Technical and Economic Aspects in the Development of Additive Technology

Sažetak

This paper studies the importance and development of additive technology through technical and economic aspects. The technical aspect includes research about the influence 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 different materials (PLA, PETG and PA12) and two subsequent treatments (compressed air and glass bead blasting). Surface roughness parameters (R_a, R_z and R_max) were measured and analyzed after different 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 profitability 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 influence 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.
