Filament reel eSun PLA+ 1.75 mm Bone White, 1 kg, MPN PLA+P175BW1

eSun PLA+ 1.75 mm Bone White (1 kg) is an enhanced polylactic acid filament formulated for FDM/FFF 3D printers. The PLA+ material delivers improved toughness and reduced brittleness compared with standard PLA while maintaining good dimensional stability and surface finish. The bone-white shade provides a neutral, slightly warm white suitable for prototypes, visual models and finished parts where a clean, matte appearance is desired.

Advantages

The PLA+ blend increases impact resistance and layer adhesion compared with conventional PLA, reducing the likelihood of cracking or snapping in thin sections. It prints with predictable flow and low warping on most consumer and prosumer printers, producing fine detail and smooth outer surfaces. The neutral bone-white color masks internal lines and is suitable for post-processing options such as sanding, priming and painting.

Suitable for

• Functional prototypes and mechanical parts with moderate stress requirements
• Architectural models, figurines and display items
• Household fixtures, clips and non-load-bearing components
• Visual components intended for painting, priming or assembly

When it may not be suitable

This PLA+ filament is not intended for high-temperature or outdoor structural applications where continuous heat resistance or UV stability is required; prolonged exposure to heat or sunlight may deform or discolor the part. It is also not suited for parts that require extreme chemical resistance or flexibility comparable to TPU.

Key specifications

• Material type: PLA+ (enhanced polylactic acid)
• Nominal diameter: 1.75 mm
• Net weight: 1 kg spool
• Finish: matte, bone-white color
• Compatibility: FDM/FFF 3D printers with 1.75 mm filament path
• Typical printing properties: low warping, good layer adhesion, improved toughness

How to use

Load the filament onto a compatible 1.75 mm extruder following your printer manufacturer's instructions. Recommended print temperatures for PLA+ typically range between 200–220°C depending on printer and nozzle; start in the middle of this range and adjust for optimal layer bonding and surface finish. Use a print bed temperature of 40–60°C or a suitable adhesion method such as blue tape or a PEI sheet for best first-layer adhesion. Allow printed parts to cool gradually to reduce internal stress before removal.

What to consider before purchase

• Confirm your printer supports 1.75 mm filament diameter.
• Ensure your intended applications do not require high-temperature or UV-resistant materials.
• Check spool dimensions and weight capacity to verify it fits your spool holder.
• Consider required post-processing (sanding, priming, painting) for final appearance.

Usage recommendations

For consistent results, store the spool in a dry environment or sealed container with desiccant to limit moisture uptake. Calibrate extrusion multiplier and retraction settings to reduce stringing and improve detail. When painting, use a compatible primer to improve paint adhesion on the matte bone-white surface.
