Abstract
One of the advantage of additive manufacturing technologies is the possibility to produce hollow section products, which are lighter, cheaper, faster to create and still they can have the required mechanical properties. Most of the times a 3D printed part's most important feature is the freedom of shape, and by setting the appropriate infill we can ensure the proper resilience as well. In this paper the different infill patterns and volume related percentages are compared by using the commercial Fused Deposition Modelling (FDM) technology. For the investigation non-standardized bending test were made with two loading orientation. From the results, the relation between the mass of the product and manufacturing time can be stated clearly, the pattern and percentage, as well as the decrease of the resilience in case the use of hollow areas in products.
