The Queensland Library Foundation (QLF) funding of the Tunley Globe digitisation project at State Library of Queensland has opened up a window into the exciting possibilities of photogrammetry and 3D printing technologies for this unique piece.
Digitising the Tunley Braille Globe
R.F Tunley’s Braille Globe is an intricate Braille globe invented in Queensland in the 1950s. The globe was originally created for vision-impaired children by Queenslander Richard Frank Tunley, known as the ‘Fairy Godfather of Blind Children’, who dedicated his life to improving outcomes for vision-impaired children and adults, producing Braille globes and maps. You can learn more about Tunley and a selection of his works that are in the State Library collections here .
State Library has used 3D capture techniques to create an SLS Nylon printed replica of the globe that is able to be touched as the original was intended to be experienced. The model is accompanied by open access resources including digital 3D models and 3D printable files.
The project involved creating 3D models of the globe using scanning techniques and photogrammetry to capture the finite details of it.

Access the source files
User testing at Braille House indicated that the Braille markings in the reproduction print were difficult to discern as the Braille on the original had been worn down. It was decided to enhance the Braille marks in the 3D printed version. This work was undertaken by an industrial designer to create even and legible Braille.3D printing
3D printing files
Access high-resolution printing files. These files were originally printed via MJF in Nylon.
Files suitable for FDM printers are currently in development and will be made available soon.
State Library worked with a number of collaborators to help realise this project including Christie Tamas at Dittolabs whose expertise helped guide the project and who completed the scanning and photogrammetry of the Globe; Josh O'Connell at onepointsix who helped enhance the models and made them ready for printing.
