Este trabalho aborda a digitalização 3D, modelagem e impressão de uma máscara tradicional das festas dos Caretos, uma cultura ancestral das terras de Trás-os-Montes, Portugal. Sendo um trabalho desenvolvido em parceria com o projeto “Cultura para Todos Bragança”. O objetivo principal é criar um recurso tátil 3D
acessível para pessoas com deficiência visual, permitindo que elas experimentem e compreendam o artefato histórico através do toque.
Na etapa de digitalização, foi utilizado o scanner 3D de luz estruturada para a captura com precisão dos detalhes da máscara. A nuvem de pontos resultante foi processada utilizando o software especializado para criar uma malha STL detalhada, preservando a textura e aparência originais da máscara.
Os softwares utilizados incluem o Colin3D, MeshLab e Meshmixer para processamento e edição de dados da digitalização. A máscara digitalizada foi então impressa em 3D, através da junção do software Ultimaker Cura com a impressora Ultimaker 3 Extended, garantindo uma reprodução fiel e precisa do artefato em formato físico.
Os resultados demonstram uma exatidão que atende às exigências do projeto. O recurso tátil final permite uma experiência inclusiva, capacitando pessoas com deficiência visual a explorar e entender a máscara de forma tátil.
Além disso, o estudo destaca a importância da acessibilidade em museus e do uso de tecnologias como scanners 3D e impressora 3D para promover a inclusão cultural. Este trabalho contribui para um ambiente mais igualitário e acessível, permitindo que pessoas com deficiência desfrutem da herança cultural de forma
significativa.
This work addresses the 3D scanning, modeling, and printing of a traditional mask from the Caretos’s Carnival, an ancestral culture from the Trás-os-Montes region of Portugal. It was developed in partnership with the "Culture for all Bragança" project. The main objective is to create a 3D tactile resource accessible to people with visual impairments, allowing them to experience and understand the historical artifact through touch. In the scanning phase, a structured light 3D scanner was used to accurately capture the details of the mask. The resulting point cloud was processed using specialized software to create a detailed STL mesh, preserving the original texture and appearance of the mask. The software tools used include Colin3D, MeshLab, and Meshmixer for processing and editing scan data. The digitized mask was then 3D printed using Ultimaker Cura software with the Ultimaker 3 Extended printer, ensuring a faithful and precise reproduction of the artifact in physical form. The results demonstrate good accuracy, meeting the project's requirements for precision. The final tactile resource enables an inclusive experience, empowering people with visual impairments to explore and understand the mask tactually. Additionally, the study emphasizes the importance of accessibility in museums and the use of technologies such as 3D scanners and printers to promote cultural inclusion. This work contributes to a more equitable and accessible environment, allowing people with disabilities to enjoy cultural heritage in a meaningful way.
