Ideal filters have a maximised open area for increased filtration efficiency, but this can compromise the overall strength of the filter. Traditionally, metal filters are made from perforated plate, mesh and wedge wire. The capabilities of selective laser melting (SLM) additive manufacturing (AM) technology offers creation of 3D filter designs that have combined filter and support portions with maximised open area and inherent strength for operational industrial processes. This advance in processing for the manufacture of filters also delivers further benefits in filtration efficiency saving end-users energy costs. The combination of three separate parts into a consolidated unit has significantly reduced time and cost of production of wedge wire filters and removed expensive tooling requirements. AM technology allows the production of innovative metal filters as a competitive manufacturing process and delivers high value products for customers.
