Abstract

ESTRUTURA TRIDIMENSIONAL AUXÉTICA UTILIZADA EM APLICAÇÕES DE MANUFATURA ADITIVA. A presente invenção refere-se a uma estrutura auxética (NPR) que inclui uma pluralidade de folhas onduladas de interseção vertical, cada folha ondulada exibindo uma razão de Poisson negativa, cada folha ondulada intercepta duas folhas onduladas adjacentes criando uma estrutura tubular retangular e tendo uma porção de cada folha ondulada se projetando para fora a partir de sua intersecção com uma folha ondulada adjacente, a amplitude de cada ondulação na pluralidade de folhas recortadas é tal que nenhuma superfície saliente da folha recortada excede um limite de ângulo para impressão sem estruturas de suporte.
