Abstract

The article presents the studies and steps followed to optimize the 3D printing of an inclusive material, the “Adapted Multiplication Domino”. This material is a game that follows the same rules as a traditional domino, but with numerical representation at the ends of each piece with mathematical operations (multiplication and division), so that students can calculate, play, and fix math contents, which can be played by students with and without Visual Impairment. During the printing of the first prototype of this material, the printed pieces contained stringings (traces of filament in empty spaces of the piece), which made it difficult for blind students to read the braille operations. A literature review about problems in 3D printing was realized, using databases and platforms such as SciELO, Google Scholar, and Capes Periodical Portal, to be able to identify and solve the problem that was occurring. With that done, the complete game was printed and tested, to collect feedback, and based on that, making the necessary changes and obtaining a satisfactory and adequate result.
