A Proposed Method for Producing Embossed Dots Graphics with a 3D Printer

Abstract

This study examines embossed dots graphics produced with a 3D printer for the purpose of providing practical information to visually impaired people. Using 3D printing to produce tactile graphics has a benefit to make use of our cumulative assets in tactile graphics production: techniques and production tools. The author designed this study to specifically take up the following challenge: develop a system that would convert data created using embossed dots graphics drawing software for a braille embosser into data that could be used with 3D CAD software. The conversion would allow for completely customization of the size and shape of every dot, freeing us from the limitations in dot type associated with the braille embosser. Results are confirmed via physical measurements and tactile observation assessments.

The Effect of Orientation on the Legibility and Comfort of 3D-Printed Braille

“…While their proposed display was not 3D printed, the stimuli they used for their studies were. Minatani explored the usability of 3Dprinted braille for embossing tactile graphics, namely geographical maps [39]. They proposed a design pipeline and highlighted some of the practical obstructions they faced in their prototyping.…”

“…• H4 Participants are faster at reading the control print over the 3D-printed plates. Other explorations of 3Dprinted braille determined that FDM printing can produce lower quality braille than achievable with traditional embossers or high-grade professional printers [33,39].…”

Development of Tabletop Models of Internal Organs for Anatomy Learning of the Visually Impaired

“…For example, a service allowing the creation and use of tactile maps has been offered to the visually impaired and their caregivers [1][2][3]. Moreover, studies have been conducted on the use of 3D printers to help the visually impaired [4][5][6].…”
