SINCE the discovery of the phenomenon of hygroscopic expansion of dental casting investments when subjected to an environment of water, there has been considerable work carried out to investigate its behavior. The ultimate goal is to develop a technic based on this property capable of compensating for the casting shrinkage of dental gold alloys. The result of these efforts has been the establis...

This paper aims to design lattice structures for rapid-investment casting (RIC), and the goal of methodology is minimize defects that are related topology. RIC can take full advantage unprecedented freedom provided by AM. Since has multiple objectives, we limit our study already have good printability, i.e., self-supported open-celled, improve their castability. To find relationship between top...
