Processing method of 3D printing sharp tracks

Abstract

The invention discloses a processing method of 3D printing sharp tracks. Motion track lines of each layer of 3D printing are arrays of multiple straight lines, the motion track lines are analyzed, andjudgment for a motion track sharp point is performed; the motion track lines are broken at the sharp point, and two multi-straight lines of the front and back motion track lines are obtained; the twomulti-straight lines are extended at the sharp point for a section respectively; the extended front and back motion track lines generate a new curve continously; the curve is converted into a multi-straight line to serve as a middle transition motion track line; and the 3D printing sharp track is replanned as follows: the front motion track line, the middle transition motion track line and the back motion track line, and a printing head on the middle transition motion track line does not perform discharging. By optimization of the printing motion path, deceleration, vibration and other conditions of a movement device in an actual movement process are reduced, the phenomenon of material accumulation at corners is avoided, and printing quality of 3D printing components is effectively improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a processing method for 3D printing sharp tracks. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. [0003] The design process of 3D printing is: for the components to be printed, first use computer modeling software to model, and then "partition" the built 3D model into layer-by-layer sections, that is, slices, to obtain the printing program, so as to guide the printer to print layer by layer . [0004] Specifically, before printing on a large-scale FDM (Fused Deposition Rapid Prototyping) machine tool, it is necessary to slice the component to be printed to obtain a printing program. When printing, the moving device moves according to the running trajectory in the printing progra...

Problems solved by technology

[0008] The embodiment of the present application provides a processing method for 3D printing sharp trajectories, which solves the problem of running track programs with sharp points for large machine tools in the prior art, and the movement device will decelerate and vibrate at the sharp points of the running track. This further affects the fused deposition process of 3D printing, leading to material accumulation at corners, and ultimately affecting the product quality of 3D printing components. By optimizing the printing movement path, the deceleration and vibration of the moving device during the actual movement are reduced, avoiding Corner accumulation phenomenon effectively improves the printing quality of 3D printing components
