Reprapper Polypropylene PP Filament, Semi-Flexible Ultra Tough Filament 1.75mm 3D Printer Filament for 3D Printing (± 0.03mm) 2.2lb (1kg), 5pcs Build Sheet Included, Black

• 【Chemical & Moisture Resistant Performance】Crafted from high-purity polypropylene (PP) filament, finished prints boast reliable chemical stability against acids, alkalis and common solvents without deformation. With ultra-low water absorption, these chemical-resistant 3D prints stay stable in humid conditions, well-suited for functional components used in wet environments.
• 【Semi-Flexible & Lightweight Build】This lightweight 3D filament offers balanced semi-flexibility and low density. Printed PP parts endure repeated bending without cracking, great for living hinge 3D print projects, foldable fittings, sealed containers and handles. Its lightweight construction also works for drone parts, automotive accessories and lightweight engineering components.
• 【5pcs PP Build Sheet Included】Every 1KG spool includes 5 dedicated PP build sheets. They strengthen first-layer adhesion, reduce warping, lifting and peeling, and raise the success rate for all functional 3D printing applications.
• 【Optimized Print Guidelines】Filament diameter: 1.75mm with ±0.03mm tolerance for consistent feeding.Verified print settings: Nozzle 230–250℃, Hot Bed 70–90℃, Max Print Speed 80mm/s. An enclosed printer chamber is strongly recommended. This PP filament is incompatible with AMS and AMS Lite systems to prevent clogging and feeding errors. Once the vacuum seal is opened, filament may absorb ambient moisture during long storage. Pre-dry at 70℃ for 4 hours for smooth, consistent extrusion.
• 【Premium Vacuum Sealed Packaging】Each filament spool is individually vacuum-sealed with desiccant to block moisture and dust during storage. The moisture-proof packaging maintains the original toughness and print performance of this functional 3D filament. We provide professional after-sales support to resolve any product or printing concerns.
