Multi-color integrally-forming 3D printer

Abstract

The invention discloses a multi-color integrally-forming 3D printer. The multi-color integrally-forming 3D printer mainly comprises a printer frame, a raw material frame, sprayer material supply modules and a gripper mechanism; the raw material frame is fixed to the printer frame; the sprayer material supply modules are clamped on the material frame; the top gripper mechanism can slide freely in the horizontal direction and the vertical direction through a guide rail; and the gripper mechanism is used for grabbing different sprayer material supply modules. Each sprayer material supply module consists of a raw material, a thread clamping device, a telescopic device, a heating device, a thread reeling device and a nozzle. The printer disclosed by the invention is not provided with a thread conveying module of a previous 3D printer; the raw material moves with the movement of the nozzle; the thread reeling device is used for reeling threads into the heating device and the threads are extruded out of a sprayer. The 3D printer has obvious advantages, can be used for printing multi-color products, is clean, tidy and not messy in overall structure, prevents the current situation that thethreads are intertwined and are easy to break in a multi-color printing process, and reduces the error rate in a product printing process.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a multi-color integrated 3D printer. Background technique [0002] At present, there are many kinds of non-metallic printers, and the manufacturing cost of different equipment varies according to the printing materials. The production cost of photo-curing molding method and laser sintering method equipment is high, and the material cost is also high. Compared with the commonly used ABS material and PLA material price Cheap, low equipment production cost and widely used, but the printed product has a single color, rough surface, and wire jams and broken wires often occur during the printing process. At present, the existing multi-color printers on the market are basically dual-nozzle printers, which can print two colors at the same time. However, in the actual use of the double-nozzles, there are scratches. There are still many problems in order to truly realize multi-color pr...

[0002] At present, there are many kinds of non-metallic printers, and the manufacturing cost of different equipment varies according to the printing materials. The production cost of photo-curing molding method and laser sintering method equipment is high, and the material cost is also high. Compared with the commonly used ABS material and PLA material price Cheap, low equipment production cost and widely used, but the printed product has a single color, rough surface, and wire jams and broken wires often occur during the printing process

At present, the existing multi-color printers on the market are basically dual-nozzle printers, which can print two colors at the same time. However, in the actual use of the double-nozzles, there are scratches. There are still many problems in order to truly realize multi-color printing. need to overcome
