3D printing method for braille books

Abstract

The invention relates to a 3D printing method for braille books. The method specifically comprises the following steps that S1, a three-dimensional model database with characters corresponding to braille projection points is established; S2, a braille book three-dimensional model is made; S3, the braille book three-dimensional model is sliced to obtain a G code file which can be recognized by a 3D printer; S4, the G code file obtained in the step S3 is transmitted to the 3D printer, a selective laser sintering forming machine is used for sintering printed braille pages, and entities of the braille book three-dimensional model are printed; S5, the printed braille book entities are subjected to post-treatment, so that the surfaces of the braille book entities are flatter and more smooth; and S6, the braille book entities are bound according to the page number sequence, and the braille book entities are bound into the braille books. The braille projection points manufactured by using the method are uniform and consistent, resistant to friction and capable of being repeatedly folded and used.

Description

technical field [0001] The invention belongs to the technical field of braille, and in particular relates to a method for 3D printing a braille book. Background technique [0002] The size, spacing and height of the convex points of Braille prints are fixed according to the physical and psychological characteristics of the blind's sense of touch. The shape of the convex points is generally hemispherical or parabolic. If the convex points are too small and the distance is too close, It affects the touch response speed of the blind, and if it is too large, it will exceed the most sensitive area of ​​the fingertips of the blind. Since Braille is often touched and squeezed, this also requires Braille to be more resistant to wear and tear. The traditional technology mainly obtains Braille by engraving or extrusion, which has problems such as high cost, low production efficiency, low adhesion, and bulky Braille books. [0003] In the prior art, the operation of making braille is...

Problems solved by technology

Traditional technology mainly obtains Braille by engraving or extrusion, which has problems such as high cost, low production efficiency, low adhesion, and bulky Braille books

[0003] In the prior art, the operation of making braille is complicated, and most of them are based on improving the printing device, which increases the production cost; the raised points of the braille produced have problems such as low adhesion and wear resistance
