Analysis of the Characteristics of Split Extrusion by Fused Deposition 3D Printer

Wang Ming-xiao

[Abstract]Analyze the differences in structure and working principle between FDM 3D printer integrated extrusion and split extrusion and their pros and cons through actual processing， and propose solutions to the problem of material blocking in split extrusion. The quality analysis of the test pieces printed with different printing speeds for integrated extrusion and split extrusion is carried out to illustrate the advantages of the split extrusion FDM 3D printer in work efficiency.
