Ultrasonic atomisation provides an alternative to conventional gas atomisation for powder production for additive manufacturing. It is ideally suited to production of small batches, offering users the freedom to produce powders of virtually any composition, using any feedstock you can obtain to produce spherical powders of narrow particle sizings with excellent flow characteristics. rePOWDER is the perfect solution for those who only need to produce small volumes of powder and those wishing to create and refine powder compositions.

Compared to gas atomisation, ultrasonic atomisation is better suited to production of small quantities of metal powders, offering a more economical alternative, including resource and time efficiencies. It’s modular design enables the use of different heating modules depending on the melting point of the feedstock, with the ability to produce metal powders from grams to kilograms.

How Does Ultrasonic Atomisation Work?

Feed metal is melted using arc/plasma (up to 3500°C) or induction (up to 1300°C) depending on its melting temperature. The molten metal is dropped onto a vibrating surface causing ejection of tiny metal droplets. These droplets are solidified in an inert environment, resulting in formation of the metal powder.

The size of the metal droplets and hence metal powders can be controlled by the ultrasonic vibration frequency, with higher frequencies yielding smaller powders.
