Streszczenie / Summary:

Fused Deposition Modeling (FDM) is a widespread additive manufacturing technology, which allows to obtain models of complex geometry without any tooling, directly from the digital CAD representation. It has been found out during numerous studies, that strength of products obtained using this technology is lower than strength of products manufactured of the same material, but with conventional technologies such as injection molding. Furthermore, the strength is greatly affected by orientation of part in the working chamber during manufacturing. The paper describes experimental research aimed at examining the influence of the orientation on impact strength of ABS parts produced with this technology. Test samples of various orientations were prepared and subjected to Charpy impact test. Also, a number of reference samples were prepared with injection molding of the same ABS material. Analysis of research results confirmed the assumptions made and allowed to make some important observations regarding strength of models produced with FDM technology.
