Abstract
Manufacture of parts by the method of 3D printing, in particular, applying FDM (Fusing Deposition Modeling) technology, is a promising trend in many branches of mechanical engineering, architecture, construction, medicine, etc. This range of problems challenges three main directions of studies: FDM 3D printing technology, materials science and mathematical modeling of processes for evaluation of functional qualities, in particular, strength of products. This work is devoted to the third direction: evaluation of stress-strain state of products manufactured by 3D printing using FDM technology. The paper considers three stages of solving this problem: 1 — mathematical formulation of the problem, which includes universal balance relations, determining equations of mechanical behaviour of the material; 2 — method of numerical solution of the problem; 3 — solving specific problems in order to determine patterns of thermomechanical processes and provide recommendations for technological settings of 3D printing. 10 Ref., 12 Figures.
Keywords: additive technologies, FDM 3D printing, mathematical modeling, stress-strain state
