How to 3D print Braille books

Abstract

The present invention relates to a method for 3D printing braille documents, which specifically includes the following steps: S1, establishing a three-dimensional model database corresponding to characters and braille raised points; S2, making a three-dimensional model of a braille document; S3, performing slice processing on the three-dimensional model of a braille document , obtain the G code file that can be recognized by the 3D printer; S4, transfer the G code file obtained in step S3 to the 3D printer, use the selective laser sintering molding machine to sinter the printed Braille single page, and print out the three-dimensional model of the Braille book Entity; S5. Post-processing the printed Braille book entity to make the surface of the Braille book entity smoother; S6. Binding the Braille book entity according to the order of page numbers to form a Braille book. The raised points of the Braille made by the invention are uniform, friction-resistant, and can be folded and used repeatedly.

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.

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
