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.

The work done in this study is a preliminary investigation into the possibility of modelling the filling and solidification process of castings in molds made with the additive method. The work originated from an experiment to produce a bronze casting with a high tin content in an additive mold. The mold filling and solidification simulation was carried out in the MAGMASOFT program, and the lambda thermal conductivity coefficient used in the program’s material database was corrected based on the actual temperature values of the printed form. The results were compared with the modeling results for the physical properties of furan molds based on the program database. The microstructure of the castings obtained in the compared forms was assessed.
