Abstract

1/1 resumo "processo de tratamento térmico de pós" a presente invenção refere-se a um método que compreende uma etapa de tratamento térmico de um pó à base de poliamida de modo a reduzir a diferença entre a temperatura inicial de rearranjo cristalino e a temperatura final de rearranjo cristalino. a invenção refere-se também a artigos obtidos utilizando pós que foram submetidos a esse tratamento, em particular por fusão seletiva de camadas de pó de polímeros, em particular prototipagem rápida por sinterização em fase sólida utilizando um laser.
