The AconitySIEVE extends our equipment portfolio towards powder preparation for the LBM process. The sieving equipment is designed for fast and precise processing of powder material.

The ultrasonic generator with variable amplitude enables high throughput rates at low noise generation.

The system is easy to clean and can be quickly adapted to different powder materials.

The scope of applicable materials can be maximized with different mesh sizes, an optional inertization unit and flexible handling system.


AconitySIEVE extends Aconity's device portfolio towards powder preparation for the L-PBF process. The sieving unit is suitable for fast and precise classification of powder materials - also under inert gas atmosphere.
