A little occasions for needing to save material, and disclosure satisfy that some need the requirement of higher-strength by solid printing, and then can be real
The demand of existing different occasions, convenient use；
2) the first barrel of the printhead realizes hollow printing using demarcation strip, according to demarcation strip in the first barrel
Diverse location can print the two side of different-thickness；And the both sides of demarcation strip are respectively arranged with a feed pipe, by right
Two feed pipes are respectively controlled, and can also print different structures.
Brief description of the drawings
Fig. 1 is sectional view according to a preferred embodiment of the present invention
Fig. 2 is the schematic diagram of demarcation strip according to a preferred embodiment of the present invention
Fig. 3 is the schematic diagram according to the demarcation strip of a preferred embodiment of invention and the cooperation of the first barrel
Embodiment
Describe to be used to disclose the present invention below so that those skilled in the art can realize the present invention.It is excellent in describing below
Embodiment is selected to be only used as citing, it may occur to persons skilled in the art that other obvious modifications.
A kind of printhead of 3D printer as Figure 1-3, including the first barrel 2, it is arranged on the lower end of the first barrel 2
First discharging syringe needle 6 and the first feed pipe 3 for being arranged on the upper end of the first barrel 2, the discharging syringe needle 6 of the first barrel 2 and first
It is coaxially disposed, the first discharging syringe needle 6 is tapered, and the metal material of thawing is entered in the first barrel 2 from the first feed pipe 3
And flowed out from the first discharging syringe needle 6 and then realize 3D printing.
The demarcation strip 5 axially extended is provided with the first barrel 2, the both sides of the demarcation strip 5 at least go out with first
The inwall of material pin first 6 is fixedly connected, and the lower end of the demarcation strip 5 is at least alignd with the first lower end for discharging syringe needle 6, can also be omited
Micro stretching goes out the first discharging syringe needle 6.The upper end of the demarcation strip 5 can be extend into the first barrel 2, and ought extend into the first material
When in cylinder 2, the both sides of the demarcation strip 5 are fixedly connected to increase the fastness of demarcation strip 5 with the inwall of the first barrel 2.Pass through
The metal flowed out from the first discharging syringe needle 6 can be divided into twice by demarcation strip, and the middle part of twice does not have metal, that is, in realizing
Sky printing.
Further, the metal flow of the both sides of demarcation strip 5 is controlled for convenience, and the upper end of the demarcation strip 5 is entered higher than first
Topmost, the side relative with the first feed pipe 3 is provided with the 3rd feed pipe 31, and then realization pair to expects pipe 3 on the first barrel 2
The metal flow of the both sides of demarcation strip 5 in first barrel 2 is respectively controlled.
Further, the demarcation strip 5 can be located on the axis of the first discharging syringe needle 6, the knot for the both sides now printed
Structure width is identical, and on the axis that can not also be located at the first discharging syringe needle 6, the structure width for the both sides now printed is different.
The printhead also includes the second barrel 11 being coaxially disposed with the first barrel 2, the lower end of second barrel 11
The second discharging syringe needle 12 being coaxial therewith is provided with, the second discharging syringe needle 12 is tapered.The first discharging syringe needle 6 is set
It is less than the lower end of the first discharging syringe needle 6 in the lower end of the inner side of the second discharging syringe needle 12, and the second discharging syringe needle 12, and is less than
The lower end of demarcation strip 5 can be beaten with will not be separated when ensureing that the lower end for melting metal from the second discharging syringe needle 12 is flowed out
Print off solid structure.The second feed pipe 10 is provided with the upside of second barrel 11, melts metal from the second feed pipe
10 enter in the second barrel 11 and are flowed out from the lower end of the second discharging syringe needle 12.
Fix for convenience, the upper end of the first barrel 2 is higher than the upper end of the second barrel 11, and the first feed pipe 3 and the
