Modeling fused deposition of PLA by analysis of the layers

The realization of the additive manufactured components requires the understanding of the variables having an effect on the physical final geometry. One of them is represented by the initial digital information with required tolerance, in particular where the different parts such as planar and curved ones need to be connected together. The other important variable is represented by the extruding conditions in FDM of PLA blend materials. The temperature setting with which to reduce the induced tensions, the volume variation and warpage are determined.
