ESUN PLA+ 1.75mm Light Brown 1kg Refill 3D Filament (PLA+175Q-C1R1)

Running out of filament mid-print can ruin hours of work. This 1kg refill coil of eSUN PLA+ in Light Brown keeps your printer fed without the waste of an extra spool. It’s the same tough, easy-to-print PLA+ you trust, now in a compact, eco-friendly refill format that fits standard spool holders once you mount it on a reusable spool.

Who is it for

Makers, hobbyists, and professionals who print frequently and want to reduce plastic waste and storage space. Ideal for those who already own a reusable spool or prefer to print their own. Perfect for functional prototypes, decorative items, and everyday prints where strength and a smooth finish matter.

Main features

• Refill coil without spool – less waste, lower cost, and easy to transfer to your own spool.
• PLA+ formula with enhanced toughness – higher impact resistance than standard PLA, yet still easy to print.
• Consistent 1.75mm diameter with tight tolerance (±0.03mm) for reliable extrusion and fewer clogs.
• Light Brown colour – a warm, neutral tone that hides layer lines and suits wood-like or earthy models.
• Low odour and low warping – prints cleanly on open-frame printers without a heated enclosure.
• Vacuum-sealed with desiccant – keeps filament dry and ready to print out of the box.

Tips

Before printing, transfer the refill coil onto a spool with side walls to prevent tangling. Store unused filament in a sealed bag with desiccant to maintain print quality. For best results, print a temperature tower to fine-tune within the recommended range. Light Brown PLA+ hides layer lines well, so you can use slightly larger layer heights for faster prints without sacrificing aesthetics.
