Esun PLA+ 1,75 mm blauw 1 kg navulfilament

PLA+ filament in blue, engineered for high-strength 3D printing with a 1.75 mm diameter and 1 kg net weight. This spool-less refill delivers exceptional layer adhesion and impact resistance, making it ideal for functional prototypes and durable parts. The vibrant blue colour remains consistent across prints, while the low-odour formulation ensures a comfortable printing environment. Vacuum-sealed with desiccant to preserve material quality from factory to printer.

Advantages

PLA+ offers superior mechanical properties compared to standard PLA, with a tensile strength of ≥50 MPa and elongation at break of ≥15%. The tight diameter tolerance of ±0.03 mm guarantees smooth, clog-free extrusion. The refill format reduces plastic waste and is compatible with reusable spools, supporting sustainable printing practices. Its low odour and 100% bubble-free composition enhance print reliability and user comfort.

Suitable for

• Functional prototypes requiring higher impact strength
• Durable end-use parts and mechanical components
• Educational projects and hobbyist printing
• Models needing a vivid, consistent blue finish
• Users with reusable spool systems seeking eco-friendly options

Recommendations

For best results, print with a nozzle temperature of 210 °C and a bed temperature of 55 °C on a clean build surface. Store the refill in a dry, cool place, preferably in a sealed container with desiccant when not in use. Use a reusable spool with a secure locking mechanism to prevent tangling during printing. This filament pairs well with direct-drive extruders and all-metal hotends capable of maintaining stable temperatures.
