Small Devices, Large Changes: Investigating the Impact of a University-Government 3D-Printed Assistive Technology Program on Residents with Disabilities.

Do-It-Yourself Assistive Technology (DIY-AT) has shown promise in expanding access to customized, low-cost devices, particularly for individuals whose needs are not met by professionally manufactured assistive technologies. In this paper, we present a study of the structure and impact of a DIY-AT program launched through a collaboration between a university makerspace and the Maryland department of disability Assistive Technology program. Using an Action Research approach, we examine how the program's institutional, technical, and informational infrastructure evolved over time and how recipients experienced and responded to the 3D-printed devices. Our findings demonstrate that university-government partnerships can enable the large-scale production and distribution of DIY-AT, while also fostering trust, advocacy, and interest in future participation among recipients and others in their communities. We also highlight ongoing barriers to design participation and identify new stakeholder roles that extend existing models of DIY-AT ecosystems.
