Finite element modeling of thermomechanical behavior of polymeric materials products at their manufacture by the method of layer-by-layer building-up

The 3D printing of functional components has significant advantages over conventional technologies due to the ability to fabricate parts with complex shapes without the need to produce specialized equipment. However, there are a number of geometric forms of objects, which require extra research, using 3D printing. Thin-walled parts are one of these objects. In the paper the mathematical model of thermal conductivity of the process of 3D printing of thin-walled products is constructed in order to determine the optimal parameters of technological process, which provide the minimum thermal deformation of the product and the maximum adhesion of layers
