3D Printer Filament Sunlu PLA+ 2.0 Sunny Orange, PLA+ material, 1.75 mm

Sunlu PLA+ 2.0 Sunny Orange is a 1.75 mm PLA+ filament formulated for FDM/FFF 3D printing. The material version 2.0 improves flow and feed stability compared with standard PLA, helping to reduce extrusion issues and warping while supporting faster print speeds. It is intended for users who need reliable, durable prints with good surface finish and consistent dimensional results.

Advantages

Sunlu PLA+ 2.0 combines the user-friendly printing characteristics of PLA with enhanced toughness and crack resistance similar to Easy ABS. The filament provides smoother feeding due to improved flow, lower tendency to warp, and supports higher printing speeds without frequent nozzle clogs. These properties make it suitable for producing sturdier models and functional parts while maintaining an attractive surface quality.

Suitable for

• Prototyping and concept models
• Hobby and decorative prints
• Functional parts with moderate mechanical loads
• Educational projects and classroom use

When it may not be suitable

This PLA+ filament has a moderate heat resistance (Vicat ~54 °C, HDT ~53.8 °C), so it is not appropriate for applications exposed to sustained high temperatures or direct sunlight where parts could soften or deform. For parts that require high-temperature resistance or chemical resistance, alternative engineering materials should be considered.

Key specifications

• Material type: PLA+ (improved PLA formulation)
• Diameter: 1.75 mm ±0.02 mm
• Density: 1.21 g/cm³
• Vicat softening temperature: 54 °C
• Heat deflection temperature (HDT): 53.8 °C
• Melting temperature: 164 °C
• Melt flow rate: 7.8 g/10 min
• Tensile strength: 53.4 MPa
• Elongation at break: 20.3 %
• Flexural strength: 81.8 MPa
• Flexural modulus: 2740 MPa
• Impact strength (IZOD, notched): 19.8 kJ/m²

How to use

Load the 1.75 mm filament into any compatible FDM/FFF 3D printer. Typical printing settings for Sunlu PLA+ 2.0 are similar to standard PLA but may be adjusted to benefit from the improved flow: nozzle temperature near the material melting point (around 200–220 °C depending on your printer and nozzle), bed temperature 50–60 °C if a heated bed is used, and print speeds up to 300 mm/s where printer hardware and part geometry allow. Ensure proper filament drying and storage to avoid moisture-related print issues and verify first-layer adhesion before long prints.

What to consider before purchase

• Confirm your printer accepts 1.75 mm filament
• Check that required print temperatures are supported by your extruder and hotend
• Consider part exposure to heat—PLA+ has limited high-temperature resistance
• Plan for proper filament storage or use a dryer to prevent moisture absorption

Usage recommendations

For best results with Sunlu PLA+ 2.0 Sunny Orange, print with a stable extrusion setup, moderate cooling, and test a range of nozzle temperatures and speeds for your specific printer. Use a heated bed or adhesive surface for larger prints and store the filament in a dry environment to preserve print quality.
