eSUN PLA+ 1.75mm Black 1kg Refill 3D Filament (PLA+175B1R1)

Makers and prototyping teams running high-volume FDM printing will appreciate this eSUN PLA+ refill coil. The 1 kg spool-free format drops straight onto a reusable master spool, cutting plastic waste and storage bulk while keeping the same reliable ePLA+ formulation. In black, it delivers crisp, professional-looking parts with a subtle sheen.

Key specifications

• Material: ePLA+ (enhanced PLA) with improved toughness and layer adhesion
• Diameter: 1.75 mm (±0.03 mm tolerance)
• Net weight: 1 kg (refill coil, no spool included)
• Print temperature: 205–225 °C
• Bed temperature: 25–60 °C (or off)
• Print speed: 40–100 mm/s
• Tensile strength: 52 MPa; elongation at break: 29%
• Density: 1.24 g/cm³; MFI: 2.7 g/10min (190°C/2.16kg)
• HDT: 52 °C
• Vacuum-sealed with desiccant; RoHS and REACH compliant

Why choose it

PLA+ bridges the gap between standard PLA and ABS. It prints as easily as PLA but offers significantly higher impact resistance and ductility, reducing cracked or shattered parts. The consistent 1.75 mm diameter and tight tolerance minimise clogs and extrusion issues, while the refill format lowers cost per kilogram and environmental footprint.

Ideal use cases

• Functional prototypes requiring snap-fits or repeated handling
• End-use parts like enclosures, brackets, and jigs
• Educational and hobby projects needing reliable, low-warp printing
• Cosplay props and display models where toughness matters

Good to know

Store the refill in its resealable vacuum bag with desiccant when not in use to prevent moisture absorption. For best results, use a direct-drive or well-tuned Bowden extruder and ensure your reusable spool matches the refill's inner diameter. Black ePLA+ hides layer lines well and can be sanded, primed, or painted for a finished look.
