(a) Formulation process: (1) After mixing all of the components into a solvent, slurry is spread on a glass support by doctor blading technique and a film is finally obtained; (2) Composite film homogeneous pieces are introduced in an extruder. A typical 1.75 mm diameter 3D-printing filament is obtained and rolled; (3) Filament is introduced into a commercial FDM 3D-printer; DSC curves: (b) pure PLA, PLA/LFP wt% 40/60 and PLA/LFP/PEGDME500 with different amount of conductive additive (CSP); (c) comparison between film, filament, and 3D-printed disc for the 10%CSP sample.
