A kind of 3D printer
This utility model relates to printer technology field, is specially a kind of 3D printer.
3D printer is the one of printer, and it uses 3 D-printing (3D printing), i.e. Rapid Prototyping technique, it
Based on being a kind of mathematical model file, use powdery metal or plastics etc. can jointing material, by the way of successively printing
Carry out the technology of constructed object.Past its be often used for modeling in the field such as Making mold, industrial design, be now increasingly used for
Directly manufacturing of some products.
Existing 3D printer is typically merely able to carry out the file printing of a kind of color, if desired during many color print, although
Multiple shower nozzle can be used, but, during the work of many shower nozzles 3D printer, it is necessary to multiple shower nozzles are carried out different colours material
Switching can realize colour mixture and print, and different colours material correspondence difference shower nozzle, switching process is loaded down with trivial details, and printing effect is relatively low.
Utility model content
The purpose of this utility model is to provide a kind of 3D printer, possesses and only needs a shower nozzle can enter multiple color
Row prints, the more convenient advantage of switching to print colors, solves existing 3D printer needs when printing different colours
Switching over multiple shower nozzles, switching process is loaded down with trivial details, the problem that printing effect is relatively low.
For achieving the above object, this utility model following technical scheme of offer: a kind of 3D printer, including D printer originally
Body, the internally installed of described D printer body has sub butt ends, and the screw top of sub butt ends connects cover plate, described sub butt ends
Inside offers remittance material chamber, and the upper surface of sub butt ends is around offering sub-material chamber, and the bottom in each sub-material chamber is all expected with converging
Chamber connects, and each sub-material intracavity is provided with block, and the top of block is provided with connecting tube, and the bottom thread of described sub butt ends is even
Being connected to expect, with converging, the shower nozzle that chamber connects, the side surface of sub butt ends offers the charging aperture of connection corresponding with sub-material chamber.
The equidistant through hole that offers in outside of described cover plate upper surface, is provided with feed pipe, feed pipe in each through hole
Bottom corresponding with charging aperture connect, threaded on described cover plate have screw rod, and screw rod is arranged with lid, described lid and company
The screw top of adapter connects, and the bottom of screw rod is welded with spacing disk, and spacing disk is positioned at the inside of connecting tube.
Preferably, described block be coated with rubber sealing boot, and the two sides of block are provided with slide block, institute
State the slide that block offered with sub-material intracavity side by slide block to be connected.
Preferably, the quantity in described sub-material chamber is no less than four, and the equidistant cincture in sub-material chamber no less than four sets
Put in the outside converging material chamber.
Preferably, described cover plate is disc-shaped structure, and the diameter of cover plate is more than the diameter of sub butt ends.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, this utility model arranges single shower nozzle and prints multiple color, thus decreases the installation quantity of shower nozzle,
Save cost, decreased the trouble switched between multiple shower nozzle, improve printing effect.
2, this utility model utilizes the cooperation of screw rod, sub butt ends and block to switch over printing raw material, switches the most square
Just, it is capable of multiple printing raw material simultaneously and carries out mixing printing, regulate more convenient, the setting of rubber sealing boot, it is possible to protect
Sealing between card block and sub-material chamber, the raising that coordinates of slide block and chute makes the location of block the most accurate.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-6, a kind of 3D printer, including 3D printer body 12,3D printer body 12 internally installed
Having sub butt ends 1, it is disc-shaped structure that the screw top connection of sub butt ends 1 has cover plate 4, cover plate 4, and the diameter of cover plate 4 is more than sub-material
The diameter of 1, the inside of sub butt ends 1 offers remittance material chamber 9, and the upper surface of sub butt ends 1 is around offering sub-material chamber 10, and often
With converging, the bottom in individual sub-material chamber 10 all expects that chamber 9 connects, the quantity in sub-material chamber 10 is no less than four, and the sub-material no less than four
The equidistant outside being circumferentially positioned at remittance material chamber 9, chamber 10, is provided with block 8 in each sub-material chamber 10, utilizes screw rod 6, sub-material
1 and the cooperation of block 8 switch over printing raw material, switch more convenient, be capable of multiple printing raw material simultaneously and carry out
Mixing print, regulate more convenient, block 8 be coated with rubber sealing boot 14, the setting of rubber sealing boot 14, it is possible to protect
Sealing between card block 8 and sub-material chamber 10, and the two sides of block 8 are provided with slide block 13, block 8 by slide block 13 with
