    Different lengths of WR3 (220ââ?¬â??330 GHz) and WR10 (75ââ?¬â??110 GHz)\nwaveguides are fabricated through direct metal laser sintering (DMLS). The losses\nin these waveguides are measured and modelled using the Huray surface roughness\nmodel. The losses in WR3 are around 0.3 dB/mm and in WR10 0.05 dB/mm. The\nHuray equation model is accounting relatively good for the attenuation in the WR10\nwaveguide but deviates more in the WR3 waveguide. The model is compared to finite\nelement simulations of the losses assuming an approximate surface structure similar\nto the resulting one from the DMLS process.
