Researchers at Concordia have developed a novel method of 3D printing that uses acoustic holograms. And they say it’s quicker than existing methods and capable of making more complex objects. The process, called holographic direct sound printing (HDSP).
Now, by embedding the technique in acoustic holograms that contain cross-sectional images of a particular design, polymerization occurs much more quickly. It can create objects simultaneously rather than voxel-by-voxel.
