eSUN PLA+ 1.75mm Bone White 1kg Refill 3D Filament PLA+175O-BW1R1

Struggling with brittle PLA prints that snap under stress? eSUN PLA+ in Bone White solves that by delivering up to 10x the impact strength of standard PLA, while keeping the easy printability you expect. This 1kg refill coil is perfect for makers who want professional-grade durability without the hassle of a spool.

Who is it for

Engineers, hobbyists, and educators who need tough, functional parts—brackets, enclosures, cosplay armor, or prototypes—will appreciate the enhanced mechanical properties. The bone white color offers a clean, matte finish ideal for painting or display models.

Main features

• PLA+ formulation: higher tensile strength (52 MPa) and elongation at break (29%) than standard PLA
• Spool-less refill coil: reduces plastic waste and works with reusable spools (check compatibility)
• Precision diameter: 1.75mm ±0.03mm tolerance for consistent extrusion
• Low odor and no bubbles: prints cleanly with minimal fumes
• Vacuum sealed with desiccant: keeps filament dry for optimal printing

Tips

For best results, dry the filament before use if exposed to humidity. Use a reusable spool or print a spool adapter to hold the refill coil securely. Store in a sealed bag with desiccant when not in use.
