【 摘 要 】

Recent advancement in additive manufacturing (AM) enables us to make functional prototypes with the highest accuracy. Among various AM techniques, fused deposition modeling (FDM) is most popular due to its ability to make a complex shape in minimum time and least cost. However, the strength of the parts fabricated with FDM is always of primary concern so present approach provides a way to control localized mechanical property in FDM parts. Model of a 3D object is bifurcated into various subparts by incorporating stress data. All subparts are fabricated by using appropriate process parameters suited to their stress value. As the process parameters have a prominent effect on the strength of the part, hence the part fabricated contains better strength compared to conventional FDM approach.
