Imagine walking into a large room, eyes closed, using only a cane and your hands to navigate. The room includes a hallway, a set of stairs and a reception desk in the center of the floor. Everything is new and feels like an obstacle.
For Veterans with blindness or low vision, this experience is a daily reality. But with VA’s Blind and Visual Impairment Rehabilitation Continuum of Care, Veterans with visual impairments are achieving independence in daily life through skilled rehabilitation training in orientation and mobility, daily living activities and more.
3D printing technology improves tactile maps for Veterans
To help Veterans navigate unfamiliar or complex locations, clinicians build tactile maps of rooms, buildings and city blocks. Tactile maps like these are critical for helping Veterans develop new skills in mobility and orientation. Resourceful Blind Rehabilitation Specialists have long built them out of craft supplies, constructing scale models of city streets, VA hospitals and home addresses with immaculate care and detail.
When the Central Blind Rehabilitation Center at Edward Hines Jr. Hospital received a 3D printer, years of resourceful thinking paid off. Blind Rehabilitation Specialists wondered how 3D printing might improve the efficiency and accuracy of tactile maps; with this innovative mindset, the next iteration of tactile maps was born.

Today, multiple sites in the VA Blind and Visual Impairment Rehabilitation Continuum of Care can print tactile models of home addresses, street layouts and buildings in a handful of hours. Before, it took days. Importantly, the maps are now depressed, rather than raised, allowing Veterans to trace their own neighborhood or hospital campus with their fingers, feeling for difficult obstacles like busy intersections or complicated corridors.
Blind and Visual Impairment Continuum of Care Programs are exploring other use cases for 3D printing technologies, including adaptations to appliances, cane holders and Braille games, like playing dice. Evi Klein, Service Chief at the Western Blind Rehabilitation Center in Palo Alto, CA, and her team are partnering with museums to make art more accessible to the visually impaired through 3D models of visual sculptures. Through innovative technologies and dedicated staff, VA is increasing independence and safety for Veterans with visual impairments.
