THE INFLUENCE OF MICROSTRUCTURE OF 3D PRINTING ON TACTILE PERCEPTION OF HUMANS
Original language description
Braille script is one of the most important communication tools for visual disable people. This script is a group of six points, systematically composed into Braille cell representing each letter or number in alphabet. It has been used for marking medicine, entrances or exits and other items. The Braille script can be made from different materials, usually paper or metal desks applied to the required surfaces. In this work, Braille cells were applied by multi layered 3D printing directly to the textile surface taking into consideration the right preparation of substrates. 3D printing is created on basic cotton canvas in two variants: rough porous printing with micro roughness and smooth printing with minimal changes in roughness. A comparative evaluation for these two kinds of 3D printing was carried out to measure the micro roughness and the height using electron and confocal microscopy. Then, a qualitative study for the ability of blind people with different defects of visual impairment to recognize and read the printed Braille script was done. Blind people are using mechanoreceptors, especially Vater Pacini corpuscle, to provide information about the texture, pressure and vibration. Results of this study can define future modifications to examine influence of micro and nano structures on the tactile properties of 3D printed Braille scripts and other applications.
