What is 3D Braille

In the traditional sense, braille beads or professional braille engraving machines are used to make braille signs. In addition, we can also use another method of making Braille signs, namely 3D printing technology. We use 3D UV printing function. By setting the height of 3D printing, braille can be printed. Compared with using braille beads and braille engraving, it can make braille signs better and faster. At the same time, its price is cheaper than braille beads. The following is my braille logo printed by the company's 3D printer.
