The ActivArmor Story
Founded in 2014, ActivArmor is the brainchild of Diana Hall, an engineer, and entrepreneur from the heart of Colorado, who saw an opportunity after she experienced how low-tech the world of fracture immobilization was. As an industry that hadn’t changed in hundreds of years – literally relying on wrapping moisture-trapping and bacteria-cultivating fabric around the skin for weeks – it was ripe for disruption. While running a mentoring program for children in poverty, Diana came into contact with many kids who needed casts, whether it was due to domestic violence, other substandard living conditions, or just injuries from being a kid. One child, in particular, lived with elderly, disabled grandparents who couldn’t help him keep his fractured arm outside of the shower as he healed. With no other option to stay clean, he wore it anyway, causing skin breakdown and permanent scarring on his arm. Convinced that there was a better alternative to fiberglass, Diana 3D printed a cast out of the same plastic as Lego bricks and asked him to show it to his doctor – who was immediately taken by the idea and placed an order for several more.
