The 3D Petra project sought to develop effective solutions combining tele- rehabilitation, Computer Aided Design (CAD) Computer Aided Manufacturing (CAM), and 3D printing to increase access to orthotic devices (a sub-set of AT) for use in emergencies and remote settings. Regarding the technology in use, only the shells of the orthoses were printed. The rest of the devices were assembled using conventional materials and components. Fitting also followed a conventional process. The project was implemented in the West Nile part of Uganda, specifically Arua District, within the refugee settlements of Omugo and Imvepi, including the catchment of host communities.
