Abstract

In order to study the influences of process path planning (extrusion path，printing speed and extrusion amount，etc.) of fused deposition moldeling (FDM) 3D printing technology on printing quality and printing efficiency，and improve the printing effect of FDM，three different process software (QidiPrint，FlashPrint and Simplify3D) were used to plan the process path. By analyzing the processes of three different process software path planning algorithm and print the entity model， it is found that although three extrusion ways are different，but they all adopt the way of compound extrusion，it will maximize the advantages of offset extrusion and reciprocating linear extrusion，and the outside-in extrusion mode’surface quality is better. The design of interlayer coherent trajectory can increase the consistency of printing and make the product more holistic. By reasonably arranging path can improve the quality of the mode’s surface，reduce the empty path in the process of printing，reduce the “step effect”and the phenomenon of drawing，save printing time and dosage of consumables.
