Abstract

The study, design and development of a low-cost digital braille printer is boarded with a transdisciplinary approach. The main challenge was focused on reducing significantly the high cost of this type of printers and their printing services. This context is aggravated with the low commercialization of these products in the country, a factor that makes the access of these tools -that are essential to much of the low and middle sectors of the Argentine social structure- even more difficult. An interdisciplinary group of teachers, graduates and students of the careers of industrial design and informatics degree from the National University of La Plata, developed the design and prototype of a braille printer. The work was carried out according to the principles of Gandhian Engineering, based on the reuse of ink-jet printers. The project consists of the design, development and generation of a low-cost Braille printer, produced locally, which prioritizes the use of nationally manufactured components for assembly. To achieve this, an electronic and electromechanical system was designed and manufactured to adapt any Inkjet printer to the objectives of the project, enabling the recycling of obsolete printers. This means, it is proposed to resolve through the use of text printers, applying technical knowledge of computer science and industrial design, to adapt the technological components to the Braille lexicon printer. They also developed, on the one hand, software that controls the printer and allows its use in a simple and accessible way. On the other hand, the hardware and external components were adapted with 3D printing technology and thermoforming, producing a housing that contains the entire printer. Finally, a systematization of the assembly process of the printer prototype was carried out, making it possible to replicate it. Using methodologies of Gandhian Design, a prototype and two alternative proposals of carcasses were obtained. The main objective, which guided this work, was that blind people can access low-cost braille printers promoting by this a favorable impact on the cultural development of their daily lives.
