Futurizonte Editor’s Note: Printing with sounds? What would happen if you use the wrong sound or say the wrong word?
From the article:
There was a moment, after many trials and errors, that a team of engineering researchers at Concordia University realized they had achieved something remarkable.
It may not have looked like much from the outside: a few clicks on a computer screen, the whir of a 3D printer and a few bubbles solidifying in a plastic dish filled with liquid.
But this — at precisely 7:27 pm on April 27, 2018 — was the first time in the world that anyone had successfully printed a 3D object using sound waves.
“We were jumping, honestly, because we couldn’t believe that,” said Muthukumaran Packirisamy, professor of engineering and director of the optical-bio microsystems lab at Concordia. “It was a great moment for us … we had a lot of fun and parties after that!”
The team is now celebrating once again as its research, published last April in the journal Nature Communications, is being honoured as one of the top 10 scientific discoveries of the year by Québec Science magazine.
It’s a technology Packirisamy’s team believes could be used in the future for everything from repairing spacecraft and nuclear reactors, to printing medical devices directly into a patient’s body.
