3D printing filament eSun PLA+ PLA+175CW1, Polylactic acid plus (PLA+), 1 kg, print speed 100 mm/s

eSun PLA+ PLA+175CW1 is a 1 kg spool of modified polylactic acid designed for FDM/FFF 3D printers. This PLA+ formulation keeps the ease of printing typical for PLA while improving toughness and layer adhesion. The filament delivers a smooth surface finish, good rigidity and balanced strength, with an impact strength of 9 kJ/m² and a recommended print speed up to 100 mm/s. As a bio-based, environment-friendly material it is suitable for conceptual models, rapid prototyping and functional parts that require greater durability than standard PLA.

Advantages

This PLA+ filament is easy to print and reduces common printing issues while providing better toughness and stronger interlayer bonding compared with standard PLA. The material yields a smooth surface finish and maintains a good balance between stiffness and impact resistance, making it suitable for parts that must withstand handling and light mechanical loads. The filament is derived from a bio-based polymer and has FDA approval, which supports safer handling and broader application possibilities.

Suitable for

• Conceptual models and design prototypes
• Hobbyist parts and decorative objects with improved durability
• Functional models and fixtures requiring enhanced impact resistance
• Rapid prototyping with moderate mechanical demands

Key specifications

• Material: Polylactic acid plus (PLA+)
• Spool weight: 1 kg
• Recommended print speed: up to 100 mm/s
• Impact strength: approximately 9 kJ/m²
• Surface finish: smooth
• Printability: easy to print, improved layer adhesion

How to use

Load the filament onto a compatible FDM/FFF 3D printer and set standard PLA printing temperatures recommended for your machine, then adjust settings as needed for this PLA+ grade. Use typical nozzle diameters and ensure the print bed is level. Start with conservative speeds and test prints: although the filament supports speeds up to 100 mm/s, print quality may vary by printer and geometry. Allow printed parts to cool sufficiently before handling to ensure dimensional stability and optimal layer bonding.

Usage recommendations

For best results, print on a clean, properly leveled bed and use a brim or raft for small bases. Use a well-calibrated extrusion multiplier and moderate cooling to balance surface quality and interlayer adhesion. Store the filament in a dry environment or sealed container with desiccant to preserve printing performance.
