Embodiment Construction

[0027] For ease of understanding, a brief introduction to traditional 3D printing equipment is given first.

[0028] Such as figure 1 As shown, a traditional 3D printing device 1 usually includes a feeding device 11, a 3D printing head 12, a printing platform 13, and a control device 14 (the above structural division is only an example, in fact, other structural divisions can also be used, such as the control device And / or feeding device 11 may belong to a part of 3D printing head 12).

[0029] 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 pow...

Abstract

The invention provides equipment for 3D printing and a control method thereof. The equipment comprises a shell and an outlet assembly, wherein a material conveying channel is formed inside the shell;and the outlet assembly is arranged at one end of the material conveying channel, the outlet assembly comprises a first outlet piece and a second outlet piece which are complementary in a staggered mode and can slide relatively, a discharging opening is defined by being surrounded by staggered complementary structures of the first outlet piece and the second outlet piece, and the relative slidingbetween the first outlet piece and the second outlet piece can continuously change the length of the discharge opening. The discharging opening is designed to be the discharging opening with the continuously adjustable length so that the 3D printing efficiency and precision can be possibly considered at the same time.

Description

technical field [0001] The present application relates to the field of 3D printing, and more specifically, relates to a device for 3D printing and a control method thereof. 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 nozzle with a smaller diameter is usually selected. This type of nozzle has less material extrusion per unit time and the printing efficiency is lower; when the printing efficiency of the item is required to be higher, usually A nozzle with a larger diamet...
