ETH researchers from the Functional Materials Laboratory have developed a silicone heart that beats almost like a human heart

Los investigadores de ETH del Laboratorio de Materiales Funcionales han desarrollado un corazón de silicona que late casi como un corazón humano.

The soft artificial heart was created from silicone using a 3D-printing, lost-wax casting technique; it weighs 390 grams and has a volume of 679 cm3. “It is a silicone monoblock with complex inner structure,” explains Cohrs. This artificial heart has a right and a left ventricle, just like a real human heart, though they are not separated by a septum but by an additional chamber. This chamber is in- and deflated by pressurized air and is required to pump fluid from the blood chambers, thus replacing the muscle contraction of the human heart.

El corazón artificial suave se creó a partir de silicona utilizando una técnica de impresión en 3D, de cera perdida; Pesa 390 gramos y tiene un volumen de 679 cm3. "Es un monobloque de silicona con estructura interna compleja", explica Cohrs. Este corazón artificial tiene un ventrículo derecho y un ventrículo izquierdo, igual que un corazón humano real, aunque no están separados por un tabique sino por una cámara adicional. Esta cámara es introducida y desinflada por aire presurizado y se requiere para bombear fluido de las cámaras de sangre, reemplazando así la contracción muscular del corazón humano.

Great post. 3D printing is gonna change the world ! Upvoted and resteemed ! I look forward to more cool stuff ! Happy to be following ya !

Technology is unbelievable these days @jesusrc1 compared to 100 years ago. You can get a descent 3D printer for around £200 in kit form and build yourself. Thanks for sharing.
