3D printer with automatic adjusting type printing platform

Abstract

The invention relates to the technical field of 3D printing, in particular to a 3D printer with an automatic adjusting type printing platform, the 3D printer comprises a bearing frame, a printing platform and a gradienter, and the gradienter is fixedly mounted at the bottom of the printing platform; the device further comprises a sensing device and an adjusting device, the sensing device is fixedly installed at the bottom of the printing platform and comprises a sleeve, a connecting rope, a trigger ball and a sensing head, the sleeve is fixedly installed at the bottom of the printing platform, the two ends of the connecting rope are fixedly connected with the printing platform and the trigger ball correspondingly, and the connecting rope and the trigger ball are located in the sleeve. The inductive head is fixedly mounted at the bottom of the sleeve; the adjusting device comprises linear driving assemblies, the linear driving assemblies are fixedly installed on the bearing frame and distributed at the four corners of the bearing frame, and the driving ends of the linear driving assemblies are in transmission connection with the printing platform. The printing platform adjusting device overcomes the defects that a printing platform of an existing printer needs to be manually adjusted, and an unexperienced operator is difficult to adjust the printing platform to be in a horizontal state.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printer with an automatic adjustment printing platform. Background technique [0002] 3D printing technology is a kind of rapid prototyping technology, which is a technology that obtains the required model by layer-by-layer printing based on digital model files, using adhesive materials such as plastic or certain metal powders. In existing printers, if the printing platform is tilted, it may cause model displacement, fracture, or even print failure. [0003] To this end, Chinese patent CN202023227921.1 discloses a printing platform adjustment device and a 3D printer, which adjust the height and levelness of the printing platform assembly by operating a manual displacement stage, and at the same time, the level can detect the levelness of the printing platform assembly in real time, And through the level ruler, it can directly and reliably judge whether the printing plat...

Problems solved by technology

[0004] However, it still needs to be manually adjusted, which is extremely dependent on the experience of the operator. It is difficult for an inexperienced operator to adjust the printing platform to a horizontal state, and once the printer moves or shifts under the influence of external force, it needs to be adjusted again. Adjustment, the efficiency is low, and it is impossible to maintain a stable level. Therefore, there is an urgent need for a 3D printer that can automatically adjust the printing platform
