This paper presents an analysis of FFF/FDM (Fused Filament Fabrication / Fused Deposiotion Modeling) applications for production of casting patterns used in sand casting, with particular emphasis on short-run and prototype production. For this purpose, casting patterns of different shape and height of incremental layer (0.29 mm, 0.19 mm, 0.14 mm and 0.09 mm) were made of Z-ABS filament produced by Zortrax. Geometrical and dimensional analysis of the patterns was carried out, surface roughness parameters were measured, and a visual analysis of the surface was performed. In order to evaluate the conclusions observed based on the analysis of casting patterns, 130 x 102.5 x 37.5 mm sized shaped castings were designed and manufactured from aluminum and grey cast iron, which were also subjected to analysis. The last element of the research was a visual analysis of the reproduction of markings on the castings.
