This project explores an educational approach that equips industrial design students with hands-on, practical knowledge of molding by leveraging 3D printing technologies. Recognizing that many students struggle to grasp the complexities of moldability and its implications in mass production, this method bridges theoretical understanding and production realities. By integrating digital modeling with low-cost mold-making via 3D printing, students gain firsthand experience with form, parting lines, draft angles, and functional constraints. This pedagogy prepares students to design for manufacturability, maintain design intent through production, and reduce costly downstream errors—ultimately increasing their industry readiness and confidence in navigating manufacturing processes.
