Study of FDM technology applications in the casting production of GTE details

Abstract

FDM is an additive manufacturing technology that can be effectively used to make investment casting models. This method is considered economical in a single production, since it does not require the manufacturing of expensive equipment. However, the roughness of models surface made by FDM printing is significantly lower than wax models obtained by traditional way - using metal and elastic silicone molds, that ultimately affects the roughness of castings. In this work, was studied the use of FDM printing technology for materials: REC CAST, PVA and Wax3D from company the “Filamentarno!”, used in molds to obtain models, as well as a combined method for wax models production. FDM printing technology is especially suitable for producing models with internal channels and cavities through the use of water-soluble support materials.

Stress relaxation in samples made of acrylonitrile butadiene styrene material manufactured by fused deposition modelling

“…Due to its popularity, FDM technology has found a wide range of applications use in various sectors of production [1]. In the paper [3] applied fused deposition modelling technologies in the foundry industry to manufacturing mold and casting models. The article [4] shows the use of FDM technology in improving the areodymium of a wing section by printing ribs using this technology.…”
