Although Additive Manufacturing (AM) provides high degree of design freedom, there are barriers to the progression of AM in industries. Accordingly, a design method is proposed to guide designers to leverage both AM and conventional manufacturing (CM), which will lead to mass customization. The design method emphasizes on redesign of the protective structure of UAV that inspects inside buildings or ships. The protective structure is divided into two categories: joints and rods by demonstrating the design method. The Joints are redesigned with lattice structure and then fabricated by AM, while the rods are fabricated by CM, which is made of carbon fiber. This study provides fundamental information that will support single part fabrication with multiple manufacturing processes that lead to multi-material application into part design.

Additive Manufacturing (AM) provides high degree of design freedom. This enables designers to fabricate complex geometries and enhance performance that cannot be achievable by conventional manufacturing. However, the high degree of design freedom from AM makes designers challenging to fully add design benefits from AM, because designers are not familiar with AM, which is new technology. In this study, we propose a bicycle helmet design process by considering AM capabilities. The objective of the helmet design is to redesign conventional bicycle helmet and then add new design benefits like lightweight and storage function, while keeping safety requirements of the conventional helmet. First, we analyze customer needs. Then, the customer needs are translated to engineering requirements. Lattice structure is utilized to achieve lightweight and safe helmet. Foldable structure of the helmet is proposed to make volume of helmet reduced and make the helmet as a storage of bicycle related items.
