Modeling materials are substances used to create three-dimensional representations of objects or concepts. Common types include clay, plasticine, and foam, which can be shaped and molded by hand. These materials are often used in art, design, and education to help visualize ideas and prototypes. In addition to traditional materials, there are also 3D printing filaments like PLA and ABS that allow for precise and complex designs. These materials can be used in various fields, including engineering and architecture, to produce detailed models that aid in planning and development.
