Using Sound Waves To 3D-Print Objects

When an object is 3D printed, a computer processes an object’s design and sequentially “prints” each of its layers on top of one another. In a new form of 3D printing from the Max Planck Institute for Medical Research and Heidelberg University, the printer materializes objects by manipulating sound waves, a “touch-less” version of 3D printing. Just as sound can have an impact on the …

Using Sound Waves to Triple Battery Life and Reduce E-Waste

Researchers at Melbourne, Australia’s RMIT University developed an acoustic device that can remove performance-inhibiting rust from batteries, tripling their lifespan and, hopefully, reducing how frequently they are discarded. The researchers used MXene, a nano-material that holds promise as an alternative to lithium batteries, yet is prone to rust. They discovered that high-frequency sound waves cause the MXene battery to vibrate with enough force for the …

Scientists Succeed in Growing New Bones Using Sound Waves

Using high-frequency sound waves, scientists at the Royal Melbourne Institute of Technology in Australia have managed to grow new bones out of stem cells. Having spent over a decade investigating how sound interacts with different materials, researchers developed a sound wave-generating device that can manipulate cells and fluids. “We can use the sound waves to apply just the right amount of pressure in the right …
