eSUN PLA-BASIC 1,75 mm sivý 1 kg refill 3D filament PLA-BASIC175H1R1

Running out of filament mid-print is frustrating, especially when you’re on a deadline or deep into a complex model. The eSUN PLA-BASIC 1.75mm Grey 1kg Refill solves that by giving you a full kilogram of reliable, easy-to-print PLA in a convenient spool-less coil, so you can keep your printer fed without the waste of an empty spool.

Who is it for

This refill is ideal for makers, hobbyists, and professionals who already have a reusable spool or spool holder and want to reduce plastic waste. It’s perfect for everyday printing, prototyping, educational projects, and functional parts that don’t require extreme strength or heat resistance.

Main features

• High-quality PLA (Polylactic Acid) with a consistent 1.75mm diameter and tight ±0.03mm tolerance for smooth, clog-free extrusion.
• Spool-less refill coil: simply mount it on your existing spool or holder to save plastic and storage space.
• Low odour and low warping, making it suitable for use in homes, offices, and classrooms.
• Biodegradable and derived from renewable resources, offering a more eco-friendly printing option.
• Vacuum-sealed with desiccant to keep the filament dry and ready to print.

Tips

Before printing, ensure your reusable spool is clean and properly secured to avoid tangling. Store the refill in a dry box or sealed bag with desiccant when not in use, as PLA can absorb moisture over time. For best results, start with a nozzle temperature of 200°C and adjust as needed for your printer and model.
