Fully functional loudspeaker is 3-D printed

[Cupe]

Cornell researchers have 3-D printed a working loudspeaker, seamlessly integrating the plastic, conductive and magnetic parts, and ready for use almost as soon as it comes out of the printer.

It’s an achievement that 3-D printing evangelists feel will soon be the norm; rather than assembling consumer products from parts and components, complete functioning products could be fabricated at once, on demand.

The loudspeaker is a project led by Apoorva Kiran and Robert MacCurdy, graduate students in mechanical engineering, who work with Hod Lipson, associate professor of mechanical and aerospace engineering, and a leading 3-D printing innovator.

“Everything is 3-D printed,” said Kiran, as he launched a demo by connecting the newly printed mini speaker to amplifier wires. For the demo, the amplifier played a clip from President Barack Obama’s State of the Union speech that mentioned 3-D printing.
