1.75mm PLA FilamentNeatly wound premium PLA filament: the Sunlu 1.75 mm PLA filament is made from 100% pure raw material with guaranteed quality and without the addition of used materials to ensure the quality and stability of the filament. Each roll of PLA filament is neatly wound, even and flat, so that there are no clogging or sticking problems in 3D printing, making your printing process smoother, more fluent and more efficientTips: When the filament is not in use, remember to thread the Filament through the hole in the spool, or use the filament clip provided by our company to clamp the end of the filament before placing it, which can prevent tangling during winding!Recommended settings for beginners: if you are a beginner in 3D printing, the Sunlu PLA filament is ideal for you. We recommend you print with the 1.75 mm PLA filament at a 3D nozzle temperature of 200–210°C, a 3D printer bed temperature of 50–65°C and a 3D printer speed of 50–100 mm/s; you can easily start 3D printingCompatibility of the 3D filament spool: the Sunlu 3D printer spools have a broad compatibility. Spool diameter: 20.30 cm, spool width: 6.30 cm, spool hole diameter: 5.50 cm. The size of the Sunlu 3D printer filament spool means it is suitable for using with various FDM 3D printers, perfect for different types of 3D printingGood adhesion, harder than normal PLA: the Sunlu non-clogging premium 1.75 mm PLA filament has better flowability. The Sunlu 3D printer filament has a consistent diameter and roundness, less strand formation and warping problems, and the strong adhesion of the intermediate layer makes your 3D prints strongerRecyclable odourless PLA filament: the Sunlu PLA filament is made from non-used material and contains no substances harmful to humans and the environment. It also has a very low volatility and does not produce a pungent smell when printing, so you can 3D print in a pleasant environmentAbout SUNLU Campany: SUNLU was founded in 2013 as an integrated enterprise dedicated to providing users with premium 3D printing materials and supporting electronic products.
