The Applied Research and Innovation Team at Confederation College in Canada, in collaboration with the Canadian National Institute for the Blind (CNIB) and Vision Loss Rehabilitation Canada (VLRC), has developed a 3D-printed signage solution specifically designed for individuals with visual impairments. The project focuses on enhancing orientation within a training kitchen in Thunder Bay, where participants learn to prepare food safely.
Previously, the facility used paper-based Braille signs, which proved to be neither durable nor practical. Under the direction of Greg Gagnon, the research team identified an opportunity to create a more sustainable solution through additive manufacturing. A key challenge was achieving tactile readability using robust materials, as standard 3D printing techniques often produce sharp-edged surfaces unsuitable for Braille.
“The development of this signage required us to rethink conventional techniques,” said Greg Gagnon, Research Supervisor at Confederation College. “Using two different processes, we were able to ensure that the signs are both cost-effective and optimized for accessibility.”
To address the material and tactile challenges, the team developed a two-stage printing process. This method allows for both raised large-print letters and smooth Braille dots to be printed in a single production step onto durable plastic plates. The goal was to create an affordable, easy-to-install, and long-lasting alternative to conventional signage.
“Accessibility means removing obstacles, and initiatives like this have a significant impact,” said Tanis Boardman, Manager, Ontario Programs and Community Engagement, CNIB. “We are excited to collaborate with the College on this project, which will assist individuals with vision loss in Thunder Bay and raise community awareness about accessible signage.”
The initiative highlights how additive manufacturing can be applied in the social sector—not only for product innovation, but also to support inclusion and participation. Confederation College sees hands-on research as a key contributor to regional development and knowledge exchange between educational institutions, industry, and civil society.
