【 摘 要 】
One of the most challenging task regarding the design and the engineering of a new 3D printing part is to navigate through the vast number of technologies and materials that are offering variations in properties (like biodegradability, dimensional accuracy, surface finish and post processing requirements) available in order to determinate the solution that is best suited for the desired application. In this paper have been analysed, on an example, the 3D printing mechanism of a part, pipe type made from PET-G. The phenomena of contraction and the thermal stresses that appear during the process were revealed. The considerations formulated on this example lead to the conclusion that the pieces produced by 3D printing after FDM are heterogeneous both in terms of physical and mechanical properties and the stress state due to the deposition of the layers.
