Embodiment Construction
[0022] In the method for FDM printing cavity type mold of the present invention, the cavity type mold of printing is as follows figure 1 As shown, it consists of a profile wall 2 and a mold top 4. The printing of this type of mold adopting the method of the present invention is as figure 2 and image 3 As shown, it specifically includes the following steps:
[0023] 1) Input the 3D drawing of the cavity mold to be printed into the slicing software to generate the G code program for FDM printing, and then import the G code program into the FDM printer;
[0024] 2) Printing of the cavity wall: use the FDM printer to start printing the outer contour wall 2 of the cavity-like mold layer by layer with the open end of the mold on the workbench 1 as the bottom, and alternate layers to the inner wall surrounded by the outer contour wall 2 of the mold. The cavity is filled with support particles 7 until it is printed layer by layer to the top of the mold outer contour wall 2 and fi...

Abstract
The present invention relates to a method for FDM printing cavity type mold in the technical field of 3D printing of casting mould. code program, and then import the G code program into the FDM printer; 2) Printing of the cavity wall: use the FDM printer to print the outer contour wall of the cavity type mold layer by layer with the open end of the mold as the bottom, and alternate layers outward The inner cavity surrounded by the contour wall is filled with support particles until it is printed layer by layer to the top of the outer contour wall of the mold and filled with support particles; 3) Printing of the top: the FDM printer completes the printing of the top structure of the mold according to the G code program on the top of the mold. In the method of FDM printing cavity-type mold of the present invention, the support bone inside the mold is replaced by support particles, and layers are alternately filled while printing to improve printing efficiency, save the printing process of the support skeleton, and save printing time. Improve printing efficiency.
Description
technical field [0001] The invention relates to the technical field of 3D printing of casting moulds, in particular to a method for FDM printing cavity-type moulds. Background technique [0002] FDM is Fused Deposition Modeling, which is a printing process that uses 3D printing equipment to extrude hot-melt materials in a semi-fluid state, and the materials are instantly solidified to form a thin layer with a contour shape. The products printed by FDM molding technology have the advantages of good surface quality after processing, high dimensional accuracy, long service life and short production cycle. Therefore, with the continuous improvement of 3D printing technology, FDM molding technology is more and more widely used in the foundry industry. [0003] The manufacturing process of FDM molding technology is a layer-by-layer smearing accumulation process, which is similar to printing figure 1 When the cavity mold is shown, the traditional printing method needs to print th...
