Abstract

En el presente documento, se divulga un método de fabricación de una lente óptica utilizando una impresora 3D y sobremoldeo por inyección. El método incluye la obtención de un soporte termoplástico (TP) transparente con al menos una superficie lisa, la impresión, mediante una impresora 3D en el lado opuesto a la al menos una superficie lisa del soporte TP transparente, de al menos una capa transparente utilizando un filamento termoplástico, teniendo cada capa transparente una propiedad de filtrado de luz predeterminada, formando de ese modo una capa funcional; y la ejecución de un procedimiento de sobremoldeo por inyección para unir por fusión la capa funcional a un sustrato termoplástico, formando de ese modo la lente óptica.
