Materials Science: Overcoming Warpage in Polypropylene 3D Printing Filaments

While polypropylene is one of the most widely used industrial polymers in the world due to its low cost, chemical resistance, and toughness, it historically presented severe challenges in fused filament fabrication (FFF) and powder bed fusion (PBF) 3D printing technologies. Unmodified, neat PP is highly semicrystalline, which causes significant volumetric shrinkage during the cooling and...
