parts and a working method thereof. Background technique [0002] At present, ordinary 3D printers are based on digital model files (mainly including stl and AMF files), layering the digital model, using powdered metal or plastic and other bondable materials, and printing layer by layer. A device for constructing objects in a manner. [0003] 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and later it is gradually used in the direct manufacture of some products. At present, there are already parts printed using this technology. The technology has numerous applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries,...
