| In recent years,the rapid development of 3D printing technology has become one of the important members of the manufacturing industry.FDM based 3D printer has become one of the most widely used printer types in 3D printing.However,although 3D printing technology is becoming more and more mature,there are still some small defects.For example,traditional 3D printing path planning is prone to generate gaps in the printing process,resulting in defects in the model,or unnecessary redundant accumulation,which will lead to the decline of print quality,efficiency,and material waste.In this paper,an algorithm for optimizing the path planning speed is proposed.The path width is optimized by adjusting the moving speed of the nozzle of the 3D printer,so as to improve the above problems.The method proposed in this paper is different from the traditional way of adjusting the path planning algorithm.The traditional way of adjusting focuses on the adjustment and optimization of the mathematical algorithm,while the method proposed in this paper focuses on the control parameters of the printer,and optimizes the path planning algorithm through different directions.Specifically,this paper adjusts the traditional path planning and optimizes the filling path by adjusting the traveling speed of the nozzle.Given a specific path filling algorithm,calculate the original path spacing and angle information,explore the impact of different path control parameters on path filling,through speed optimization,get the best path control parameters.Finally,by modifying the machine control programming language Gcode locally,the optimal control is realized.This method can effectively improve the filling efficiency and quality of 3D printing path,and achieve high-quality 3D printing. |
