Fused Deposition Modelling technology allows to produce elements of very complex shapes without any additional tooling, which is why it has a broad range of industrial applications. Possibility of manufacturing parts with controlled degree of internal filling allows to shorten the manufacturing time and reduce volume of used material. The paper presents influence of layer filling type on part capability of carrying loads and economical coefficients of the manufacturing process. A problem of mechanical properties is important especially in case of elements used as functional prototypes. The paper presents methodology and results of experimental strength tests of samples with various types of internal filling. As a build material for test samples, ABS material was used. Composite samples were also used the ABS matrix produced by Fused Deposition Modelling was filled with chemically hardening polyurethane resin in a process developed by authors. The samples were subjected to destructive testing and their strength properties were compared.
