Embodiment Construction

[0051] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated.

[0052] Refer below Figure 1-Figure 5 A powder-spreading 3D printer according to the present application is described. Such as Figure 1-Figure 5 As shown, a powder spreading type 3D printer 1 includes: a printer body and a liquid spraying device. The liquid spraying device includes a fluid bucket 100, a nozzle frame 200 and a nozzle 300. The nozzle frame 200 is slidably installed on the printer body, and the nozzle 300 is installed on the On the spray head frame 200, an overflow channel is formed in the spray head 300. The overflow channel has an inlet and an outlet. When the flow passage moves to the first target position, the inlet and the outlet are connected, a...

Abstract

The invention provides a powder spreading type 3D printer, which comprises a printer main body and a liquid spraying device, wherein the liquid spraying device comprises a fluid barrel, a spraying head frame and a spraying head, the spraying head frame is slidably arranged on the printer main body, the spraying head is arranged on the spraying head frame, a flow passing channel is formed in the spraying head, and has an inlet and an outlet, the inlet is communicated to the fluid barrel, the outlet position is provided with a spraying nozzle, a blocking member is movably arranged in the flow passing channel, the blocking member communicates the inlet and the outlet when the blocking member moves to a first target position relative to the flow passing channel, the flow passing channel disconnects the inlet and the outlet when the blocking member moves to a second target position relative to the flow passing channel, one side, away from the inlet, of the blocking member is provided with an elastic member, and the elastic member is used for bearing against the blocking member so as to make the blocking member move from the first target position to the second target position. Accordingto the present invention, by using the powder spreading type 3D printer, the outflow amount of the fluid can be precisely controlled, such that the precision of the liquid spraying during the powder spreading is achieved so as to improve the printing precision of the printer.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a powder spreading type 3D printer. Background technique [0002] With the rapid development of 3D printing technology, 3D printers can already print a variety of printing materials such as rock-like materials to meet applications in different fields. At present, rock-like materials can be printed by powder-spreading 3D printers to conduct simulation experiments on the printed 3D models. The spraying accuracy of the liquid spraying device in the powder-spreading 3D printer has a great influence on the accuracy of the printed 3D model. Therefore, in the prior art, the liquid spraying device is usually improved to improve the printing performance of the powder-spreading 3D printer. precision. [0003] In the prior art, the spraying device of the powder-spreading 3D printer includes a nozzle, a fluid delivery pipe, a pump and a fluid barrel, and an overflow channel is formed i...
