US 2026/0109874 A1 · 3D PRINTABLE POLYPROPYLENE HOMOPOLYMER COMPOSITION, 3D PRINTED PRODUCTS COMPRISING THE SAME, AND METHODS THEREOF

Abstract

The present invention relates to 3D printable polypropylene (3DPP) homopolymer compositions. Specifically, the present invention relates to a 3DPP homopolymer compositions made by compounding, blending polypropylene with different hydrocarbon resins, fillers, compatibilizers and additives. Also, the invention relates to a method for preparing the 3DPP homopolymer compositions and products 3D printed using the 3DPP homopolymer compositions. The 3D printed products printed using 3DPP homopolymer composition exhibit improved 3D printability, interlayer adhesion, dimensional stability, reduced warpage with very high mechanical properties.
