Contenido principal del artículo
Objetivo: En nuestro trabajo presentamos el desarrollo de texturas superficiales con diferentes geometrías fabricadas por manufactura aditiva. Metodología: Los sustratos con diferentes texturas superficiales son diseñados por medio de programas asistidos por computador (CAD). La fabricación de las diferentes superficies se realiza capa a capa, en un solo proceso, por medio de la técnica de estereolitografía láser (SLA), directamente desde los archivos CAD. Resultados: Las superficies de los sustratos fueron evaluadas mediante ensayos ópticos con el objetivo de medir la topografía de las superficies, validar el acabado superficial y controlar los métodos de fabricación a través de las estrategias de medición en diferentes perfiles. Conclusión: En este estudio mostramos que las texturas superficiales impresas presentaron una reducción de los valores de medidas de longitud, volumen y masa en comparación con la definida en el diseño.
