Se describen materiales no tejidos tridimensionales y métodos de fabricación de tales materiales. En una modalidad, un método puede incluir proporcionar una trama precursora que incluye una pluralidad de fibras y transferir la trama precursora a una superficie de conformación que tiene una pluralidad de agujeros de conformación. El método también puede incluir dirigir una pluralidad de corrientes de fluido a presión del fluido de enredado en una dirección hacia la trama precursora sobre la superficie de conformación para mover al menos algunas de las fibras hacia la pluralidad de agujeros de conformación para crear una trama enredada por fluido. El método puede incluir además retirar la trama enredada por fluido de la superficie de conformación de manera que al menos algunas de las fibras movidas hacia la pluralidad de agujeros de conformación proporcionan una pluralidad de nodos. La pluralidad de nodos puede tener un valor de anisotropía mayor que 1.0 según se determina por el Método de prueba de análisis de nodos.
