Problems solved by technology

However, most of the current adaptive layering algorithms mainly study the relationship between layer height and step error, and there are still few solutions to the problem of model feature offset and loss.

Abstract

The invention discloses an adaptive layering method for preventing feature deviation of 3D printing model, including the creation of three-dimensional models, A mesh process is carried out on that three-dimensional model, to generate the STL file, reading the STL file, and preprocessing the data read from the STL file, to obtain the preprocessed data, recognizing the feature height on the three-dimensional model after gridding, A set of height data is obtained to adjust the spacing between adjacent feature heights, the height data is adjusted, The feature height is sliced at a position of thefeature height, and an adaptive slicing is performed between adjacent feature heights to obtain slice outline information, generate a print file, and print a 3D model. The invention ensures that the layered plane passes through the position where the model features are located, thereby retaining the three-dimensional model features, effectively preventing the feature deviation and loss caused by the layer-by-layer accumulation of materials in the printing process of the 3D printing model, and reducing the step error.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to an adaptive layering method for preventing feature deviation of a 3D printing model. Background technique [0002] 3D printing (3D Printing) technology, also known as Rapid Prototyping (RP) or additive manufacturing (AM), is a technology that manufactures three-dimensional solid parts through CAD design and layer-by-layer accumulation of materials. The specific implementation steps are as follows: firstly, use CAD design or reverse engineering to obtain a 3D model, and convert it into a simple and versatile STL (Stereolithographic) format or other operable format files for processing; In the layer direction, planes of different heights are intersected with the model to obtain a series of contour information; then according to the contour information, the printing path and other process parameters are determined, and the printer is controlled to stack and bond the ...
