Deposition strategies and resulting part stiffnesses in fused deposition modeling

In the Fused Deposition Modeling (FDM) process, the choice of deposition st rategy plays an important role. In this paper the effects of different depo sition paths on this deposition based LM process are investigated. Some var iations on the current deposition strategies are also proposed The stiffnes s of parts manufactured by the different strategies is experimentally deter mined It is then compared with an analytical model developed using laminate analysis. A good conformance of the laminate model to the experimental res ults suggests that the laminate model can be used as a design aide to help the designer tailor the deposition strategy to the stiffness requirements.
