    Abstract
    The present study focuses on the preparation and characterization of a poly/poly blend for application in additive manufacturing using fused filament fabrication. Polymer miscibility was evaluated using differential scanning calorimetry analysis and Fourier transform infrared analysis. The results confirmed the full miscibility of PEEK and PEI at all compositions. Seen as the best compromise between mechanical properties and glass transition temperature, a 70/30 wt/wt% PEEK/PEI blend was extruded into filaments for use by FFF. Nozzle temperature, layer orientation, and layer...
