description: The theme of the graduate qualification work: "Finite element modeling of the 3D printing process". This work is devoted to the study of the process of 3D printing modeling and obtaining a stress field, deformation from the expected shape of the part due to cooling. Tasks that were solved in the course of the study:Confirm that a change in temperature causes thermal deformations in the material, and the limitation of thermal expansion leads to the appearance of stresses. Simulation of additive manufacturing steps on test geometry using Ansys finite element modeling package. Carrying out a study with modeling of the layer-by-layer printing process for a part made of ABS plastic. Obtaining temperature distribution fields, residual stresses and deformations at different orientations of the part in the print chamber with subsequent verification. Temperature distribution fields were obtained for each print layer on a test model after topological optimization and on a model made of ABS plastic. Also, residual stresses and deformations in the part after cooling were calculated. The following has been confirmed: a change in temperature causes thermal deformations in the material, and the limitation of thermal expansion leads to the appearance of stresses. The results of calculations are obtained for different orientations of the model describing layer-by-layer printing in the Ansys package in the print chamber.
