Abstract

3D tisk je dolgotrajen in drag proces, ki se v praksi uporabi, ko modela ni možno obdelati s konvencionalnimi načini obdelave. Ekonomičnost procesa 3D tiskanja lahko izboljšamo z ustvarjanjem bolj poroznega materiala. Pri visoko tlačnem litju aluminijevih zlitin prihaja do hitrega odvoda toplote preko materiala orodja v hladilni medij, ki se pretaka po hladilnih kanalih orodja. Poroznost materiala bistveno spremeni prenos toplote in mehanske lastnosti materiala v primerjavi z materiali brez poroznosti. V magistrskem delu je obravnavan prenos toplote v 3D tiskanih vložkih orodij za visoko tlačno litje aluminija. Hitrost odvoda toplote iz ulitka bistveno vpliva na mehanske lastnosti litega materiala, zato je pomembno obravnavati vpliv poroznosti natisnjenih vložkov v orodjih za tlačno litje.

Secondary title: Evaluation of porous 3D printed materials for the production of high pressure die casting tool inserts
Secondary abstract: 3D printing is a time-consuming and expensive process that is used in practice when the model cannot be processed with conventional processing methods. The economic aspect of 3D printing process can be improved by creating more porous materials. In the case of high-pressure casting of aluminum alloys, heat is rapidly dissipated through the tool material into the cooling medium, which flows through the cooling channels of the tool. The porosity of the material significantly changes the heat transfer and mechanical properties of the material in comparison to the materials without porosity. The master's thesis deals with heat transfer in 3D printed tool inserts for high-pressure aluminum die casting. The rate of heat dissipation from the casting significantly affects the mechanical properties of the cast material, so it is important to consider the influence of the porosity of the printed cartridges in die casting tools.
