Printing head of three-dimensional printer

Abstract

The invention relates to a three-dimensional printing technology, and particularly relates to a printing head of a three-dimensional printer. The printing head comprises a heating head and a wire feeding mechanism, and is characterized in that the heating head comprises more than two sub heating heads, a connecting plate, a front fixed baffle plate, a rear fixed baffle plate, a left fixed baffle plate and a right fixed baffle plate, the sub heating heads are arranged on the connecting plate according to a matrix, and a feeding hole of each sub heating head is connected with a discharging hole of the wire feeding mechanism at the far end through a sleeve. The printing head of the three-dimensional printer is capable of completing multicolor printing and capable of effectively improving the printing precision and increasing the printing speed. Compared with the prior art, the printing head has the advantages of compact structure, small size, light weight, small working load, adjustable compaction degree of a wire rod, and the like.

Description

technical field [0001] The invention relates to three-dimensional printing technology, in particular to a printing head of a three-dimensional printer. Background technique [0002] Three-dimensional printing technology is one of the rapid prototyping technologies with the most development potential at present, and it is suitable for the development of new products in the fields of mechanical engineering, electronic engineering, and biomedicine. As an economical rapid prototyping technology, it has the advantages of low cost, high system reliability, small equipment size, low noise, fast forming speed, etc. It has huge application potential and broad market prospects. The 3D printers currently on the market are generally monochrome printing, and the models that can be printed have a single color; however, machines that can complete multi-color printing are relatively expensive, which is not conducive to widespread use in a wide range. The print head of traditional 3D printe...

Problems solved by technology

The 3D printers currently on the market are generally monochrome printing, and the models that can be printed have a single color; however, machines that can complete multi-color printing are relatively expensive, which is not conducive to widespread use in a wide range

The print head of the traditional 3D printer adopts the proximal wire feeding method, and its wire feeding mechanism (including the wire feeding motor) is connected with the nozzle. This type of design will cause a large load on the system during the printing process, which will affect the printing speed and accuracy.
