SUNLU vs Comgrow Filament Specs
Dimensional Accuracy
Both SUNLU and Comgrow PLA filaments claim a dimensional accuracy of +/- 0.02mm. This tight tolerance is critical for smooth feeding through your printer’s extruder. Consistent diameter prevents clogs and ensures uniform layer height. SUNLU achieves this with a self-developed neat winding device that reduces tangles. Comgrow uses a self-adaptive control system during manufacturing to maintain consistency. Since both brands specify the same +/- 0.02mm tolerance, you can expect similar feeding reliability from either spool. This spec directly impacts print quality and reduces the risk of jams during long prints.
Print Speed
SUNLU recommends a printing speed range of 50-100mm/s for optimal results. Their key specs list a max print speed of 100mm/s. Comgrow does not explicitly state a maximum print speed in the provided data. However, it notes that the filament has strong toughness and low shrinkage, which can support faster extrusion. Without a specific speed limit from Comgrow, SUNLU offers clearer guidance on high-speed performance. If you plan to push your printer to its limits, SUNLU’s stated 100mm/s target gives you a concrete benchmark for tuning your slicer settings.
Spool Dimensions
SUNLU provides detailed spool dimensions: 8.00 inches in diameter, 2.50 inches in width, and a 2.20-inch hub hole. These measurements ensure compatibility with most FDM 3D printer filament holders. Comgrow does not list specific spool dimensions in the provided data. SUNLU’s explicit sizing helps you verify fitment on your machine before buying. The 8-inch diameter is a standard size that fits most open-frame and enclosed printers. If spool compatibility is a concern for your specific printer model, SUNLU’s detailed specs reduce the risk of purchasing a spool that does not fit your feeder mechanism.
Temperature Settings
SUNLU recommends a nozzle temperature of 200-230°C and a bed temperature of 50-65°C. This wider range allows flexibility for different printer hotends and bed surfaces. Comgrow suggests a nozzle temperature of 210-220°C. It does not specify a bed temperature range in the provided data. SUNLU’s broader nozzle range accommodates various filament formulations and printer calibrations. Comgrow’s narrower range is typical for standard PLA but offers less guidance for edge cases. If your printer runs hotter or cooler than average, SUNLU’s recommendations provide a safer starting point for tuning.
Variety and Options
SUNLU offers 30 variations, including multiple sizes (1kg, 2kg, 3kg, 4kg, 5kg) and diverse colors like Black, White, Red, Transparent, Grey, Wood, and Green. Comgrow lists only 3 variations: 1KG PLA White, 1KG PLA Black, and a Filament Dryer. SUNLU provides significantly more color and size choices. If you need specific colors or bulk quantities, SUNLU has a broader selection. Comgrow’s limited options focus on basic white and black 1kg spools. For users who require specialized colors or larger spools for production, SUNLU’s variety is a clear advantage.
Which filament brand fits you best
Users needing specific black prints
SUNLU offers a dedicated black PLA option in 1kg spools. This color choice suits users requiring dark, opaque functional parts or aesthetic models. The filament maintains the standard 1.75mm diameter with +/- 0.02mm accuracy, ensuring reliable feeding. You get consistent layer adhesion and no clogs, making it a practical choice for black print projects.
Users needing specific white prints
Comgrow provides a white PLA variant that meets your color requirements. Like SUNLU, it features 1.75mm diameter with +/- 0.02mm tolerance for smooth extrusion. The vacuum-sealed packaging with desiccant protects the filament from moisture. This helps prevent bubbles and ensures high-precision prints, making it ideal for white functional or display models.
Printers prioritizing spool compatibility
SUNLU specifies its spool dimensions clearly: 8.00-inch diameter, 2.50-inch width, and a 2.20-inch hub hole. These measurements are designed to fit many common FDM 3D printers. If your printer has specific spool holder constraints, these exact physical dimensions help you verify compatibility before buying, reducing the risk of mechanical fit issues.
