Abstract
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.
Claims8
Filter for cleaning fluids, having a main body made of polyethylene particles which are bonded to each other by means of a generative manufacturing method in such a way that a predefined macrostructure and microstructure is established, wherein the main body has regions in which the porosity is adjusted differently in a targeted manner, wherein
- the filter has a greater porosity at its surface than in an interior of the filter and/or has a coarse-grained surface structure.
