Filament Sunlu PLA+ 2.0 (Green) — PLA+ 1.75 mm compatible for FDM 3D printers

Sunlu PLA+ 2.0 filament in green is a 1.75 mm PLA+ material for FDM 3D printers designed for general-purpose models, prototypes and functional parts. Version 2.0 increases material flow versus standard PLA for a more consistent feed and reduced risk of nozzle clogging. With a diameter tolerance of ±0.02 mm and improved toughness, this filament aims to deliver reliable prints with lower warping and smoother operation at higher speeds.

Advantages

Sunlu PLA+ 2.0 combines the user-friendly handling of PLA with enhanced durability similar to easy-to-print ABS variants. The material offers higher impact resistance, crack resistance, and dimensional stability, while allowing faster printing speeds. Consistent extrusion and low warping tendency contribute to more reliable prints and a better surface finish.

Suitable for

• Prototyping and proof-of-concept models
• Hobbyist prints and decorative models
• Functional parts that require improved impact resistance
• Larger or faster print jobs where stable material feed is important

When it may not be suitable

This filament is not intended for applications that require high heat resistance above the specified Vicat and HDT values. For parts exposed to continuous temperatures above about 50–55 °C, consider alternative engineering materials with higher thermal performance. Additionally, while PLA+ improves toughness, it is not a direct substitute for high-performance engineering plastics in demanding mechanical or chemical environments.

How to use

Load the 1.75 mm filament into your FDM printer and set print temperatures and speeds according to your printer manufacturer’s guidance and the filament’s melting characteristics. Typical printing uses temperatures around the material’s melting point; tune retraction and flow settings to match the higher flow of PLA+ 2.0. Use a heated bed if required for adhesion and adjust cooling to balance surface finish and layer bonding. Store filament in a dry environment or filament dryer to prevent moisture absorption.

What to consider before purchase

• Verify your printer supports 1.75 mm filament and can be tuned for higher flow rates
• Assess required thermal performance against Vicat/HDT values if parts will face elevated temperatures
• Consider part function to determine whether PLA+ mechanical properties are sufficient
• Plan for dry storage to maintain filament quality

Usage recommendations

For consistent results, start with manufacturer-recommended temperature and speed settings, then fine-tune flow, retraction, and cooling. For large or fast prints, monitor first layers for adhesion and adjust bed temperature or adhesion aids as needed. Keep the filament dry and use moderate part cooling to optimize strength and surface finish.
