The current article is aimed at design and development of a light head gear for sports that can be additively manufactured. In this article, a 3D-printed modular design of sports helmet is designed and studied with respect to a specific sport namely cycling. For better safety of riders, it is expected to be light in weight, contain minute openings and possesses the same safety standard as served by the current market available produc. The helmet design is based on modular structure with detachable components that can be interchanged depending on the use. In this study, an auxetic structure is studied for lightweight and high strength as compared to conventional helmets. The porous structures will also allow better precipitation and increased comfortability to the user. Apart from this, emphasis is also given on the comfort level, lower cost and especially being lightweight. In this proposed design, the mechanical strength and focus on building characteristics to resist forces in both shear and compression, by generating dome-like, synclastic surfaces when bent or by moving more mass under the point of compression is done along with evaluation of results of impact testing on the designed helmet from different sides, will be carried out leading to determination of several factors like linear acceleration, rotational acceleration, etc. of the head form through simulation and validated experiments.
