Nozzle quick changing system for 3D printing machine and printing machine

Abstract

The invention discloses a nozzle quick changing system for a 3D printing machine and the printing machine with the nozzle quick changing system. The nozzle quick changing system comprises a nozzle magazine fixed to a printing platform, and a motion mechanism grabbing module fixed to a motion mechanism of the 3D printing machine, wherein at least two required nozzle modules are fixed to the nozzle magazine; and the motion mechanism grabbing module grabs and places the corresponding nozzle module according to an instruction. The innovation point of the nozzle quick changing system is that the nozzle quick changing system for the 3D printing machine is designed through a modular design concept, so that the common 3D printing machine equipped with the system has the capacity of changing the nozzle for printing; the nozzle modules of different printing types can be automatically changed during the printing process, so that the 3D printing machine can print 3D printing pieces made of multiple mixed materials, and the printed printing pieces have special performance; and modular design is adopted, so that all the developed nozzle modules with a connecting assembly can be utilized in the nozzle quick changing system.

Description

technical field [0001] The invention belongs to the field of 3D printing equipment, and in particular relates to a nozzle quick-change system that can be installed on a 3D printer as an accessory and a printer with the system. Background technique [0002] 3D printing technology is also called rapid prototyping technology or additive manufacturing. Compared with the traditional manufacturing process of removing materials, the 3D printing process uses the principle of layer-by-layer superposition of materials to generate a complete part. As one of the research hotspots in the field of advanced manufacturing in recent years, 3D printing technology has been widely used in manufacturing, aerospace, national defense, biomedical, food chemistry and other fields. The use of 3D printing technology can shorten the product development cycle, quickly obtain product prototypes and speed up the accuracy of product iteration upgrades, and some complex geometric shapes that are difficult t...

Problems solved by technology

[0003] However, as 3D printing technology is applied in more and more fields, general single-nozzle 3D printers can no longer meet the needs of multi-material printing.

There are also some 3D printers with multiple nozzles, but the range of printable materials is small and the expansion ability is poor
