Method for 3D printing internal reinforcement structures in large spliced ​​display samples

Abstract

The invention discloses a method for 3D printing an internal reinforcement structure in a large-scale splicing display sample, and relates to the technical field of 3D printing. The method of 3D printing large-scale splicing display samples for the internal reinforcement structure is as follows: S1: Decompose the acquired 3D model 3D data suitable for the size of the printer, and use the software to automatically make card slots as splicing positioning; S2: The force analysis software is used to analyze the force structure of the 3D model, and the optimal shell wall thickness of the part is automatically calculated according to the force situation of each part. The present invention analyzes the force structure of the 3D model through force analysis software, and calculates the printed wall thickness of the part through the force part. At the same time, for the part with strong force, before shell extraction, use Boolean operation to pass the part of the steel pipe. The method of calculating and automatically generating holes on the 3D model can effectively transfer the force to the steel pipe, thereby effectively reducing the printing thickness of this part.

Problems solved by technology

[0004] The current mainstream 3D printer size is 600*600mm and 800*800mm. For products over 2 meters, they need to be disassembled and then spliced ​​into a whole. For such large display parts or samples, the printing time and printing weight It is to determine the price and production cycle of such parts or samples. The existing technology adopts the method of thickening the overall wall thickness, first shelling the solid model, and then splitting it. It is impossible to locally thicken the wall thickness, and the local strengthening operation is complicated. , the structure and cost of printing cannot be effectively controlled, so a method for 3D printing the internal reinforcement structure in large-scale mosaic display samples is proposed
