eSUN PLA+ Refilament 1.75mm 1KG Blue

Spoolless PLA+ Refill for FDM Printers

eSUN PLA+ Refilament arrives as a 1 kg coil of 1.75 mm blue filament without a built-in spool, so it must be used with a separate spool holder such as the eSUN or Bambu Lab designs. The material is an enhanced PLA+ formulation that delivers higher strength and toughness than standard PLA while keeping shrinkage and warping low for reliable indoor printing.

Upgrade from Standard PLA on High-Speed Machines

This refill targets owners of fast FDM printers who need consistent feeding at elevated speeds; the tight ±0.03 mm diameter tolerance and neat winding prevent tangles and nozzle clogs that often appear with basic PLA on machines like the Creality K1 series, Bambu Lab X1/P1 families or Voron 2.4. The jump is worth it when print speeds regularly exceed 100 mm/s and dimensional accuracy becomes critical.

Stable Extrusion During Long High-Speed Runs

Under sustained high-speed printing the filament maintains steady melt flow and layer adhesion thanks to its precise roundness and low moisture content from vacuum-sealed packaging with desiccant. Recommended parameters of 210–230 °C nozzle temperature, 45–60 °C bed temperature and 100 % fan speed keep performance consistent across multi-hour builds without the feed interruptions seen on looser-tolerance spools.
