Filament PLA+ 2.0 (Olive) – Sunlu PLA+ 2.0 OG, 1.75 mm, for FDM 3D printers

Sunlu PLA+ 2.0 filament in Olive is a 1.75 mm PLA+ material for FDM 3D printers that balances ease of printing with enhanced durability. Compared with standard PLA, this version 2.0 offers increased flow for steadier extrusion, reduced warping, and a tolerance of ±0.02 mm to help maintain dimensional precision. It is suitable for users who need faster print speeds, reliable feeding, and finished parts with improved toughness.

Advantages

Sunlu PLA+ 2.0 combines the user-friendly behaviour of PLA with mechanical performance closer to Easy ABS, providing better crack resistance, higher tensile strength and improved impact resistance. The filament supports higher printing speeds while keeping surface quality and reduces the likelihood of nozzle clogging thanks to a more consistent melt flow. A low warping tendency and stable feed help achieve repeatable results across a range of models.

Suitable for

• Prototyping and concept models
• Functional parts that require improved toughness
• Decorative prints with consistent surface finish
• Faster production runs and workshop tasks

When it may not be suitable

This PLA+ is not intended for high-temperature structural applications; its Vicat softening temperature and HDT are around 54 °C, so parts exposed to sustained heat above this range may deform. For applications requiring very high thermal resistance or solvent resistance, other engineering-grade thermoplastics would be more appropriate.

How to use

Use standard PLA temperature settings in your slicer as a starting point and adjust according to your printer and nozzle. Ensure the filament spool is dry before printing; storing in a dry environment or using a filament dryer helps maintain print quality. Calibrate extrusion multiplier and retraction settings to match the improved flow characteristics, and verify bed adhesion methods suitable for PLA to minimise warping during cooling.

What to consider before purchase

• Confirm your printer supports 1.75 mm filament and can use PLA-based materials
• Check the expected operating temperature of final parts against the filament’s Vicat/HDT values
• Plan for proper filament storage to avoid moisture absorption

Usage recommendations

For best results, start with typical PLA print temperatures, fine-tune extrusion and retraction for the filament’s higher flow, and keep the filament dry. Use Sunlu PLA+ 2.0 for faster prints of functional prototypes and durable decorative parts while avoiding prolonged exposure to temperatures above ~54 °C.
