Braille literature is expensive largely due to the specialized equipment required for its production. Unlike standard printing, which benefits from mass production techniques, Braille books require embossing machines. Braille embossers are significantly more expensive than regular printers, often costing thousands of dollars. The demand for Braille books is also relatively low compared to standard print books, making it difficult to achieve economies of scale, further driving up prices.
Braille books require a large amount of manual labor, specialized knowledge, and skills to produce. Transcribing a book into Braille can take a significant amount of time. Even with automated embossing machines, process lines require human intervention. Assembling and binding Braille books require careful handling due to their bulkiness.
Braille requires more space than printed text, leading to larger book sizes, increased paper usage, and higher material costs. Braille books are usually produced on higher-quality, thicker paper to accommodate the raised dots, which also increases the overall production cost. Unlike ink, which is inexpensive and easily mass-produced, the raised dots in Braille must be precisely formed using materials that maintain their shape and tactile readability over time.
We created some software to convert text into 3D printed molds.
Molds for a 250 page book costs ~375 USD and requires ~1500 printing hours (@6hr/page).
Molds for a 250 page book takes up ~1.5 GB of space.
Repeatably and efficiently emboss entire pages at a time.
While a 3D printer isn't exactly commonplace, 3D printing services are wide spread. Our mold approach offers a much more accesible and lower cost to entry in comparison to traditional embossing machines.
While our process is a good step in the right direction, we're currently investigating pressing automation to further lower overall cost. If you'd like to contribute, check out our github page.
Our mold approach expands access and performs well on a variety of media, ranging from traditional heavyweight braille paper, to cardstock, and even light weight copy paper.
With the low infrastructure cost of molds, pressing equipment, and the wide range of materials options, our approach enables the creation of low cost literature.
