Feature: 1. GOOD PERFORMANCE: Excellent PLA filament has strong toughness, low shrinkage and better adhesion between layers to meet functional printing needs. 2. FINE PROCESSING: The adaptive control system ensures that the diameter of 1.75 mm, the net weight of 1kg spool, and the dimensional tolerance is ±0.02mm. 3. HIGH ACCURACY: PLA is vacuum sealed with desiccant, without blockage and bubble, to protect the filament from moisture, achieve high accuracy printing. 4. NEAT ARRANGEMENT: Automatic mechanical winding, ensuring orderly arrangement, perfectly compatible with all common for FDM 1.75mm 3D printers. 5. PLASTIC SHELL: The plastic tray provides good protection for the printing filament, lightweight and durable, corrosion resistant and aging resistant. Specification: Item Type: 3D Printer Filament Material: PLA Printing Temperature: 190-210℃ Bottom Plate Temperature: 0-60℃ Printing Speed: 20-60mm/s Density: 1.25 ± 0.05g/cm³ Diameter: 1.75mm ± 0.02mm Water Absorption: 0.5% Tensile Strength: ≥ 60Mpa Bending Modulus: ≥ 60Mpa Elongation at Break: ≥ 3.0% Net Weight: Approx. 1KG / 2.2lb (without plastic tray) Wire Length: Approx. 340 meter / 1115.5ft Tray Size: Diameter: Approx. 198mm / 7.8in Inner Diameter: Approx. 58mm / 2.3in Height: Approx. 63mm / 2.5in. Package List: 1 x 3D Printer Filament Note: Please insert one end of the filament into the fixing hole to avoid being entangled after printing.The following methods can help extend the life of consumables:1. Do not open the package when not in use, and use it as soon as possible after opening;2. If it is not used for a long time after being unsealed, it is recommended to wrap it in a film bag to prevent it from getting damp;3. Store in a cool, dry and ventilated environment as far as possible;4. It is recommended to use unsealed consumables within 1 year.
