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.

Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0020] Such as Figure 1-Figure 4 As shown, this embodiment includes a heating head 21 and a wire feeding mechanism 20. The heating head 21 includes 8 sub-heating heads 1, connecting plates 6, front and rear fixed baffles 2 and left and right fixed baffles 4. The sub-heating heads 1 Arranged in a matrix on the connecting plate 6 to form an integrated 3D printer nozzle, the advantage of the matrix arrangement is that the mutual positions of the nozzles are stable, and the movement of the motors in the X and Y directions can be well compensated. The movement error of the heating head in the XY plane.

[0021] The feed port of the sub-heating head 1 is connected to the feed port of the wire feeding mechanism 20 at the far end through a sleeve 19 .

[0022] Another example figure 2 As shown, the sub-heating head 1 is provided with a sensor fix...

Abstract

The invention relates to three-dimensional printing technology, in particular to a printing head of a three-dimensional printer. It includes a heating head and a wire feeding mechanism, and is characterized in that the heating head includes more than two sub-heating heads, connecting plates, front and rear fixed baffles, and left and right fixed baffles, and the sub-heating heads are arranged in a matrix on the On the connecting plate, the feed port of the sub-heating head is connected to the feed port of the wire feeding mechanism at the far end through a sleeve. Its purpose is to design a print head of a three-dimensional printer that can complete multi-color printing and can effectively improve printing accuracy and speed. Compared with the prior art, it has the advantages of compact structure, small volume, light weight, small working load, and adjustable wire compression degree.

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...
