Sunlu High-Speed ABS Filament (Black) 1.75mm 1kg

For high-speed 3D printing, many ABS filaments fail to keep up, leading to clogs, warping, and brittle parts. The Sunlu High-Speed ABS Filament in black is engineered specifically for fast FDM printers, delivering consistent extrusion at speeds up to 300 mm/s while maintaining strong, durable prints. With a precise 1.75 mm diameter and vacuum-sealed packaging, this spool offers reliable performance for both hobbyists and professional makers.

Who is it for

This filament suits users with FDM 3D printers capable of high-speed printing, such as those with a direct-drive extruder or a well-tuned Bowden setup. It is also an excellent choice for functional prototypes, jigs, enclosures, and automotive or electronic components that need heat resistance and impact strength. Whether you run a print farm or an occasional desktop printer, the Sunlu High-Speed ABS delivers the stability you need for fast production.

Main features

• High-speed formulation: optimized for print speeds of 50–300 mm/s, reducing production time without sacrificing quality.
• Tight diameter tolerance: ±0.02 mm ensures smooth feeding and consistent layer deposition.
• Low shrinkage and excellent layer adhesion: minimizes warping and delamination for strong, accurate models.
• Heat-resistant: with a heat deflection temperature of ≥80 °C, parts withstand moderately warm environments.
• Vacuum-sealed with desiccant: factory-dried to prevent moisture absorption and extrusion defects.
• Precise spool dimensions: 200 mm spool diameter, 65 mm width, and 55 mm hub, compatible with most spool holders.

Tips

For best results, use an enclosed printer chamber to maintain a stable temperature and reduce warping. Ensure your bed is level and use a heated bed within 80–100 °C; consider an adhesive or ABS slurry for large prints. Store the filament in a dry box after opening, as ABS can absorb moisture. Always dry the filament if it has been exposed to humidity for an extended period.
