Development and commercialization of ultra-safe 3D printed motorbike helmets

摩托车手是最易受伤害的道路使用者之一。创伤性脑损伤（TBI）是摩托车手在道路交通碰撞中最常见的伤害，往往是致命的，并会产生改变生活的后果。TBI主要是由旋转运动引起的，目前的认证标准只测试直线运动。如果旋转运动可以减少30%，那么近一半的TBI死亡将被消除。因此，改进摩托车头盔是一个重要的机会。由于大脑模拟和建模，我们对导致TBI的生物力学的理解得到了显著的发展。此外，使用3D打印技术开发复杂的晶格结构也更经济实惠，因为有更广泛的合适的吸能材料。HEXR开发了世界上第一个使用3D打印的定制自行车头盔。帝国理工学院是世界领先的TBI和头盔测试专家。通过这个为期18个月的工业研究项目，HEXR有限公司和伦敦帝国理工学院正在合作开发一种摩托车头盔，这种头盔可以提供最低的TBI机会，可能挽救数千人的生命，并减少TBI给英国经济带来的150亿英镑的经济成本。

Motorcyclists are among the most vulnerable road users. Traumatic brain injury (TBI) is the most common injury that motorcyclists sustain in road traffic collisions, which can often be fatal and have life changing consequences. TBI is predominately caused by rotational motion and currently the certification standards only test for linear motion. If rotational motion could be reduced by 30%, nearly half of fatalities caused by TBI would be eliminated. Hence there is a significant opportunity to improve motorbike helmets. Our understanding of the biomechanics that cause TBI has grown significantly thanks to brain simulation and modelling. Also development of complex lattice structures using 3D printing is more affordable with a wider range of suitable energy absorbing materials.HEXR has developed the world's first custom fit bicycle helmet using 3D printing. Imperial College are the world leading experts in TBI and helmet testing.Through this 18-months industrial research project, HEXR Ltd and Imperial College London are collaborating to developing a motorbike helmet that provides the lowest chance of TBI, potentially saving thousands of lives and reducing the £15 bn economic cost of TBI to the UK economy.
