Embodiment Construction

[0043] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

[0044] A method for quickly removing a 3D printing support of the present invention comprises the following steps:

[0045] (1) Use 3D software to build part models and save them in .STL format;

[0046] (2) Import the part model saved in the .STL format into the slicing software to add support and slice;

[0047] (3) Identify and separate the slice information of parts and supports in step (2), extract the slice information of the start and end of supports and save them to the control system;

[0048] (4) Before the printing of the support structure starts, the control system controls the media material nozzle to print a layer of media material on the substrate or the pre-formed part entit...

Abstract

The invention discloses a method for rapidly removing a 3D printing support. According to the main achieving manner of the method, a medium material printing head is used for printing a layer of easily degradable material before and after support printing, the support and a component are isolated through the medium material, the component and a substrate are isolated through the medium material, and the substrate and the support are isolated through the medium material. After component printing is over, a model is taken down, the medium layer is degraded, the medium material at the above part is dissolved, and the support structure naturally disengages from the surface of the component. The method is applicable to FDM, 3DP and other 3D printing technologies in which supports need to be added, support removal is fast and efficient, the component surface quality is not affected, the material cost is low, and a forming system is simple in structure.

Description

technical field [0001] The invention belongs to the field of additive manufacturing, in particular to a method for quickly removing 3D printing supports. Background technique [0002] Additive Manufacturing (AM), commonly known as 3D printing (3-Dimension Printing), is different from the traditional material removal processing technology represented by turning, milling, planing, grinding, etc. The technique of manufacturing solid parts by layer-by-layer accumulation of materials under control. [0003] Additive manufacturing technology originated in the 1980s. Its core idea is "dimension reduction manufacturing" that is first discrete and then stacked. Therefore, additive manufacturing technology is not sensitive to the complexity of the shape. The use of additive manufacturing can save intermediate links and directly Create parts with complex shapes. Accurate, efficient, fast in response, and capable of personalized manufacturing, 3D printing technology is being widely us...
