Broadband Millimeter Wave Characterization of 3-D Printed Materials

3D printing has significant potential advantages for the manufacture of millimeter wave systems including improvements in time to market and lower development costs. Key to these improvements is the ability to print high-quality materials with fine resolution and well understood, desirable dielectric properties in the millimeter wave regime. This paper reports the measured results on a wide variety of materials over a continuous spectrum of frequencies to 57 GHz.
