Problems solved by technology

[0003] At present, the three-dimensional printing method (3DP) 3D printer on the market sprays the adhesive from the print head to make the powder select area bonded and formed. Using the above method, there are mainly the following disadvantages: 1. The residual adhesive on the surface of the print head is easy to solidify and block the printer Print nozzles; thereby affecting the use of 3D printers; 2. Shorten the life of printer nozzles
Therefore, in 3D printing technology, the cleaning of the print head is very important. It not only affects the life of the printer, but also affects the printing quality of the printer and affects the customer experience.

Embodiment Construction

[0018] refer to figure 1 , the present invention proposes a 3D printer for preventing powder clogging nozzles, comprising: an air pump 1 , a first butt joint 2 , a second butt joint 3 and a recovery box 4 .

[0019] The end of the nozzle A of the printer away from the nozzle is provided with a backflush conduit 5, and the backflush conduit 5 is provided with a cut-off valve 6 to prevent the printer nozzle A from leaking through the backflush conduit 5 during normal operation.

[0020] One end of the first pair of joints 2 is connected to the output end of the air pump 1, and the other end is adapted to the outlet of the nozzle A of the printer. One end of the second pair of connectors 3 is connected to the input port of the recovery box 4 , and the other end is adapted to the backwash conduit 5 .

[0021] In this embodiment, the end where the nozzle A of the printer is located is provided with an external thread, and the first pair of joints 2 is provided with an internal thr...

Abstract

The invention discloses a 3D printer capable of preventing powder from blocking a spray head. The 3D printer comprises an air pump, a first butt connector, a second butt connector and a recycling box. The end, away from a spray outlet, of the spray head of the printer is provided with a thrust guide pipe, the thrust guide pipe is provided with a cut-off valve, one end of the first butt connector is connected with the output end of the air pump, the other end of the first butt connector is matched with the spray outlet of the spray head of the printer, one end of the second butt connector is connected with an input port of the recycling box, and the other end of the second butt connector is matched with the thrust guide pipe. The spray head of the printer is washed through airflow, the washing effect can be ensured, powder residue is avoided, and the spray head of the printer is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printer capable of preventing powder from clogging nozzles. Background technique [0002] 3D printing technology is different from the traditional mechanical processing of "subtractive molding", but the "additive molding" process of layered processing. Although 3D printing technology still has problems, it has a variety of technologies and is close to maturity. The basic part of a 3D printer is that the printing head sprays the printing material onto the printing workpiece of the printing platform, or it is formed by selectively solidifying and fusing the powder layer by layer; and the relative 3D (3D) sports. [0003] At present, the three-dimensional printing method (3DP) 3D printer on the market sprays the adhesive from the print head to make the powder select area bonded and formed. Using the above method, there are mainly the following disadvantages: 1. The residua...
