Problems solved by technology

[0004] 3D printing head is an important component of 3D printing equipment. The current 3D printing head has a single function and can only print out solid structures. If all structures are printed into solid structures, it will inevitably cause some unnecessary waste, and In order to save material, people hope to print hollow structures in some cases

Embodiment Construction

[0016] The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations.

[0017] Such as Figure 1-3 The print head of a 3D printer shown includes a first barrel 2, a first discharge needle 6 arranged at the lower end of the first barrel 2 and a first feed tube 3 arranged at the upper end of the first barrel 2, The first barrel 2 and the first discharge needle 6 are coaxially arranged, the first discharge needle 6 is conical, and the molten metal material enters the first barrel 2 from the first feed pipe 3 and Flow out from the first discharge needle 6 to realize 3D printing.

[0018] A partition plate 5 extending axially is arranged in the first barrel 2, and both sides of the partition plate 5 are at least fixedly connected with the inner wall of the first discharge needle 6,...

Abstract

The invention discloses a printing head of a 3D printer. A first material barrel and a first discharging needle head coaxially arranged at the lower end of the first material barrel are included. An axial-extending partition plate is arranged in the first material barrel, and the two sides, in the width direction, of the partition plate are at least fixedly connected with the inner wall of the first discharging needle head. The lower end of the partition plate is at least aligned with the lower end of the first discharging needle head. A second material barrel arranged on the outer side of thefirst material barrel and a second discharging needle head coaxially arranged at the lower end of the second material barrel are further included. The second material barrel and the first material barrel are coaxially arranged, and the lower end of the second discharging needle head is lower than the lower end of the first discharging needle head. The printing head can achieve solid printing andcan also achieve hollow printing.

Description

[0001] This application is a divisional application with the application number 2017104307309, the application date of June 9, 2017, and the title of the invention "a print head for a 3D printer". technical field [0002] The invention relates to the field of 3D printing, in particular to a printing head of a 3D printer. Background technique [0003] 3D printing (three-dimensional printing) is a kind of rapid prototyping technology. It is based on a digital model file, using plastic and other materials, extruded through a nozzle with a fine nozzle, and starts to solidify after the temperature is lower than the curing temperature. , through the accumulation of layers of plastic materials to finally form a finished product, and the technology of constructing objects by layer-by-layer printing. [0004] 3D printing head is an important component of 3D printing equipment. The current 3D printing head has a single function and can only print out solid structures. If all structure...
