Design And Implementation Of Intelligent 3D Printing Path Planning System

3D printing technology has been widely used in manufacturing processes that are different from traditional material manufacturing,and it is easy to produce individualized parts by means of additive manufacturing.Through simple modeling,stratification,path planning,print stacking,and rapid manufacturing,individual parts can be formed in a very short time.Path planning,as a key part of 3D printing,controls the overall printing by planning the motion track of the print head,which has a huge impact on print quality and printing efficiency.At present,the commonly used Z-shaped and paranoid contour path planning algorithms have obvious advantages and disadvantages,and the performance of large-scale parts is poor.With the popularization of artificial intelligence,the intelligent 3D printing path planning algorithm will attract attention.At present,3D printing software at home and abroad has taken shape,but there is no 3D printing system for path planning research.Therefore,based on the research of traditional path planning algorithm,this paper studies the intelligent path planning based on the idea of partition and TSP traveler.algorithm.After the slice is obtained,the two-dimensional contour of each layer is firstly concavely convexly decomposed using the Bayazit algorithm,and the path of each sub-area is adaptively printed along the long-axis zigzag according to the specific contour,and the number of print paths is reduced as much as possible.And start and stop shifting,and finally the connection path of each sub-partition is simulated as the connection of TSP traveling salesman problem,and the mature intelligent algorithm genetic algorithm is used for 400 iterations to complete the path planning of the whole contour.This paper develops an intelligent 3D printing path planning system.After the sliced layered 2D contour point set is imported,the print path width is set,the path is generated using the intelligent path planning algorithm,and the experimental parameters are output,and finally the path is obtained.Convert to G-code code for 3D printer printing.
