Problems solved by technology

The disadvantage of this method is that the print head runs many times on each slice level, and the idling trajectory is long, resulting in low printing efficiency, and the surface of the slice layer will be strained due to the print head running on the slice level many times

Embodiment Construction

[0025] Below to image 3 The three-dimensional mold shown is taken as an example, and the printing method of the product outline in the FDM printing of the present invention is described in detail. according to figure 1 The printing process shown in the figure prints the three-dimensional model shown in the figure. The outer contour 1 of the three-dimensional model is a cuboid, and the inner contour is a triangular hollow structure and a circular hollow structure respectively. The specific printing method includes the following process:

[0026] In the first step, the three-dimensional slicing software will image 3 The three-dimensional model of the product shown is sliced ​​into 20 layers, read the three-dimensional data information of each sliced ​​surface, and convert the three-dimensional data information into two-dimensional graphic data information;

[0027] In the second step, according to the thickness requirements of the surface layer of the printed product and the ...

Abstract

The invention relates to a printing method of a product profile in FDM (Fused Deposition Modeling) printing, and belongs to the technical field of 3D printing. The method comprises the following steps: pre-identifying an internal profile and an external profile on each slice layer of a product; recording two-dimensional information of the inner profile and the outer profile; then, printing the outer profile and the inner profile of each pattern at once; then printing filling parts between the profiles; completing printing of one slice layer; then moving a printing head to a next slice layer, and repeating the printing process. By adopting the printing method disclosed by the invention, the moving times of the printing head on each slice layer and the printing idle stroke can be reduced greatly, scratches to a printing surface during idle stroke of the printing head are avoided, the printing efficiency is increased, and the printing quality is enhanced.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a method for printing product outlines in FDM printing. Background technique [0002] Fused deposition modeling (FDM) is a kind of 3D printing technology, which plays a vital role in the field of 3D printing. FDM molding technology mainly relies on the movement of the printing head and the printing platform to realize the construction of the three-dimensional model. In the entire Fused Deposition Modeling (FDM) process, the wire plays a vital role. The FDM equipment extrudes the material in a semi-fluid state, and the material is instantly solidified into a thin layer with contours, and the layers are piled up to form the entire three-dimensional part. . Its advantages are precise and stable dimensions, long service life and short production cycle, and it has gradually begun to be applied in the foundry industry. At present, when using FDM technology to print multi-contour...
