Adem\u00e1s, la posterior conservaci\u00f3n y transporte de los tejidos impresos a\u00f1aden complejidad adicional.<\/p>\n<p><center><\/center><\/p>\n<p>Para superar estos problemas, el equipo de Berkeley decidi\u00f3 paralelizar el proceso de impresi\u00f3n y dividirlo en etapas secuenciales. Es decir, en lugar de imprimir todo el \u00f3rgano de una vez, los tejidos se imprimen simult\u00e1neamente en capas bidimensionales, que luego son colocadas por un brazo rob\u00f3tico para crear la estructura tridimensional final.<\/p>\n<p>Este enfoque ya acelera el proceso, pero para reducir la muerte celular, las capas se sumergen inmediatamente en un ba\u00f1o criog\u00e9nico para congelarlas. Seg\u00fan el equipo, esto optimiza significativamente las condiciones para la supervivencia de los materiales impresos durante el almacenamiento y transporte.<\/p>\n<p>\u00abEn la actualidad, la bioprinters se utiliza principalmente para crear un volumen peque\u00f1o de tejido\u00bb, dice Boris Rubinsky, profesor de ingenier\u00eda mec\u00e1nica. \u00abEl problema con la bioprinters 3D es que es un proceso muy lento, por lo que no puedes imprimir nada grande, porque los materiales biol\u00f3gicos morir\u00e1n para cuando termines. Una de nuestras innovaciones es que congelamos los tejidos a medida que se imprimen, as\u00ed que el material biol\u00f3gico se conserva\u00bb.<\/p>\n<p>El equipo reconoce que este enfoque multicapa de la impresi\u00f3n 3D no es nuevo, pero su aplicaci\u00f3n en biomateriales es innovadora. Esto permite imprimir capas en un lugar y luego transportarlas a otro para su ensamblaje.<\/p>\n<p>Adem\u00e1s de crear tejidos y \u00f3rganos, esta t\u00e9cnica tiene otras aplicaciones, como en la producci\u00f3n de alimentos congelados a gran escala.<\/p>\n<p><center><div class=\"youtube-placeholder\" data-id=\"eXxBrvf9qJE\" onclick=\"loadVideo(this)\">\r\n        <img decoding=\"async\"
