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

Abstract

The invention provides a three-dimensional printer and a three-dimensional printing platform adjustment method. The three-dimensional printer comprises a printing head device moving in a horizontal plane, a three-dimensional printing platform moving in a vertical direction, a control unit and a display unit, wherein the printing head device comprises a permanent seat, a printing head and a pressure sensor module; the pressure sensor module is detachably arranged on the permanent seat; the printing head is detachably arranged on the pressure sensor module; the three-dimensional printing platform comprises more than three adjusting components, a loading plate and a supporting table; the loading plate is arranged on the multiple adjusting components; and the multiple adjusting components respectively penetrate through the supporting table, are detachably connected to the loading plate and are used for enabling the loading plate to move in the vertical direction. According to the three-dimensional printing platform adjustment method, the loading plate is used for corresponding to the position of the first adjusting component so as to measure a first pressure value which serves as the calibration reference of other adjusting components. According to the three-dimensional printer, the weight of the printing platform can be reduced, the cost is reduced, and the adjustment accuracy ofthe three-dimensional printing platform can be improved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional printers, 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 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 (ie molding materials) and media. The printing principles a...

Problems solved by technology

[0003] The 3D printing head extrudes filaments onto the 3D printing platform to form a 3D 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

However, this method of setting the pressure sensor on the 3D printing platform will not only increase the weight of the printing platform, but may cause the deformation of the printing platform to affect the printing quality, and because the printing platform is equipped with a heating plate, the pressure sensor is set close to the heating plate. It is easy to cause abnormal pressure signal line, causing problems such as unstable pressure sensor signal

At the same time, the adjustment method of the 3D printing platform uses the preset pressure value as a reference to adjust all the support points, which is not conducive to practical application. Deviations may easily cause inaccurate adjustment accuracy
