This work investigates the potential of additive manufacturing (AM) as a cost- and time effective alternative for producing molds suitable for autoclave curing of carbon fiber prepregs laid up manually. The study focuses on two application domains: biomedical devices and structural components. The methodology combines CAD-based mold design, digital light processing (DLP- LCD) 3D printing, manual lamination of prepregs, autoclave curing, and final evaluation of the mold’s performance. The results highlight the viability of AM for low-volume, customized production- especially in biomedical applications, where geometrical complexity and personalization are key. In this context, the printed molds demonstrated excellent thermal resistance and dimensional accuracy, proving fully compatible with the curing process.
