摘要： An inherently stable, throughflow-porous filter element for filtering foreign substances from a gas stream, comprising a filter body of plastic and having an inflow side and an opposite outflow side, wherein a surface filtration layer is formed on the inflow side, wherein the filter body has a three-dimensional support structure manufactured in an additive manufacturing process, said support structure having cavities through which gas can flow from the inflow side to the outflow side, and wherein the surface filtration layer at least partially fills the cavities of the three-dimensional support structure.
