PP is a 3D printing consumable that uses PP as the main material, with the features of low density, high impact and chemical resistance. The raw material is homopolypropylene, the dimensional stability of the product is improved ddjusted by process and recipe, to prevent the models from warpping and cracking during printing. PP has excellent toughness and break elongation can reach 500%, commonly known as “Rubber folding 100 times”; PP has strong corrosion resistance and can withstand most organic solvents. Models printed with PP consumables also have high impact and corrosion resistance.
