Key benefits - Precise, consistent extrusion: 0.4 mm opening and a smooth, burr-free inner wall deliver accurate, even filament flow for cleaner layers and finer detail. - Fewer clogs and under-extrusion: smooth internal surface and robust construction reduce filament hang-ups and missed extrusion during long prints. - Durable and corrosion-resistant: brass construction with high hardness and toughness offers strong wear resistance for longer nozzle life. - Suitable for high-temperature use: built for hotend applications where higher extrusion temperatures are required. What this nozzle does for you - Improves print reliability by minimizing blockages and material feed interruptions. - Produces smoother surface finish and more accurate dimensions thanks to the polished internal bore. - Withstands repeated use and abrasive filaments better than lower-quality nozzles, reducing downtime and replacement frequency. Key features - Material: Brass — high hardness and high toughness for durability. - Size: 0.4 mm nozzle diameter for balanced detail and print speed. - Internal finish: Smooth, burr-free inner wall for consistent flow. - Performance: Low thermal conductivity (as specified), corrosion-resistant, high abrasion resistance. - Application: Designed as an extruder / hotend nozzle for 3D printers; robust construction for high-temperature printing. Practical use scenarios 1) High-temperature filament printing — Use when printing ABS, PETG, or other higher-temperature materials where nozzle durability and hotend stability are important. 2) Long, continuous prints — Ideal for lengthy or production runs where clog resistance and consistent extrusion reduce failed prints. 3) Fine-detail prototypes and functional parts — The 0.4 mm orifice and smooth bore help produce cleaner details and reliable dimensional accuracy for small mechanical parts or visual models.
