We propose to image 10 gamma-ray bright and active blazars at 3 mm during the GMVA sessions in autumn 2016 and spring 2017. The same objects are monitored monthly with the VLBA at 7 mm to follow the time evolution of the jet and continuously at gamma-ray energies with Fermi as well as at intermediate wavebands with a wide variety of instruments. The primary goal is to relate the high-energy emission to physical conditions and structures in the mm-wave core region. We will accomplish this by total and polarized intensity imaging with angular resolution of about 50 microarcsec. The 3 mm images will (1) probe the core region where opacity and limited resolution make this difficult at 7 mm, (2) provide angular sizes of the most compact features for determining physical parameters, and (3) measure the polarization of the core and inner jet at 86 GHz, which can be compared with those at 43 GHz (VLBA).
