3D printing device

Abstract

The invention discloses a 3D printing device which comprises a main rack, a discharge printing head, a molding printing table, and further comprises a printing head displacement regulating mechanism for driving the discharge printing head to move to change the position of the discharge printing head, wherein a printing head charge end for inputting printing raw materials is arranged on the discharge printing head; a discharge channel which is communicated with the printing head charge end is arranged in the discharge printing head; the molding printing table comprises a fixed table board, at least one movable table board capable of moving up and down, and a table board displacement regulating mechanism which is in one-to-one correspondence with the movable table board and is used for driving the movable table board to move up and down. The 3D printing device has the beneficial effects that: the structure is reasonable, regulation can be carried out according to supporting needs, one part of original support (instead of printing support) can be flexibly provided, so that original printing support requirements are reduced, printing efficiency can be improved, local collapse risks of products are reduced, support materials are saved, and product stability in a printing process can be guaranteed.

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...

AI Technical Summary

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.
