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.

Discussion

  1. In my Introduction to MIS class I introduce 3D printing as part of the Future of Work. We discuss how 3D printing can and will transform how things get delivered.
    In class I walk through a simple example of planning a party using Walmart (I have one student be the “party planner” and other be the one for whom the party is planned). During the discussion I note how few choices we have and how inefficient things are, such as having to buy more plastic forks than there are people at the party.
    I then jump to how much better this would be if Walmart has 3D printers, and how customized we could be, and how Walmart could charge more (for the customization – “Happy 21st David” printed on the plates in my favorite color!) and how customers would prefer to pay more if they get better.
  2. Discuss potential applications of sound 3D printing, particularly focusing on how you can print THROUGH things (such as skin).
