Abstract Laser Sintering is a Rapid Prototyping (RP) technique used for the direct manufacture of solid objects layer by layer, with the aid of CAD models. In this investigation, a sintered bronze filter element was produced by the Direct Metal Laser-Sintering (DMLS) process and its performance data obtained and compared to more conventional elements. The tests showed that the elements had a narrow pore size distribution, a high pressure drop and a low contaminant holding capacity compared to a random fibre element of a similar rating. The ISO 16889 multi-pass beta = 1000 rating was 12 µm which was maintained up to the maximum test differential pressure of 10 bar. The element would be unsuitable for conventional filtration as its limited dirt holding capacity would mean a very short service life, but it could be suitable for Last Chance Filter applications or backwash and blowback applications. Further development would produce an optimum configuration.
