Embodiment Construction

[0032] For ease of understanding, a brief introduction to traditional 3D printing equipment is given first.

[0033] Such as figure 1 As shown, a traditional 3D printing device 1 generally includes a feeding device 11 , a 3D printing head 12 , a printing platform 13 and a control device 14 .

[0034] The feeding device 11 can be connected to the wire tray 15 . In the actual printing process, the feeding device 11 can obtain filamentous materials from the wire tray 15, and transport the filamentous materials to the 3D printing head 12. The materials used in the 3D printing process are generally thermoplastic materials, such as polymer Polymers, low-melting-point metals, and other materials that can be made into fluid pastes (such as paste-like ceramics, high-melting-point metal powder mixtures, cement, etc.).

[0035] Such as figure 2 As shown, the 3D printing head 12 generally includes a material delivery pipe 121 , a material outlet 122 and a temperature control device 12...

Abstract

A 3D printing head (3), a 3D printing device (2) and a control method for the 3D printing head (3). The 3D printing head (3) includes: a feeding pipeline (31), the bottom (39) of the feeding pipeline (31) is provided with an opening (34); The bottom (39) is slidingly connected, and the opening (34) includes an area blocked by the shutter (32) and an area not blocked by the shutter (32), wherein the area not blocked by the shutter (32) forms the 3D printing head (3 ), the discharge port (35) includes a first end (351) and a second end (352), and the first end (351) and the second end (352) define the outlet The length of the feed opening (35); the driving device (33) is connected to the shutter (32), and the driving device (33) receives the control instruction of the control device (4), and drives the shutter ( 32) Sliding at the opening (34) to adjust the position of the first end (351) and / or the second end (352) in the opening (34), thereby adjusting the length of the outlet (35). The 3D printing head (3) makes it possible to balance printing efficiency and printing accuracy.

Description

technical field [0001] The present application relates to the field of 3D printing, and more specifically, to a 3D printing head, a 3D printing device, and a control method for the 3D printing head. Background technique [0002] Fused deposition modeling (FDM) technology is a commonly used 3D printing technology. FDM technology usually needs to heat the material to a molten state (or semi-fluid state), and extrude the molten material from the discharge port (or extrusion port) of the 3D printing head, and the material is deposited layer by layer on the printing platform to form 3D items. [0003] The outlet of a traditional 3D printing head is generally a nozzle with a fixed shape. When the printing accuracy of the item is required to be high, a 3D printing head with a smaller nozzle diameter is usually selected. This type of 3D printing head has less material extrusion per unit time and lower printing efficiency; when the printing efficiency of the item requires When it ...
