Additive technologies play a significant role in research institutions as well as in the manufacturing sphere. It is also commonly used in the field of transport for preparation of prototype models of final use parts. The own additive manufacturing devices are very easy to operate. However, sufficient experience is needed to achieve the desired result. The operator have to know the basic knowledge and relations.

Presented paper deals with operational parameters which influence the production process in additive manufacturing and quality of produced components by Fused Deposition Modeling (FDM) technology. There are many of parameters which influence the final quality of produced parts, but also own production process. Paper describe the whole experimental evaluation of input parameters for digital model pre-processing with regards to examining measured strength parameters of produces parts, including the quality parameters, as roughness and accuracy. Measured values are statistically evaluated.
