3D printing is becoming more accessible every day, although it is still lagging behind conventional methods in terms of material properties and production time. The influence of different printing parameters on the characteristics of FFF printed parts has been the subject of research in many studies. Since each material behaves differently during printing, it is important to identify how the selection of the same printing parameters reflects on some of the important characteristics of parts made of different materials and how some of them (in this case mass) fits with the software predictions.
ABS, PLA and PLA+Carbon materials were used for comparison in this paper. The output parameters taken into consideration are surface roughness, dimensional accuracy and mass difference. The obtained values of these parameters, measured on the printed parts, were compared and analysed. The parts are made of the mentioned materials with similar printing settings (only the material specific settings where changed: printing temperature, build plate temperature, etc.) For each material 3 specimens were printed on the same FFF printer to determine which dimension accuracy can be expected (to scale the future designs of parts accordingly). This was also done to ascertain what properties of surface roughness can be achieved with these materials and settings. Finally, based on this procedure it is possible to determine what amount of material is going to be needed when compared to software predictions.
