eSUN PLA+ Refilament 1.75mm Grey 1kg

PLA+ Refilament for FDM printers

eSUN PLA+ Refilament is a spoolless 1.75 mm filament designed for FDM 3D printers. It suits makers who want a high-speed material without managing empty spools. The Grey PLA+ formulation delivers higher strength and toughness than standard PLA for functional parts. Buyers who need a ready-to-mount spool or a different diameter should look elsewhere.

Diameter tolerance ±0.03 mm

The single specification that decides fit is the 1.75 mm diameter held to a ±0.03 mm tolerance. This tight control ensures consistent feeding and stable extrusion on compatible machines. The spoolless coil requires a separate spool holder such as the eSUN or Bambu Lab models. Printers that cannot accept 1.75 mm material or lack a holder for refill coils cannot use this product.

High-speed behaviour up to 100 mm/s

Under sustained load the filament maintains consistent flow at printing speeds of 40-100 mm/s with the fan at 100 %. Recommended nozzle temperature is 210-230 °C (215 °C typical) and bed temperature 45-60 °C. Low shrinkage and minimal warping prevent deformation during long prints. Vacuum-sealed packaging with desiccant preserves dryness for reliable layer adhesion over extended sessions.
