3D printer based on CPVC/PVC gel material

Abstract

The invention relates to a 3D printer based on a CPVC / PVC gel material which comprises a printing box body, a feeding device, a portal frame device, a printing platform, a heating device and an air purification device. The feeding device, the portal frame device and the printing platform are fixedly installed in the printing box body; the air purification device is fixedly installed on the side wall of the printing box body; the feeding device comprises a bottom plate and feeding mechanisms; the at least two feeding mechanisms are installed on the bottom plate; each feeding mechanism comprises a pushing assembly, a needle cylinder and a needle cylinder clamp; the pushing assemblies and the needle cylinder clamps are installed on the bottom plate; the needle cylinders are installed in the needle cylinder clamps; the pushing assemblies are matched with the needle cylinders and drive the needle cylinders to conduct feeding; and the multiple feeding mechanisms are arranged in the printer, so that printing can be conveniently conducted through various materials; and different materials such as a gel layer and an electrode layer can be switched to be printed, so that integrated forming is achieved. The heating device can enable the printed gel layer or electrode layer to be rapidly formed, so that the printing efficiency is improved. A sealing and air purifying module is arranged, so that the discharged gas is free of peculiar smell, the internal printing process is free of leakage, and the influence of the printer on the external environment in the working process is reduced to the minimum.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, and in particular relates to a 3D printer based on CPVC / PVC gel material. Background technique [0002] Traditional 3D printing methods include extrusion fused deposition molding, granular material molding, and photopolymerization molding. Extrusion fused deposition molding is to melt the filamentous hot-melt material and pass it through the nozzle with a fine nozzle, spray and deposit it on the workbench or the previous layer of solidified material, and start to solidify when the temperature drops to the solidification temperature; granular Material molding is to sinter and smelt powdery materials by laser, electron beam, etc. to perform 3D printing; light-curing 3D printing is based on the photopolymerization principle of liquid photosensitive resin, and laser beams are used to irradiate the surface of liquid photosensitive resin to make the surface specific. After the resin layer in the a...
