Problems solved by technology

However, every time a "support" is printed, more materials and printing time will be consumed, and the carrying capacity of the "support" is also limited (to ensure that the "support" is easy to separate and remove), if the support is high and large, it is easy to cause Partial collapse or even damage of the product
However, the current 3D printing equipment is still lacking in terms of saving "support" volume and quantity, improving printing efficiency and printing process stability, etc.

Embodiment 1

[0034] Embodiment 1: as Figure 1 to Figure 10 In the shown embodiment, a 3D printing device includes a main frame 1, a discharge printing head 2, a forming printing table 3, and also includes a printing head for driving the discharge printing head to move so as to change the position of the discharge printing head Displacement adjustment mechanism, the said discharge print head is provided with a print head feed end for inputting printing materials, said discharge print head is provided with a discharge channel 21 communicating with the print head feed end, said forming printing The stage includes a fixed platen 31 , at least one movable platen 32 that can move up and down, and a platen displacement adjustment mechanism corresponding to the movable platen and used to drive the movable platen to move up and down. The discharge printing head is used to output printing materials (such as molten plastic) to the forming printing table, and the printing head displacement adjustment...

Embodiment 2

[0040] Embodiment 2: In this implementation, the air cylinder / oil cylinder in Embodiment 1 is replaced by a servo air cylinder / servo oil cylinder. In addition, whether it is an air cylinder / oil cylinder or a servo cylinder / servo oil cylinder, as long as the height adjustment of the movable platen can be realized, any other commonly used adjustment mechanism, such as a screw mechanism, can also be used.

Embodiment 3

[0041] Embodiment 3: the basic structure and implementation mode of this embodiment are the same as embodiment 1, and its difference is:

[0042] like Figure 11 As shown in , the discharge channel is provided with a thermal insulation tube 23 coaxial with the discharge channel. The upper and lower ends of the thermal insulation tube are open. Thin material coloring channel 24 is formed between the wall and the channel wall of the discharge channel (that is, the inner wall of the discharge print head). The outlet of the coloring tube faces the outer wall of the heat-insulating tube, and a coloring check valve 521 is arranged at the outlet of the coloring tube. The passing direction of the coloring one-way valve is from the coloring pipe to the discharge channel, the highest point of the coloring port is lower than the highest point of the heat insulation cylinder, and the lowest point of the coloring port is higher than the lowest point of the heat insulation cylinder. The ve...

Abstract

The invention discloses a 3D printing device, comprising a main frame, a discharging printing head, a forming printing table, and a printing head displacement adjusting mechanism for driving the discharging printing head to move so as to change the position of the discharging printing head. The discharge print head is provided with a print head feed end for inputting printing raw materials, the discharge print head is provided with a discharge channel communicated with the feed end of the print head, and the forming printing table includes a fixed platen, at least A movable platen that can move up and down, and a platen displacement adjusting mechanism that corresponds to the movable platen one-to-one and is used to drive the movable platen to move up and down. The beneficial effects of the invention are that the structure is reasonable, can be adjusted according to the support requirements, and flexibly provides a part of the original support (non-printing support), thereby reducing the demand for the original printing support, improving the printing efficiency, reducing the risk of partial collapse of the product, Save support material and ensure product stability during printing.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a 3D printing device. Background technique [0002] 3D printer, also known as three-dimensional printer (3DP), is a machine that uses cumulative manufacturing technology, that is, rapid prototyping technology. 3D printing technology is a digital model file-based technology that uses bondable materials such as molten plastic to manufacture three-dimensional objects by printing layers of adhesive materials, that is, the technology of constructing objects by layer-by-layer printing. At this stage, 3D printers are mostly used to manufacture products. [0003] The 3D printer mainly includes a printing structure (print head), a forming printing table (on which the product is formed), and a printing head displacement adjustment mechanism (which can change the position of the printing head in space, so that the printed raw materials can fall on the forming printing table...
