molding

Scientists have created “acoustic holograms” that can assemble matter into 3D objects, using just sound. The technique works with various types of particles and even living cells, allowing for a new kind of 3D printing that’s fast and contact-free.

Injection molding is the widely preferred method for shaping plastic medical components, but now a new type of machine promises to slash energy and materials costs. Ultrasion's Sonorous 1G uses ultrasound to produce highly targeted and efficient heating to melt its plastic base material.
