Extraterrestrial Regolith Simulant Database: Mechanical and Rheological Properties of Regolith Simulants

The project is to share an database on mechanical and rheological Properties of Regolith Simulants, particularly for 3D printing. More than 1000 data are collected from different resources for different types of regolith simulants, including their mechanical properties such as compression, tensile, bending strength, hardness, different printing conditions, and different types of printing methodologies. Their rheological properties of regolith simulants are also included, such as their mix ratios, their activator solutions, their setting times, and their viscosities. This database will provide an overview for future researchers on how they could select regolith simulants for their research and how their data compared to the existing data.
