Product: 0.4 mm 3D printer nozzle for 1.75 mm filament (approx. 0.16 in / 0.4 mm) Key benefits - Precise, reliable extrusion: 0.4 mm nozzle diameter (approx. 0.16 inch) provides a balanced combination of detail and print speed for most printing tasks. - High-temperature capability: designed to support high-temperature materials — up to 260°C with the integrated 100K thermistor version, and 300+°C when used with a compatible thermocouple (thermocouple not included). - Direct compatibility: made for extruders that use 1.75 mm filament, ensuring straightforward fitment with standard 1.75 mm 3D printers. What it does and why you need it - Delivers consistent filament flow and layer lines for dependable prints. - Enables printing of higher-temperature engineering materials when paired with the appropriate temperature sensor arrangement. - Offers a standard 0.4 mm orifice widely used for general-purpose printing, simplifying nozzle swaps and tuning. Important specifications - Nozzle diameter: 0.4 mm (approx. 0.16 inch) - Filament compatibility: 1.75 mm - Temperature: - Integrated thermistor option: supports melting of high-temperature materials up to 260°C with a 100K thermistor. - Thermocouple option: allows 300+°C operation when a thermocouple is installed (thermocouple not included). - Intended use: replacement or upgrade nozzle for 1.75 mm filament extruders and 1.75 mm 3D printers. Practical use scenarios - Printing high-temperature engineering filaments: use the integrated 100K thermistor variant to print materials that require up to 260°C nozzle temperatures. - Ultra-high-temperature applications: install a compatible thermocouple (sold separately) to enable 300+°C extrusion for specialty materials that demand extreme temperatures. - Everyday prototyping and models: use the 0.4 mm nozzle for balanced detail and speed on PLA, ABS, PETG and similar filaments on 1.75 mm setups. Notes and compatibility reminders - This nozzle is specified for 1.75 mm filament systems and standard 0.4 mm extrusion. - Thermocouple is not included; the 300+°C capability requires a compatible thermocouple installation. - The integrated thermistor option uses a 100K thermistor rated for operation up to 260°C. Choose this 0.4 mm nozzle for dependable, compatible extrusion with options to support higher-temperature printing when your workflow requires it.
