Embodiment 1

[0044] An embodiment of the present invention provides a 3D printing layering method, which is suitable for layering a three-dimensional model of a target object in 3D printing. In the 3D model of the target object, the gradient of the edge pixels reflects the degree of color change on the surface of the object, and the gradient of the edge pixels in the stacking direction is used to determine the layer thickness.

[0045] See figure 1 , the method specifically includes the following steps:

[0046] S1: Obtain the gradient of the edge pixels of the slice layer to be printed in the stacking direction, and record it as the pixel gradient of the slice layer to be printed;

[0047] Such as figure 2 As shown, the coordinate axes of the coordinate system where the 3D model 1 of the target object to be printed are located are x, y, z, and the direction of the z axis is the stacking direction of the slice layers when 3D printing the 3D model of the target object.

Embodiment 2

[0096] The embodiment of the present invention also provides a 3D printing method, the specific printing steps are as follows:

[0097] S10: Obtain the layer thickness of the slice layer to be printed through the 3D slice processing method described in Embodiment 1;

[0098]S11: Determine the amount of consumables required for printing the slice layer to be printed according to the layer thickness of the slice layer to be printed;

[0099] S12: Print the slice layer to be printed according to the layer thickness of the slice layer to be printed and the amount of consumables required for printing the slice layer to be printed.

[0100] The amount of consumables required for slice layers with different layer thicknesses is different, so it is necessary to calculate the required amount of consumables according to the layer thickness. Preferably, step S11 further includes:

[0101] S111: Obtain the amount of consumables required by the currently printed slice layer;

[0102] S11...

[0109] The gradient acquisition module 201 is used to acquire the gradient of the edge pixel points of the slice layer to be printed in the stacking direction, which is recorded as the pixel gradient of the slice layer to be printed;

[0110] A layer thickness acquisition module 202, configured to determine the layer thickness of the slice layer to be printed according to the pixel gradient of the slice layer to be printed;

[0111] The slice layer module 203 is configured to perform layering according to the layer thickness.

[0112] Further, the gradient acquisition module 201 also includes:

[0113] a coordinate acquisition unit, configured to acquire the coordinate values ​​of the edge pixel points;

[0114] a pixel value acquisition unit, configured to acquire the pixel value of the edge pixel point;

Abstract

The invention discloses a 3D printing layering processing method, device and equipment and a storage medium, and relates to the technical field of 3D printing. The method comprises the steps that the gradient of edge pixel points of a slice layer to be printed in the stacking direction is obtained and recorded as the pixel gradient of the slice layer to be printed; the layer thickness of the slice layer to be printed is determined according to the pixel gradient of the slice layer to be printed; and layering is conducted according to the layer thickness. According to the method, the layer thickness of the slice layer to be printed is determined according to the gradient of the edge pixel points of the slice layer to be printed, the relatively small layer thickness is adopted for the area with the relatively large gradient, better detail performance is achieved, the relatively large layer thickness is adopted for the area with the small gradient, and therefore the working efficiency is improved, and meanwhile the printing quality and the printing efficiency are guaranteed.

Description

technical field [0001] The present invention relates to the technical field of 3D printing, in particular to a 3D printing layered processing method, device, equipment and storage medium. Background technique [0002] At present, 3D printing technology mainly includes Stereo Lithography Apparatus (SLA for short), Selected Laser Sintering (SLS for short), Laminated Object Manufacturing (LOM for short), three-dimensional printing Ink printing technology (Three-Dimensional Printing, referred to as 3DP) and so on. The common feature of the above technologies is based on the digital 3D model file of the target object to be printed, using layering technology to cut the 3D model into several layers of slices according to a certain layer thickness, and transform the 3D object into several layers of 2D printed slices stacked. For example, in 3DP printing, three-dimensional objects are layered, and then bondable materials such as powdered metal or plastic are used, and each layer of...
