Study on the influence of variable angle parameters in 3D printing process of multi-DOF robot
In order to solve the bottleneck of insufficient preparation capability of traditional three-axis printing in the curved field and overcome the defects such as step effect,this article designs and develops a direct-writing 3D printing platform based on multi-degree-of-freedom robotic arm,and conducts printing experiments using silicone rubber material.This article systematically investigates the influence of printhead printing angle on line geometry and multilayer line forming effect,and finally prepares structural samples with high conformability.This study shows that during the printing process with changing printhead guide angle,as the printhead guide angle increases,the line wideth of silicone foam shows higher consistency.In addition,when the guide angle is greater than 0°,the line cross-sectional shape is regular and the multilayer structure is well formed,which can also improve the line collapse problem at large span.The above experimental results reveal the multi-angle process rule for printing high conformal silicon foam.Compared with the traditional vertical direction or normal direction,the conformality of the printed silicon foam structure is higher when the nozzle guidance angle is greater than 0°,which can provide guidance for applications requiring high conformality,such as curved sensors and conformal antennas.
