SUNLU vs FLASHFORGE Filament Specs
Print Speed
SUNLU recommends a maximum print speed of 100mm/s for its PLA filament. This setting is suitable for standard FDM printers and ensures reliable layer adhesion for beginners and experienced users alike. The filament is wound neatly to prevent tangles during these moderate speeds. In contrast, FLASHFORGE offers a High Speed PLA filament capable of reaching up to 500mm/s. This five-fold increase allows for significantly faster production of various applications. The filament features fast melting and even flow to maintain quality at these elevated velocities. If you prioritize rapid prototyping or large batch production, the FLASHFORGE option provides a clear advantage in throughput.
Dimensional Accuracy
Both brands claim identical dimensional accuracy for their 1.75mm PLA filaments. SUNLU specifies a tolerance of +/- 0.02mm, which ensures wide compatibility with almost all 1.75mm FDM 3D printers. This precision helps avoid clogs and bubbles during printing. FLASHFORGE also lists a tolerance of +/- 0.02 mm with a 99% probability. They achieve this consistency through CCD diameter measurement and adaptive control systems. This rigorous monitoring ensures smooth extrusion and clean, precise prints for both brands. Since the stated accuracy is the same, neither product holds a technical edge in filament diameter consistency based on the provided specifications.
Material Type
Both products are made from Polylactic Acid, commonly known as PLA. This material is a popular choice for 3D printing enthusiasts due to its reliability and versatility. SUNLU describes its PLA as easy to use, with excellent layer adhesion for high-quality results. FLASHFORGE also utilizes PLA, highlighting its robust nature and excellent bed adhesion. The FLASHFORGE filament is noted for stability without requiring pre-drying, which is unusual for many PLA types. Both filaments are compatible with standard FDM printing processes. Since both use the same base material class, they share fundamental properties like ease of use and low warping, resulting in a tie for material composition.
Spool Design
SUNLU provides detailed specifications for its spool dimensions. The spool measures 8.00 inches in diameter, 2.50 inches in width, and has a hub hole diameter of 2.20 inches. These dimensions are designed to fit a wide variety of FDM 3D printers. The filament is wound using a self-developed device to ensure a 100% neat rate, reducing jam risks. FLASHFORGE does not list specific spool dimensions in the provided data. While the net weight is 1kg for both, the physical spool size is a critical factor for printer compatibility. SUNLU offers more transparency regarding how its spool fits your machine, giving it the edge here.
Recommended Settings
SUNLU provides explicit printing parameters to help you achieve the best results. You should set the nozzle temperature between 200-230°C and the bed temperature between 50-65°C. The recommended printing speed is 50-100mm/s. These settings are tailored to their standard PLA formulation. FLASHFORGE does not list specific temperature or bed settings in the provided data. Instead, it emphasizes that its filament achieves excellent prints without pre-drying or complex parameter adjustments. While this suggests plug-and-play convenience, SUNLU gives you precise control over your printer settings. If you prefer defined parameters, SUNLU is the better choice.
Choose Your Filament By Speed
Standard printer users seeking reliability
If your printer runs at standard speeds, this SUNLU filament is the better choice. It supports up to 100mm/s with tight dimensional accuracy of +/- 0.02mm. The neat winding reduces tangles, ensuring smooth extrusion. You get consistent layer adhesion without needing complex parameter adjustments or pre-drying, making it ideal for dependable, everyday prints.
High-speed printer owners
This FLASHFORGE filament is designed for machines capable of fast printing. It supports speeds up to 500mm/s, allowing you to accelerate production significantly. The material features fast melting and even flow, which maintains quality at high velocities. You also benefit from excellent bed adhesion and stability, ensuring robust prints even when pushing your printer's limits.
Users wanting color-changing effects
FLASHFORGE offers unique options like Burnt Titanium, which reacts to light intensity. This color-changing material hides layer lines perfectly for stunning visual effects. While SUNLU focuses on standard black PLA, FLASHFORGE provides specialized finishes. If you want prints that shift appearance under different lighting, this high-speed filament gives you creative flexibility standard PLA cannot match.
