Embodiment Construction

[0017] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0018] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical", "horizontal", "left", "right", "top", "bottom", "bottom", "top" and similar expressions...

Abstract

The invention discloses a printing head applied to a fused deposition modeling (FDM) printer. The printing head comprises a screw type printing head body; the screw type printing head body comprises an extrusion shell and a spiral rod, wherein the spiral rod is arranged in the extrusion shell in an inserting way; the extrusion shell comprises a hollow cylinder part and a hollow frustum part; the spiral rod is inserted into the cylinder part of the extrusion shell, and the periphery of the spiral rod is closely connected with the inner wall of the extrusion shell; the interior of the spiral rodis a spiral groove from top to bottom; an included angle formed by the spiral groove and the horizontal direction is smaller than 10 degrees; the spiral rod is prepared from a material resisting thetemperature of 400 DEG C or above; the surface roughness of the spiral groove of the spiral rod is 3.2-25. The printing head applied to the FDM printer solves the problem that in the prior art, a printing head of the FDM printer leaks; the printing head provided by the invention has a spiral structure, thus solving the problem that the existing printing head of the FDM printer leaks when printinggranules, overcoming the defects that products printed by using the FDM printer and a 3D printer are rough in surface, have a wire-drawing phenomenon, and the like, and increasing the printing efficiency of the printers.

Description

technical field [0001] The invention relates to the technical field of 3D printing, and more specifically relates to a printing head applied to an FDM printer. Background technique [0002] Most of the print heads of FDM printers in the prior art are straight-hole type. When using this print head to print granular materials, there will be a problem affecting the appearance of the printed product, that is, there will still be materials from the printed area where there is no need to print. It flows out of the nozzle of the head and falls on the product being printed. The main reason is due to the self-weight of the material in the molten state, and the existing print head structure cannot solve the problem of affecting the printing appearance caused by the self-weight of the material. Contents of the invention [0003] The invention overcomes the problem of material leakage in the print head of the FDM printer in the prior art, provides a print head with a spiral structure...
