Abstract

Abstract

The scanning path of 3D printing is an important factor affecting printing quality and efficiency. On the basis of studying the printing principle and finite element simulation of Fused Deposition Modeling (FDM), this paper aims to give a method of interlayer coherent layered composite scanning path. Firstly, the process characteristics of reciprocating linear scanning and offset scanning were analyzed, and a layered composite scanning path with interlayer coherence was proposed; Then, a finite element model of the FDM forming process was established using the life and death element technology and experimentally verified. Combining finite element simulation and experiments, the results show that the scanning path proposed in this paper not only integrates the advantages of reciprocating linear scanning and offset scanning, but also enhances the coherence and integrity of printing through the extrusion method of interlayer coherence and layered composite.
