ESUN PLA+ 1.75mm Red 1kg Refill 3D Filament (PLA+175R1R1)

3D printing enthusiasts often struggle with brittle filaments that snap mid-print or produce parts with poor layer adhesion. The ESUN PLA+ 1.75mm Red 1kg Refill 3D Filament solves these issues by offering enhanced toughness and strength compared to standard PLA, while maintaining ease of use. This spool-less refill coil is perfect for users with reusable spools, reducing waste and cost. The vibrant red colour brings your creations to life, whether for functional prototypes or artistic models.

Who is it for

This filament is ideal for hobbyists, educators, and professionals who demand reliable, high-quality prints. It suits those who already own a reusable spool and want to minimize environmental impact without sacrificing performance. From detailed miniatures to durable mechanical parts, this PLA+ handles a wide range of projects.

Main features

• Enhanced PLA+ material: offers up to 10x the impact strength of standard PLA, with high toughness and low shrinkage.
• Spool-less refill coil: designed for use with reusable spools, reducing plastic waste and storage space.
• Precision diameter: 1.75 mm with a tolerance of ±0.03 mm ensures consistent extrusion and smooth printing.
• Vibrant red colour: produces eye-catching models with a smooth, glossy finish.
• Wide compatibility: works with most FDM 3D printers that accept 1.75 mm filament.
• Vacuum sealed packaging: includes desiccant to keep filament dry and prevent moisture-related printing issues.

Tips

Before printing, ensure the filament is dry; if it has absorbed moisture, dry it at 50–60 °C for 4–6 hours. Use a reusable spool with a minimum inner diameter of 90 mm and secure the coil to prevent tangling. For best results, print a temperature tower to fine-tune settings for your specific printer. Store unused filament in a sealed container with desiccant to maintain quality.
