One-time multi-material 3D printing mechanism based on mechanical arm

Abstract

The invention belongs to the field of 3D printing, and specifically discloses a one-time multi-material 3D printing mechanism based on a mechanical arm. The one-time multi-material 3D printing mechanism comprises a data processing system, a control system, a dynamical system, a mechanical arm and an extrusion system, wherein the data processing system is used for presetting a printing path according to material characteristics; the control system is used for controlling the extrusion system to print according to the preset printing path by virtue of the dynamical system and the mechanical arm;the extrusion system comprises a multi-nozzle assembly, the multi-nozzle assembly is installed on the tail end of the mechanical arm and comprises a plurality of mutually independent single-nozzle units, each single-nozzle unit comprises a printing nozzle and a storage hopper which are connected with each other, and the diameters of the printing nozzles are varied. According to the one-time multi-material 3D printing mechanism, modeling software is combined with the mechanical arm, and additionally, the multi-nozzle assembly is designed, so that the extrusion speed of multiple nozzles with different diameters is adjusted on the basis of a one-time fixed moving speed, and the printing precision and the printing speed are increased.

Description

technical field [0001] The invention belongs to the field of 3D printing, and more specifically relates to a single-time multi-material 3D printing mechanism based on a mechanical arm. Background technique [0002] 3D printing is an emerging manufacturing technology based on a digital model that accumulates materials layer by layer to produce physical objects. It will have a profound impact on the traditional process flow, production line, factory model, and industrial chain combination. It is a representative subversion of the manufacturing industry. 3D printing technology has been widely used in industrial machinery, aerospace and other industries. 3D concrete printing technology is still immature and far from reaching the stage where it can be fully promoted. In the field of construction, due to factors such as material and size, common extrusion 3D printers only include a single nozzle and print one material at a time, which has problems such as slow printing speed and ...

3D concrete printing technology is still immature and far from reaching the stage where it can be fully promoted

[0007] However, none of the above methods can perform 3D printing of multiple building materials at the same time, and there are problems of slow printing speed, low efficiency, and poor effect. Therefore, there is an urgent need for a multi-nozzle 3D printing mechanism and method that can print multiple materials at a time.
