Optimization of properties of 3D printed patterns for the technology of casting into ceramic shells
Štěpán, Radim ; Horáček, Milan (referee) ; Krutiš, Vladimír (advisor)
This thesis is focused on optimizing the 3D printed patterns used for investment casting into ceramic shells technology. The technology of hybrid investment casting and complete process of ceramic shells manufacturing is described in this thesis. During the burnout of the 3D printed pattern a problem with shell cracking arises. This problem was solved by optimizing the 3D printed pattern – the amount of pattern infill and venting the pattern cavity. The optimizations were successfully verified on the sword guard pattern.
