Problems solved by technology

Therefore, if the nozzles are directly arranged in parallel and printed at the same time, the printed filaments are limited by the diameter of the filament and the constraints of the nozzle structure, so that the distance between the extruded materials will be very wide.
Another example is printing food (such as chocolate), glue, concrete, electrolyte, etc., the diameter of the nozzle is often not made very thin, even if the distance between the nozzles is made close enough, it often does not have good reliability and strength. , durability, etc., even if it cannot be directly applied, it has no practical value

Embodiment 1

[0107] see figure 1 As shown, a cross-sectional view of a multi-nozzle 3D printing nozzle, this embodiment specifically provides a printing nozzle, including a nozzle seat A, a nozzle seat B, and a driving device D. Wherein, at least two nozzles are arranged on the printing nozzle, the nozzle seat B is movably arranged on the nozzle seat A, and at least one nozzle N is arranged on the nozzle seat B. See figure 1 As shown, two nozzles N01 and N02 are set on the nozzle seat B; see figure 2 As shown, two nozzles N01 and N02 are set on the nozzle seat B, and one nozzle NA is set on the nozzle seat A. When in use, the driving device D drives the nozzle seat B to move, and the printing nozzle drives the two nozzles N01 and N02 to move along the set printing path and complete printing.

[0108] It should be noted that in figure 1 The middle nozzle seat B is slidingly sleeved on the inner side of the nozzle seat A, and preferably the midpoint of the line connecting the two noz...

Embodiment 2

[0112] The structure and working principle of the second embodiment and the first embodiment are basically the same, see Figure 5 As shown, the only difference is that the nozzle seat includes the first nozzle seat B1, the second nozzle seat B2 and the third nozzle seat B3, and at least one first nozzle N1 is set on the first nozzle seat B1, and the second nozzle seat At least one second nozzle N2 is arranged on B2, and at least one third nozzle N3 is arranged on the third nozzle seat B3. Meanwhile, the driving device D includes a first driving device D1 , a second driving device D2 , and a third driving device D3 . Wherein, the first nozzle seat B1 is connected to the first driving device D1 and is driven to move by the first driving device D1; the second nozzle seat B2 is connected to the second driving device D2 and is driven to move by the second driving device D2; The third nozzle seat B3 is connected with the third driving device D3, and is driven to move by the third ...

Embodiment 3

[0121] The structure and working principle of the third embodiment are basically the same as those of the second embodiment, and the first nozzle seat B1, the second nozzle seat B2 and the third nozzle seat B3 are arranged concentrically along the same central axis. see Figure 8 As shown, the only difference is that the third driving device D3 is arranged on the nozzle seat A, the second driving device D2 is fixed on the third nozzle seat B3, and the first driving device D1 is fixed on the second nozzle seat B2. In this way, the third nozzle seat B3 can be driven to rotate relative to the nozzle seat A through the third driving device D3, and at the same time, the second driving device D2 connected to the third nozzle seat B3 can drive the second nozzle seat B2 to rotate, and the second nozzle seat B2 can be rotated with the second nozzle The first drive device D1 connected to the seat B2 drives the first nozzle seat B1 to rotate, thereby realizing the one-way linkage functio...

Abstract

The invention discloses a multi-nozzle 3D spray-head, a printing method and a 3D printer. According to the method, a spray-head and a printing platform are adopted for printing, a plurality of nozzles are arranged on the spray-head, the spray-head comprises a spray-head seat and nozzle seats, the spray-head carries out 3D printing on the printing platform, the nozzles carry out relative motions in the x, y, z directions on the printing platform, and through the rotation of the nozzle seats or the spray-head seat relative to the printing platform respectively, at least two nozzles are enabled to move along corresponding printing paths respectively. By adopting the method provided by the invention for printing, the printing efficiency of the printer can be effectively improved, not only the printing of a printing path with small curve radius is facilitated, but also the rotational angles of the nozzle seats are reduced, the speed of the multiply nozzles following various curvature printing paths is increased, the load of a nozzle seat driving device or a driving device for the rotation of the printing platform is reduced, and various requirements in actual application are met.

Description

technical field [0001] The present invention relates to the technical field of 3D printers, in particular to a multi-nozzle 3D printing nozzle and a printing method, and a 3D printer using the multi-nozzle 3D printing nozzle or the printing method. Background technique [0002] The existing FDM (abbreviation of "Fused Deposition Modeling", fused deposition modeling) 3D printer is through the x, y, z between the nozzle and the platform, three linear unrelated movements (that is, three independent movements direction), so that the nozzle can reach any position within a certain area above the platform. At the same time, the nozzle on the nozzle seat extrudes the material to the appropriate position of the model on the platform at an appropriate speed. After completing the printing of one layer, it continues to print on the next layer, and stacks layer by layer to form a three-dimensional entity. [0003] The existing numerical control jet electroforming, or numerical control s...
