Filament spool eSun PLA+ 1.75 mm, Grey, 5 kg

eSun PLA+ 1.75 mm filament in grey on a 5 kg spool is a modified polylactic acid material formulated for FDM/FFF 3D printing. Compared with standard PLA, PLA+ offers improved toughness and better layer adhesion while retaining the ease of printing and lower warping typical of PLA. The 1.75 mm diameter is compatible with most consumer and prosumer desktop printers that accept 1.75 mm filament, and the large 5 kg spool reduces the need for frequent filament changes during extended prints.

Advantages

This PLA+ filament combines the dimensional stability and low-warp characteristics of PLA with enhanced impact resistance and improved interlayer bonding. It prints reliably on a wide range of printers, requires no special storage beyond dry conditions, and generally produces smoother surfaces and fewer print failures than some standard PLA grades. The grey color provides neutral, easy-to-paint or post-processable parts for prototypes and functional components.

Suitable for

• Prototyping and concept models
• Functional parts and mechanical components with moderate stress
• Household items, fixtures and custom enclosures
• Visual models and parts intended for painting or finishing

Key specifications

• Material: Modified polylactic acid (PLA+)
• Nominal diameter: 1.75 mm
• Spool weight: 5 kg net filament
• Color: Grey
• Recommended printing technology: FDM/FFF
• Typical characteristics: improved toughness and layer adhesion, low warpage

How to use

Load the 1.75 mm filament into any compatible FDM/FFF extruder following your printer manufacturer's instructions. Typical print settings for PLA+ start with a nozzle temperature around 200–220 °C and a heated bed temperature near 50–60 °C, but adjust temps and print speed according to your printer, nozzle size and part geometry. Ensure the filament spool can rotate freely and keep the filament path free of sharp bends or snags. Store the spool in a dry place or sealed container with desiccant when not in use to preserve print quality.

Usage recommendations

For best results, calibrate extrusion and retraction settings, use a moderate print speed to benefit from the improved layer adhesion, and consider a heated bed or adhesion aid for larger flat prints. If post-processing is planned, the neutral grey surface accepts paints and fillers well; sanding between coats improves finish. Avoid prolonged exposure to humid conditions to maintain consistent extrusion and mechanical properties.
