An adaptable sintered filter element that is manufactured by 3D printing will be introduced this month at the Powtech exhibition (September 27–29; Nuremberg, Germany). Developed by Herding GmbH Filtertechnik (Amberg, Germany; www.herding.com), Omikron is an adaptable sinter-plate filter element that can be tailor made to the desired size and shape (photo), in quantities as low as a single element.

Up to now, the company’s conventional sinter-plate filters have been focused on a linear lamella geometry. Although these elements are available in a wide variety of dimensions, there had been no change to the linearity of the basic geometry determined by the sinter shape. The new Omikron filter element eliminates the geometric limitations of standardized shapes, and, for the first time, makes it possible to adapt geometries to the intended use and structural conditions.

Smaller sizes are also possible. Before the introduction of Omikron, Herding’s smallest filter element had a filtration area of 0.7 m², but thanks to the new production process, significantly smaller filter elements can now be manufactured, which is beneficial for biotechnology applications.

Both the basic body and the coating of the filter elements are produced from polyethylene (PE), and the filter element complies with V(EG) 1935/2004, VO(EU) 10/2011, as well as U.S. Food and Drug Admin. (FDA) requirements for applications in the food and pharmaceutical sectors. Further product-specific features are the possibilities to wash and sterilize the filter element according to industrial standards, the company says.
