3D Printer Filament Sunlu PLA+ 2.0 (ceramic) — PLA+ polymer filament for FDM/FFF printers

Sunlu PLA+ 2.0 (ceramic) is a PLA+ polymer filament for FDM/FFF 3D printers that combines improved toughness and reliable feed behavior with the ease of printing typical for PLA. With a 1.75 mm diameter and ±0.02 mm tolerance, the filament reduces extrusion issues and warping while delivering smooth surfaces and consistent results for prototypes, decorative parts and functional models.

Advantages

Sunlu PLA+ 2.0 offers higher flow and greater durability than standard PLA, enabling faster printing and fewer nozzle clogs. The material has mechanical properties closer to easy ABS—improved tensile and flexural strength and higher impact resistance—while retaining PLA’s low-warp and user-friendly printing characteristics. Wide compatibility with most FDM printers and stable feeding make it suitable for both hobby and professional use.

Suitable for

• Rapid prototyping and concept models
• Decorative parts and display models with smooth surfaces
• Functional components that require improved durability
• Batch printing where higher speeds are needed (up to 300 mm/s)

When it may not be suitable

This filament is not intended for high-temperature applications where long-term exposure above its Vicat softening temperature (around 54 °C) or heat deflection temperature (~53.8 °C) would occur. For parts that must withstand sustained heat or outdoor UV/weather exposure, consider engineering-grade materials specifically designed for those conditions.

How to use

Start from standard PLA settings and adjust as needed: recommended extrusion temperature near the material’s melting point and tuned cooling to achieve the desired surface finish. Because Sunlu PLA+ 2.0 supports higher flow, ensure your printer’s extrusion multiplier and retraction settings are calibrated to prevent over-extrusion. Use a dry filament environment or filament dryer to maintain consistent feeding and avoid moisture-related print defects.

What to consider before purchase

• Intended operating temperature of final parts (avoid sustained loads above ~54 °C)
• Printer compatibility with 1.75 mm filament and the printer’s maximum recommended print speed
• Need for post-processing (sanding, painting) depending on surface finish requirements

Usage recommendations

For reliable results, print Sunlu PLA+ 2.0 (ceramic) with a well-calibrated extrusion system, moderate cooling for high-detail surfaces, and consider speeds up to 300 mm/s only after confirming stable material feed and dimensional accuracy on test parts.
