A 3d printing device

Abstract

The invention discloses a novel 3D printing device. The 3D printing device comprises a shell, wherein a through hole is formed in the left side of the lower surface of the shell, and the front surfaceand the back surface of the inner wall of the through hole are fixedly connected through multiple first connecting rods; the lower surface of the inner wall of the shell is fixedly connected to the bottom end of an electric push rod, the upper surface of the inner wall of the shell is fixedly connected to the top end of a telescopic device, the electric push rod and the telescopic device are located on the right side of the through hole, and the opposite ends of the electric push rod and the telescopic device are fixedly connected to the surfaces, away from each other, of the two supporting rods. According to the novel 3D printing device, the electric push rod, the telescopic device, a cleaning device, a baffle, a third bearing, a sliding sleeve, a threaded cylinder and a threaded columnare arranged so that raw materials can be wiped more comprehensively when being used, the raw materials can further be prevented from entering a printer, and therefore influence on the appearance effect of a product is avoided; and meanwhile, damage to a printing head can be avoided so that normal use of the printer by people can be prevented from being influenced.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to a 3D printing device. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials. Print layers of adhesive material to create three-dimensional objects. At this stage 3D printers are used to manufacture products. The principle of a 3D printer is to put data and raw materials into the 3D printer, and the machine will build the product layer by layer according to the program. [0003] At present, impurities will inevitably fall on the plastic raw materials during the process of taking them. At present, people simply wipe the outermost side of the raw materials, and the impurities on the inner side of the raw materials cannot be remov...

Problems solved by technology

[0005] Aiming at the deficiencies of the existing technology, the present invention provides a 3D printing device, which solves the problem that impurities will inevitably fall on the current plastic raw materials during the process of taking them. Impurities inside the raw materials cannot be removed, which will cause impurities to enter the printer, which will not only affect the appearance of the product, but also cause damage to the print head, thus affecting the normal use of the printer
