摘要：

The use of the selective laser melting (SLM) rapid manufacturing technique for the fabrication of waveguide components is evaluated.The device under test (DUT) is a 50 mm long UG-387 flanged WR-10 waveguide. It is made of the Ti-6Al-4V alloy, which has a resistivity of 0.000178 Omega cm. The measured insertion loss of the DUT is 30.4 dB/m at 94 GHz. The insertion loss is in part due to the root mean square (RMS) surface roughness, which is 1.71 to 2.08 mu m on the outside, after abrasive blasting and chemical polishing. The DUT is benchmarked against a 50 mm long Agilent W11644A WR-10 standard thru section. (c) 2012 Wiley Periodicals, Inc.
