Computation of mechanical properties of parts manufactured by fused deposition modeling using finite element method

Abstract

The paper focuses on a problem of evaluation of strength of products manufactured using Fused Deposition Modelling technology. The presented research was aimed at developing a method for computation of deformation and stresses in any product manufactured using FDM technology, with consideration of important, strength-affecting process parameters. Finite Element Method calculations were realized using digital CAD models of the products, obtained by simulation of FDM process in a virtual environment. These models represent the macrostructure of additively manufactured elements. Results of calculations for sample geometries were verified by experimental studies. The obtained results are mostly correct, changes in approach are needed to make the computations possible to be performed in shorter time and with better results.
