Background

3D printing is a rapid prototyping technology, which is a technology for constructing objects by using powdery metal or plastic adhesive materials based on digital model files in a layer-by-layer printing mode. The 3D printing technology has emerged in the mid 90 s of the 20 th century, and is actually the latest rapid prototyping apparatus using techniques such as photocuring and paper lamination. The printing machine has the same basic working principle as that of common printing, and the printing machine is filled with liquid or powder and other printing materials, and after being connected with a computer, the printing materials are overlapped layer by layer under the control of the computer, so that a blueprint on the computer is finally changed into a real object.

At present, because various printed objects are different, the requirements on the spray heads of the printer are different, when different objects are subjected to printing operation, the spray heads are required to be replaced, the existing spray heads can be generally detached by using tools when being replaced, and when being detached, the spray heads are easy to fall down and break due to unstable placement. Thus, we provide a portable disassembly and assembly mechanism for a 3D printer head that solves the above problems.
