The article deals with the experimental investigation of the influence of material volume of a lattice structure on bending stress. FDM (Fused Deposition modelling) technique and ABS (Acrylonitrile Butadiene Styrene) material were selected for the samples production. Three types of samples with the same simple lattice structure and the same size of a basic cell 5 mm, but differ in a material volume ratio, were analysed experimentally. Minimally six pieces of the samples of each volume ratio were produced and tested using the ZWICK 1456 testing machine at an ambient temperature of 22 °C and at a relative humidity of 60 % according to the standard EN ISO 604. The stress-strain diagrams have been plotted and the values of maximum stresses have been tabled. The measured data were statistically processed, and average values of bending stresses were calculated. Based on the results the behaviour of the structure has been mathematically described, while the results showed that the dependency has an exponential trend.
