Sažetak
This paper studies the importance and development of additive technology through technical and economic
aspects. The technical aspect includes research about the infl uence of surface inclination and layer thickness
on the surface roughness of the produced test samples. Two AM technologies or processes (FDM and SLS)
were used, with the use of three diff erent materials (PLA, PETG and PA12) and two subsequent treatments
(compressed air and glass bead blasting). Surface roughness parameters (Ra, Rz and Rmax) were measured and
analyzed after diff erent manufacturing conditions. Their variability and statistical analysis are presented.
From the obtained results, it is evident that with increasing slope (from 0° to 90°) the values increase to a
maximum (between 10° and 40°), after which they decrease (from 50° to 90°), while increasing the thickness
of the layer causes higher values of roughness parameters. Also, the aim of the paper is to determine the
economic profi tability of the used procedures, that is, the impact of the manufacturing procedures on the price
of the product. Modern and innovative materials and technologies are used in the research. By using innovative
technologies, we infl uence on sustainable development, which speaks of the fact that we need to meet our
needs with quality, while taking care that the generations that come after us also have this opportunity.
