Multi-spraying-head 3D printer

Abstract

The invention discloses a multi-spraying-head 3D printer. The printer comprises a printing platform lifting device, a double-tooth-belt horizontal moving device, a material box, a multi-spraying-headmount and a printer frame; the printing platform lifting device is mounted on the printer frame, and connected with the double-tooth-belt horizontal moving device, and the double-tooth-belt horizontalmoving device is connected with the multi-spraying-head mount; and the material box is mounted on the printer frame, and connected with the multi-spraying-head mount through material supply pipes. The multi-spraying-head 3D printer has the advantages that moving strategies in the X, Y and Z directions are provided by adopting the mode that a servo motor is connected with tooth belts; spraying heads can be automatically switched in the whole printing process by adopting the design that the multiple spraying heads are arranged on a spraying head fixing disc, and thus the production efficiency is improved; and the design demand is ensured, the structure is simple, the number of the spraying heads can be deployed according to practical needs, the spraying heads are mounted rapidly, errors areavoided, and the printing quality is ensured.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a multi-nozzle 3D printer. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. Use 3D printers to quickly manufacture your own design, improved parts or other novel works at low cost, which greatly releases the imagination of designers. At present, most 3D printers have a single nozzle, and manual replacement of nozzles is required during the printing process, which is complicated to operate and low in efficiency. At the same time, problems such as height adjustment errors may occur after replacement. However, dual / multi-nozzle 3D printers commonly used in the market are The rubbing problem is easy to occur during printing, which affects the quality of the workpiece. In order to avoid ...

AI Technical Summary

Problems solved by technology

At present, most 3D printers have a single nozzle, and manual replacement of the nozzle is required during the printing process. The operation is complicated and the efficiency is low. At the same time, problems such as height adjustment errors may occur after replacement. However, the dual / multi-nozzle 3D printers commonly used in the market are The rubbing problem is prone to occur during printing, which affects the quality of the workpiece. In order to avoid this problem, the printing size of the workpiece has to be reduced. Moreover, the dual / multi-nozzle 3D printers on the market generally only print support materials and finished materials, which are difficult to meet the assembly requirements. product design requirements
