Experimental Study on Shrinkage Rate of Outer Profile of FDM Melt Deposition Printing
Based on the issue of further improving the accuracy of FDM melt deposition molding,experimental re-search was conducted using PLA wire with a diameter of 1.75mm and 50mm×50mm×2mm thin plate model was ana-lyzed and established to analyze the movement path and wire shrinkage model of the 3D printed outer contour of molten deposition,The average shrinkage rate of the material during melt deposition molding was calculated to be 0.5047%under the process conditions of 0.2mm layer thickness,210℃printing temperature,and 25%filler material.Finally,the fea-sibility of average shrinkage rate was verified through validation experiments,providing a data reference for further im-proving the accuracy of complex parts'melt deposition molding.
