This made me dizzy trying to envision the process...
Holographic direct sound printing could make polymer additive manufacturing 20x faster
Acoustic holograms cause extremely rapid polymerization by inducing regional cavitation bubbles.
A novel method of 3D printing that uses acoustic holograms could yield an order-of-magnitude improvement in polymerization-based additive manufacturing (AM). According to researchers at Concordia University, the new approach is both quicker than existing methods and capable of making more complex objects.
The process, called holographic direct sound printing (HDSP) builds on a method introduced in 2022 that described how sonochemical reactions in microscopic cavitations regions create extremely high temperatures and pressure for trillionths of a second to harden resin into complex patterns.
