Embodiment 1

[0021] The data collection point in this embodiment is a triangle, and the triangle is an isosceles triangle. The data collection points are arranged along the two waists of the isosceles triangle, and there are 300 data points.

[0022] The specific implementation process of the method for detecting the flatness of the 3D printing powder surface is as follows:

[0023] S101, set the product to be printed as a flat panel, and set a triangle on the flat panel as a data collection point, and the two waists of the triangle are the data collection path; the area of ​​the triangle occupies the entire flat panel product At least half of the area, so that the collected data can accurately reflect the distance from the printing head to the powder coating surface;

[0024] S102, reset the print head to the printing starting position, make the print head reciprocate horizontally according to the flat product, and the print head can cover the entire flat product in one move, that is, one...

Embodiment 2

[0032] The data collection points in this embodiment are nine circles, that is, there are nine groups of data collection points in this collection. The data collection points are arranged along the sides of the circle, and each circle is provided with 300 data collection points. point.

[0033] The specific implementation process of the method for detecting the flatness of the 3D printing powder surface is as follows:

[0034] S201, setting the product to be printed as a flat panel, and setting nine circular data collection points on the flat panel, the clockwise direction of the circular circumference is the data collection path; the nine circular data collection points The points are evenly distributed on the flat plate, and the total area of ​​the nine circular data collection points is not less than half of the area of ​​the flat product, so that the collected data can accurately reflect the distance from the print head to the powder-spreading surface;

[0035] S202, rese...

Abstract

A method for detecting the flatness of a 3D printing powder surface, which belongs to the field of 3D printing technology, and is used to solve the problem of low efficiency and inaccuracy in the initial precision adjustment of the flatness of the powder surface of a 3D printing device. The method includes selecting a product to be printed , setting the printing path, setting the path of data collection points, collecting data, data processing and determining the flatness of the powder surface, etc., the time for production preparation is greatly shortened by this method; and the adjustment accuracy of the powder flatness can be controlled within In the range of 0.05mm, the accuracy is improved by dozens of times compared with manual adjustment, which realizes the precise printing of products and high precision of equipment, improves production efficiency and reduces production costs.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a detection method for 3D printing equipment. Background technique [0002] 3D printing technology is a kind of additive manufacturing technology, including melt extrusion technology and 3DP technology. In the application of 3DP technology, in order to obtain good printing products, it is necessary to control the thickness of each printing layer and the surface quality of each layer. , the smaller the layer thickness, the better the compactness of the product, the better the performance, the better the surface quality of the layer, the better the interlayer bonding of the product. The thickness of the layer can be set and is also determined by the accuracy of the equipment itself; while the surface quality of the layer is related to the raw materials used, the operating speed of the equipment, and the accuracy of the powder spreader. In the case of non-adjustable equipment a...
