Recientemente, investigadores de la Universidad de Missouri, en Estados Unidos, han desarrollado un m\u00e9todo que permite fabricar dispositivos complejos con una gran variedad de materiales \u2014entre ellos, pl\u00e1sticos, metales y semiconductores\u2014 utilizando una sola m\u00e1quina. El estudio, publicado recientemente en *Nature Communications*, describe un nuevo proceso de impresi\u00f3n 3D y l\u00e1ser para fabricar sensores multimateriales y multicapa, placas de circuitos e incluso tejidos con componentes electr\u00f3nicos.
Se espera que esta investigaci\u00f3n, denominada \u201cproceso de ensamblaje multimaterial de forma libre\u201d, revolucione el proceso de fabricaci\u00f3n de nuevos productos. Al imprimir sensores integrados en las estructuras, la m\u00e1quina puede crear dispositivos capaces de detectar condiciones ambientales, como la temperatura y la presi\u00f3n. Para otros investigadores, esto podr\u00eda significar disponer de un objeto de aspecto natural, como una roca o una concha, capaz de medir el flujo del agua de mar. Para el p\u00fablico en general, esta aplicaci\u00f3n sienta las bases t\u00e9cnicas para futuros dispositivos port\u00e1tiles que controlen la presi\u00f3n arterial y otros signos vitales.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n


En concreto, otras tecnolog\u00edas se quedan cortas en cuanto a la versatilidad de los materiales y a la forma de colocar con precisi\u00f3n piezas m\u00e1s peque\u00f1as dentro de estructuras 3D m\u00e1s grandes. El enfoque del equipo de investigaci\u00f3n resuelve estos problemas mediante t\u00e9cnicas especiales. Los miembros del equipo construyeron una m\u00e1quina con tres boquillas diferentes: una boquilla aplica un material similar a la tinta, otra utiliza un l\u00e1ser para tallar formas y materiales, y una tercera boquilla a\u00f1ade materiales funcionales adicionales para mejorar la funcionalidad del producto.
En primer lugar, la estructura b\u00e1sica se fabrica con filamentos habituales de impresi\u00f3n 3D (como el policarbonato, un termopl\u00e1stico transparente). A continuaci\u00f3n, se utiliza un l\u00e1ser para convertir determinadas partes en un material especial denominado \u00abgrafeno inducido por l\u00e1ser\u00bb y colocarlo exactamente donde se necesita. Por \u00faltimo, se a\u00f1aden m\u00e1s materiales para mejorar la funcionalidad del producto final.
\u201cEste trabajo ha contado con el apoyo del Programa de Fabricaci\u00f3n Avanzada de la Fundaci\u00f3n Nacional para la Ciencia (NSF), y el programa I-Corps\u2122 de la NSF ha proporcionado financiaci\u00f3n para explorar su comercializaci\u00f3n. El programa I-Corps est\u00e1 ayudando al equipo de investigaci\u00f3n a identificar los intereses y las necesidades del mercado\u201d, afirm\u00f3 Jian \u201cJaven\u201d Lin, profesor asociado de ingenier\u00eda mec\u00e1nica y aeroespacial de la universidad. \u201cEn este momento, creemos que otros investigadores se interesar\u00e1n por ello, pero estamos convencidos de que, en \u00faltima instancia, beneficiar\u00e1 a las empresas. Reducir\u00e1 el tiempo necesario para crear un prototipo de un dispositivo, lo que permitir\u00e1 a las empresas fabricarlos internamente\u201d. Es la primera vez que se utiliza este proceso, y abre nuevas posibilidades, afirm\u00f3 Bujingda Zheng, primer autor del estudio y estudiante de doctorado en ingenier\u00eda mec\u00e1nica en la Universidad de Missouri. \u201cEstoy muy ilusionado con este dise\u00f1o. Una de las principales ventajas es que los innovadores pueden centrarse en el dise\u00f1o de nuevos productos sin preocuparse por c\u00f3mo fabricar los prototipos. Esto abre la posibilidad de mercados completamente nuevos\u201d. Lin afirm\u00f3 que tendr\u00e1 un amplio impacto en los sensores port\u00e1tiles, los robots personalizables, los dispositivos m\u00e9dicos y mucho m\u00e1s.
En la actualidad, la fabricaci\u00f3n de estructuras multicapa, como las placas de circuitos impresos, es un proceso engorroso que implica m\u00faltiples pasos y diversos materiales. Estos procesos son costosos, requieren mucho tiempo y generan residuos perjudiciales para el medio ambiente. La nueva tecnolog\u00eda no solo es m\u00e1s respetuosa con el planeta, sino que adem\u00e1s se inspira en los sistemas de la naturaleza. Por ejemplo, seg\u00fan explic\u00f3 Zheng, las anguilas el\u00e9ctricas tienen esqueletos y m\u00fasculos que les permiten moverse. Tambi\u00e9n cuentan con c\u00e9lulas especializadas capaces de generar hasta 500 voltios para ahuyentar a los depredadores. Estas observaciones biol\u00f3gicas han inspirado a los investigadores a desarrollar nuevas formas de crear estructuras tridimensionales con aplicaciones vers\u00e1tiles, pero otros m\u00e9todos emergentes presentan limitaciones.<\/p>","protected":false},"excerpt":{"rendered":"
