Embodiment 1

[0020] 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.

[0021] The specific implementation process of the method for detecting the flatness of the 3D printing powder surface is as follows:

[0022] 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;

[0023] 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

[0031] 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.

[0032] The specific implementation process of the method for detecting the flatness of the 3D printing powder surface is as follows:

[0033] 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;

[0034] S202, rese...

Abstract

The invention discloses a method for detecting the flatness of a 3D printed powder laying surface, and belongs to the technical field of 3D printing. The method is used for solving the problems that initial precision of the flatness of the powder laying surface of 3D printing equipment is low in adjusting efficiency and inaccurate. The method comprises the steps of selecting a to-be-printed product, setting a printing path, setting a data acquisition point path, collecting data, processing the data, judging the flatness of the powder laying surface and the like. Through the method, the production preparation time is greatly shortened; the adjusting precision of the powder laying flatness can be controlled within the range of 0.05 mm, and the precision is improved by dozens of times compared with manual adjustment, so that precise printing of the product and high precision of the equipment are achieved; and the production efficiency is improved, and the production cost is reduced.

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...
