We've had customers use our prototypes for fluid applications. If you're
talking plastics, the SLS process can be used, but must first be coated to
seal porosity. We had one customer use us to make a water valve part for
life testing. The valve operated in excess of 7000 cycles with approx.
100+p.s.i. water pressure and flow.
