Local activation of porosity in fused filament fabrication by in-nozzle physical foaming with supercritical CO2

Abstract Material extrusion of thermoplastics (fused filament fabrication, FFF) commonly deposits solid strands. Foams combine low density with functions such as damping and thermal insulation, making cellular strands a desirable extension of FFF. We demonstrate dissolution-assis...
