MT Magnesium Titanate Ceramic

The combination of high dielectric constant and low dielectric loss make MT Ceramic suitable for millimeter wave applications such as antennas, wave guides, and other electronic components. 

Key benefits: 

  • Dielectric properties (high constant, low loss) 100x lower than plastic alumina

Target applications/industries: Communications and aerospace, waveguides,
mm wave electronic components (sensors, radar cover, antenna, wave tuning components)

As a current BMF customer, we’ve been thrilled with the performance of our microArch S130 to support our work in micro-printing ceramics - providing the resolution, accuracy and precision necessary for our parts. As the first customer of the new microArch S230, the next generation 2µm system, we are excited to utilize the enhancements of the platform to increase our part capacity with the larger build volume and speed up our printing times. We are looking forward to continuing to work with the BMF team and their line of micro-precision 3D printers to support our micro part needs.
