Abstract

a invenção é um método para controlar a atividade de duas fontes de radiação luminosa (2, 3) pertencentes a uma máquina de estereolitografia (1) e adequadas para agir no nível de uma porção (104) de uma área de sobreposição (101) definida na superfície de trabalho (100) da máquina de estereolitografia (1) para a produção de um objeto tridimensional (200) através de estereolitografia. para cada uma das linhas (210) com comprimento genérico l que definem cada camada (201) do objeto tridimensional (200) dentro da porção (104), o método provê a ativação de: - uma primeira fonte de radiação luminosa (2) para uma primeira seção (211) da linha (210) tendo comprimento x; - uma segunda fonte de radiação luminosa (3) para a segunda seção restante (212) da linha (210) tendo comprimento y, em que o valor x da primeira seção (211) é selecionado dentro do intervalo 0 < = x < = l e em que v é calculado como igual a l - x.
