SUNLU Filament Refill 1.75mm,Beige+Coffee Brown+Olive Green+Oak | petg Refill 4kg,Suitable for Bambu Lab Filament and SUNLU Reusable spools,Dimensional Accuracy +/- 0.02 mm

This PETG Refill Filament offers an economical solution for 3D printing enthusiasts who already own reusable spools. The 1.75mm diameter filament comes in a 4-pack of black spools, each containing 1kg of material with dimensional accuracy of +/- 0.02mm. This refill system is designed to work exclusively with empty reusable spools from compatible brands, reducing printing costs while maintaining quality. The PETG material combines enhanced toughness and high impact strength, making it ideal for creating durable parts that can withstand stress, bumps, and drops without cracking. The filament is engineered for smooth printing with reduced stringiness and no clogging issues. For optimal results, print at a nozzle temperature of 240-260C, bed temperature of 60-70C, and printing speed of 50-200mm/s. Each refill arrives in airtight vacuum packaging to ensure the filament remains moisture-free and maintains its quality until use. The refill design is compatible with reusable spools from multiple manufacturers and can also work with custom-printed spools, offering versatility for most 3D printer setups. This thermoplastic filament is suitable for creating sturdy, resilient items that require long-lasting performance and durability.
