Method and device for 3D printing, storage medium and program product

Abstract

The invention discloses a method and device for 3D printing, a storage medium and a program product. The method for 3D printing comprises the steps that a three-dimensional model file is obtained, and at least one precision part is recognized; a boundary box is determined in a virtual space where the three-dimensional model is located; the three-dimensional model issegmented into multiple layers of slices; for each slice area of the height where the precision part is located, according to the position relation between the slice area and the boundary box, layer height merging operation is selectively carried out on the slice area; and a control code for execution by a processor of the 3D printer is generated based on a result of the layer height merging operation. According to the method disclosed by the embodiment of the invention, the layer height of the slice area of the part needing fine printing in the three-dimensional model is kept unchanged so as to ensure the printing precision, and meanwhile, the layer height of the slice area of the part not needing fine printing is merged, so that the slice area with a small layer number and a large layer height is formed, and the printing time of the part is shortened.

Description

technical field [0001] The present disclosure relates to the technical field of 3D printing, and in particular to a method and device for 3D printing, a computer-readable storage medium and a computer program product. Background technique [0002] 3D printer, also known as three-dimensional printer and three-dimensional printer, is a kind of process equipment for rapid prototyping, which is usually realized by printing materials with digital technology. 3D printers are often used to manufacture models or parts in mold manufacturing, industrial design and other fields. In recent years, 3D printing technology has been widely used in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms and other fields. high application prospects. [0003] The 3D printing method known in the art, Fused Deposition Modeling (FDM) is a me...

Problems solved by technology

Specifically, when a lower printing layer height is selected, the accuracy of the final printed three-dimensional object is higher, but because more layers need to be printed, the time required for printing is longer; on the contrary, when a higher When the printing layer is high, the time required for printing is shorter, but the accuracy of the final printed three-dimensional object is lower
