In essence, EPS prototypes offer a practical and efficient way to test and refine designs before committing to full-scale production, saving time, resources, and potential errors. An EPS prototype is a physical model created using expanded polystyrene foam, a rigid, lightweight material composed of microscopic closed cells formed by expanding polystyrene beads with steam. This foam is easy to shape, cut, and machine, making it ideal for creating prototypes quickly and affordably. EPS prototypes represent the look, feel, and function of a product concept, allowing designers and engineers to validate design ideas before final manufacturing.
