Three-dimensional printing platform adjusting method and three-dimensional printer

Abstract

The invention provides a three-dimensional printing platform adjusting method and a three-dimensional printer. The three-dimensional printing platform adjusting method comprises the processes of conducting calibration on flatness of each supporting component, wherein the process of conducting calibration on flatness of one supporting component comprises the steps that a backward-direction print head of a three-dimensional printing platform is moved to the calibration position; the print head is moved above the supporting component in need of calibration; the three-dimensional printing platform is moved toward the print head and to the preset zero position at the first resolution ratio; a control unit calculates the current pressure value; whether the current pressure value equals to the preset pressure value or not is judged; if not, the current pressure value is made to be equal to the preset pressure value by adjusting the position of a pressure sensor. The invention further discloses the three-dimensional printer using the three-dimensional printing platform adjusting method. According to the three-dimensional printing platform adjusting method and the three-dimensional printer, by conducting calibration on the supporting components and utilizing the pressure sensors as calibration benchmarks, an article carrying plate can be effectively adjusted to be flat, and formation quality can be further improved.

Description

technical field [0001] The invention relates to the field of printing, in particular to a three-dimensional printer and a method for adjusting a three-dimensional printing platform of the three-dimensional printer. Background technique [0002] A 3D printer, also known as a three-dimensional printer, is a machine that uses rapid prototyping technology. Based on digital model files, it uses molding materials to construct three-dimensional entities by layer-by-layer printing. Before printing, it is necessary to use computer modeling software to model, and then "partition" the built 3D model into layer-by-layer sections, that is, slices, so as to guide the 3D printer to print layer by layer. 3D printers have been widely used in the product manufacturing industry. The working principle of 3D printers is basically the same as that of traditional printers. It consists of control components, mechanical components, print heads, consumables (that is, molding materials) and media, and...

Problems solved by technology

[0003] The 3D printing head extrudes filaments onto the 3D printing platform to form a three-dimensional entity. When the printing platform is not parallel to the nozzle of the printing head, that is, when the printing platform is tilted, the printed model is prone to warping or extruding filaments. There is a problem that the material cannot be connected, and the scrap rate of the model will be high

Therefore, after the printer ...
