SUNLU vs Frucindra Filament Specs
Material Grade
SUNLU uses standard PLA, a reliable choice for general printing that balances ease of use with quality results. Frucindra offers PLA+, which typically provides improved strength and durability compared to standard PLA. The plus designation suggests better layer adhesion and reduced brittleness, making it suitable for functional parts that require more resilience. If you need standard, easy-to-print material, SUNLU is the straightforward option. For projects demanding slightly higher mechanical performance, Frucindra’s PLA+ variant offers a distinct material advantage.
Dimensional Accuracy
Precision in filament diameter is critical for consistent extrusion and avoiding clogs or under-extrusion. SUNLU guarantees a tight tolerance of +/- 0.02mm, ensuring the filament stays within a very narrow range of the 1.75mm standard. Frucindra specifies a tolerance of ±0.03mm. While both are well within acceptable limits for most FDM printers, SUNLU’s tighter specification means slightly less variance in diameter. This minor difference may result in smoother feeding and more consistent wall thicknesses for users who prioritize extreme precision in their dimensional output.
Color Options
SUNLU offers a wide variety of colors, including black, white, red, transparent, grey, wood, and green, allowing you to match specific project needs or aesthetic preferences. Frucindra focuses on a specialized glow-in-the-dark effect, offering green, blue, blue-green, and crystal rainbow colors that emit light after charging. If you need standard solid colors for everyday models, SUNLU provides more variety. For unique, eye-catching displays that glow in the dark, Frucindra delivers a specific visual feature that standard filaments cannot match.
Print Speed
SUNLU recommends a printing speed range of 50-100mm/s, allowing for relatively fast production of parts without sacrificing quality. This upper limit of 100mm/s is suitable for rapid prototyping or larger models where time is a factor. Frucindra does not list a specific recommended print speed in its published data. Without this specification, you may need to experiment to find the optimal speed for their PLA+ filament. SUNLU provides a clear, actionable guideline for achieving efficient print times right out of the box.
Packaging
Frucindra includes vacuum-sealed moisture-proof packaging with desiccant for each spool, effectively preventing moisture absorption during storage. This is crucial for PLA+ materials, which can degrade or bubble if exposed to humidity. SUNLU’s data does not mention vacuum sealing or included desiccant, though it emphasizes neat winding to prevent tangles. If you store filament for long periods or live in a humid environment, Frucindra’s packaging offers better protection against moisture damage, ensuring consistent print quality over time.
Which filament should you buy
Users needing reliable black prints
Choose SUNLU for standard black PLA projects. It offers tighter dimensional accuracy at +/- 0.02mm compared to the competitor. This precision helps prevent clogs and ensures smooth feeding. The 1KG spool supports speeds up to 100mm/s, making it a versatile choice for consistent, high-quality layer adhesion on most FDM printers.
Creators wanting glowing effects
Select Frucindra for unique, luminous prints. This PLA+ filament glows in the dark after charging with light. It includes four distinct colors totaling 1KG. The material provides stronger durability than standard PLA. While accuracy is +/- 0.03mm, the visual impact and vacuum-sealed packaging make it ideal for decorative or night-light projects.
Beginners prioritizing ease of use
SUNLU is ideal for new users due to its proven reliability. The 1.75mm diameter with +/- 0.02mm tolerance reduces tangles and jams. It works well with standard settings between 200-230°C. The neat winding process ensures smooth feeding. This simplicity allows beginners to focus on learning without troubleshooting material issues or complex print adjustments.
Those seeking durable multi-color sets
Pick Frucindra if you need variety and strength. The PLA+ grade offers improved toughness over standard PLA. You get four colors in one pack, perfect for multi-material designs. The vacuum packaging keeps filament dry and fresh. Although dimensional accuracy is slightly looser at +/- 0.03mm, the enhanced durability and unique glow effect justify the choice.
