In this work we investigate how Braille characters can be produced through the upcoming 3D printing technology. Braille characters were experimentally printed through the widely diffused Fusion Deposition Modeling method, by different printing approaches: by using a professional-level printer, a low-cost 3D printer and a novel printing strategy optimized for Braille. Such novel printing strategy was developed to overcome common 3D printing issues, in particular on low-cost printers introduced by small details such as Braille dots. Braille writing samples produced using different techniques were compared in terms of geometrical defects. Finally, a human study enrolling visually impaired volunteers evaluated the different printing approaches in terms of readability and comfort in reading.

Abstract

In this work we investigate how Braille characters can be produced through the upcoming 3D printing technology. Braille characters were experimentally printed through the widely diffused Fusion Deposition Modeling method, by different printing approaches: by using a professional-level printer, a low-cost 3D printer and a novel printing strategy optimized for Braille. Such novel printing strategy was developed to overcome common 3D printing issues, in particular on low-cost printers introduced by small details such as Braille dots. Braille writing samples produced using different techniques were compared in terms of geometrical defects. Finally, a human study enrolling visually impaired volunteers evaluated the different printing approaches in terms of readability and comfort in reading.
