Sunlu PLA+ Filament White — Sunlu PLA+ W 1.75 mm (compatible with FDM/FFF printers)

Sunlu PLA+ Filament White is a 1.75 mm PLA+ thermoplastic filament for FDM/FFF 3D printers. It combines improved mechanical toughness and reliable dimensional accuracy with a neutral white colour, making it suitable for both visual models and functional parts where a clean finish and greater durability are required.

Advantages

Sunlu PLA+ offers increased impact resistance and better interlayer adhesion compared with many standard PLA grades, delivering prints that resist damage while retaining a deep, consistent white tone. The filament is produced with tight diameter tolerance and low shrinkage to ensure stable feeding and predictable results during printing.

Suitable for

• Prototyping and concept models requiring a neutral white finish
• Functional parts and housings with moderate mechanical loads
• Detailed prints and decorative models where surface quality matters
• General-purpose FDM/FFF printing on 1.75 mm systems

When it may not be suitable

This PLA+ is not intended for high-temperature engineering applications; its heat deflection and softening temperatures are around the low-50s °C, so prolonged exposure to higher temperatures can deform printed parts. For applications requiring extreme impact resistance, high heat resistance, or significant flexibility, consider alternative materials engineered for those properties.

Key specifications

• Diameter: 1.75 mm with dimensional accuracy ±0.02 mm

• IZOD impact strength (X–Y): 3.5 kJ/m²; typical reported impact resistance up to 8 kJ/m² in optimized conditions

How to use

Load the 1.75 mm filament into any compatible FDM/FFF 3D printer and follow normal PLA print settings. Recommended nozzle temperatures vary by speed: 195–205 °C at 50–100 mm/s or 205–220 °C at 100–300 mm/s. Use a standard heated or unheated build plate according to your printer and adhesion method; bed temperatures are typically low for PLA. Ensure the spool feeds freely and that the filament path is free of obstructions to maintain consistent extrusion.

What to consider before purchase

• Confirm your printer supports 1.75 mm filament
• Check required part temperature resistance—PLA+ softens near 50–55 °C
• Plan print settings (nozzle temperature and speed) to match your printer and part detail

Usage recommendations

For best results, use stable extrusion settings and proper retraction values to reduce stringing. Store the filament in a dry environment or sealed container to avoid moisture uptake, and ensure the spool is wound evenly to prevent tangles during long prints.
