PLA+ Filament Sunlu 2.0 (magenta) — 1.75 mm, PLA+ material for FDM 3D printers

Sunlu PLA+ 2.0 filament in magenta is a 1.75 mm PLA+ material formulated for FDM 3D printers. It provides improved flowability and mechanical properties compared with standard PLA, enabling reliable extrusion, reduced warping, and smoother high-speed printing. The filament is intended for users who need consistent feed and durable prints for both prototyping and functional parts.

Advantages

Sunlu PLA+ 2.0 offers up to 1.5× greater flowability than standard PLA, a tolerance of ±0.02 mm on 1.75 mm diameter for precise extrusion, and enhanced toughness comparable to Easy ABS. The material combines easy printing characteristics of PLA with increased crack resistance and lower risk of nozzle clogging, supporting printing speeds up to 300 mm/s while maintaining stable layer adhesion and reduced deformation.

Suitable for

• Rapid prototyping and iterative design
• Decorative models and visual mock-ups
• Functional parts requiring increased toughness
• Workshops and small-batch production with higher print speeds

Когда может не подойти

PLA+ имеет более высокую теплостойкость, чем стандартный PLA, но температура размягчения и теплового сопротивления остаются ниже значений материалов, таких как ABS или нейлон. Поэтому этот филамент может быть неприемлем для деталей, которые постоянно экспонируются при температурах выше примерно 50–55 °C или испытывают интенсивное механическое истирание в агрессивных условиях.

How to use

Load the 1.75 mm filament into any compatible FDM extruder and set printing parameters according to your printer and model complexity. Start with a nozzle temperature near the filament melting point and adjust within the printer-recommended range to optimise extrusion and layer adhesion. Use a well-leveled bed and appropriate adhesion method for the build surface; drying the filament before printing can help maintain consistent feed and prevent moisture-induced defects. When printing at higher speeds, verify cooling and retraction settings to avoid stringing while preserving good layer bonding.

What to consider before purchase

• Intended operating temperature of the finished part (Vicat ~54 °C)
• Compatibility with your FDM 3D printer and nozzle diameter
• Storage and drying needs to prevent moisture absorption
• Desired balance between print speed and surface finish

Usage recommendations

For best results with Sunlu PLA+ 2.0 (magenta), use a 1.75 mm nozzle, pre-dry filament if stored in humid conditions, start with conservative temperature and speed settings then tune upward, and avoid prolonged exposure of printed parts to temperatures above the Vicat softening point.
