Concordia University researchers have introduced a new approach to 3D printing that utilises acoustic holograms. This breakthrough method, known as holographic direct sound printing (HDSP), could offer faster and more complex printing capabilities than conventional techniques, potentially transforming applications across numerous sectors.

The proportion of older adults with age-related vision loss is estimated to be as high as one in three over the age of 50. In Canada, that's roughly 3.6 million people. Many of these individuals turn to adaptive devices designed to magnify objects and text, but these devices can be prohibitively expensive, uni-functional and bulky. Enter the iPad: a technological device that's relatively cheap, serves many purposes, is smaller than most books, an...
