Radiophysicists are developing a new ultrasonic 3D printing method
TSU’s radiophysicists have created an installation for levitation of small particles, in particular, foam plastic, in an acoustic field. With this technology, they will develop a new method of ultrasonic 3D printing by 2020 that can be used for chemically aggressive solutions or substances heated to high temperatures.
The TSU installation consists of an anechoic chamber covered with wave absorbers and emitters. The particles are suspended in a stream of acoustic waves (40 kHz), and depending on the power, their number and size can be increased. With a specially created program, the levitated particles can be controlled and moved from side to side.
