Electro‐Active Polymer Actuated Microfiltration Membranes: Design, Performance, and Particle Dynamics

open access: yesAdvanced Functional Materials, EarlyView.
The concept of foulant particle manipulation and detachment from active microfiltration membranes via voltage‐driven vibrations is introduced. Actuator components are initially integrated onto the filtration membranes using an airbrush spray printing technique.

Powder particle movement during Powder Bed Fusion

open access: yesProcedia Manufacturing, 2019
Abstract Powder Bed Fusion is a widely used technique to produce complex parts with different materials. In principle, a pre-placed powder layer is locally melted by a laser beam and thereby fused to the previous tracks and layers. This technique offers high flexibility at fast processing speeds.
