Despite the advantages that selective laser sintering (SLS) offers in terms of material
availability, many materials have yet to be explored for feasibility and even fewer are
available on a commercial basis. This paper presents initial investigations for one such
material, borosilicate glass, which could be of particular interest to filter manufacturers
because it presents an attractive alternative to the conventional, time-consuming way of
producing filters of various porosity classes. Process results are presented including a
determination of the optimal parameter window and the effect of processing parameters on the
density and surface quality. The effects of thermal post-processing and the inclusion of an
additive are also discussed.Mechanical Engineerin
