Embodiment Construction

[0029] For ease of understanding, a brief introduction to traditional 3D printing equipment is given first.

[0030] 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).

[0031] 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

Provided are a device for 3D printing and a control method thereof. The device includes: a housing, the inner surface of which forms a cylindrical inner cavity, and an opening extending along the axial direction of the cylindrical inner cavity is arranged on the housing; In the cylindrical inner cavity, the area in the opening is covered, and the area in the opening that is not blocked by the blocking part forms a discharge port. The rotating shaft can rotate around the axis of the cylindrical inner cavity to continuously change the blocking part to block the opening. area, so as to continuously change the length of the discharge port; the feed port communicates with the material delivery channel surrounded by the outer end surface of the shielding part and the inner surface of the housing. Designing the discharge port as a continuously adjustable discharge port can make it possible to balance the efficiency and precision of 3D printing.

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...
