In addition , their hygromechanical behaviour linked to moisture effect is investigated through sorption , hygroexpansion and mechanical properties characterization on a wide range of relative humidity ( 10–98 % Relative Humidity RH ) .The printing process induces an original microstructure with multiscale singularities ( intra/inter beads porosity and filament loop ) .
