👉 The term "epitrochoidal" refers to a type of material that has an extremely high degree of porosity, typically characterized by a low density and small size. This property allows it to be used in various applications such as aerospace, automotive engineering, and construction. In the context of materials science, epitrochoids are often used for their unique physical properties, which make them suitable for various applications due to their high porosity and low density. These characteristics can enable them to be
