ESUN PLA+ 1.75mm RGB Blue 1kg Refill 3D Filament (PLA+175P-U1R1)

ESUN's PLA+ refill in RGB Blue elevates standard PLA with a tougher, more reliable formula that prints with the ease of PLA but delivers strength approaching ABS. This spool-less refill is engineered for users who already own a reusable spool, cutting waste and cost while providing the same premium filament. The vibrant RGB Blue colour adds a dynamic, eye-catching finish to prototypes, artistic models, and functional parts alike.

Highlights

• Enhanced PLA+ formulation: higher tensile strength (≥55 MPa) and elongation at break (≥15%) than standard PLA, reducing brittleness and improving impact resistance.
• Precision 1.75 mm diameter with tight ±0.03 mm tolerance ensures consistent extrusion and reliable layer adhesion.
• Spool-less refill design: fits ESUN reusable spools (or compatible third-party spools), reducing plastic waste and storage space.
• Vibrant RGB Blue colour with a smooth, glossy finish that hides layer lines and enhances visual appeal.
• Low-odour, bubble-free, and tangle-free winding for hassle-free printing.
• Biodegradable material derived from renewable resources, aligning with eco-conscious workflows.

In daily use

Load the refill onto your reusable spool, feed it into any FDM printer, and print at 205–225 °C with a bed temperature of 25–70 °C. The filament flows smoothly with minimal stringing or warping, making it suitable for both detailed miniatures and large functional parts. Its low odour and reliable performance make it a favourite for home, office, and educational environments.
