Abstract (en)
[origin: WO2020049020A2] The invention relates to a filter (1) for cleaning fluids, having a main part (2) consisting of polyethylene particles (3) that have been bonded to each other by means of a generative manufacturing process such as to obtain a predefined macro- and microstructure, the main part (2) having regions in which the porosity is deliberately adjusted to varying values. The invention also relates to a method for producing a filter (1), the filter being generatively manufactured by selective laser sintering of polyethylene particles (3). The invention finally relates to a method for ensuring fluid flow.
