This allows for in-hotend color blending and material transitions without a separate toolchanger, while also boosting volumetric flow to ≥400 g\/h — significantly higher than most conventional single-filament hotends.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What filament types are compatible with the DualVelo AIR Lite hotend?\u003c\/h4\u003e\n\u003cp\u003eA: The DualVelo AIR Lite supports a wide range of FDM filaments including PLA, ABS, TPU, PETG, PC (polycarbonate), PA (nylon), and many other engineering-grade materials. Its all-metal construction and 400°C maximum temperature capability make it suitable for high-temperature filaments that require an all-metal hotend.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does the DualVelo AIR Lite require assembly?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, assembly is required. The kit includes all necessary components — hotend, extruder with motor, PT1000 sensor, heater cartridges, nozzles, and thermal grease. Extruder reference configuration values (rotation_distance: 23.24, gear_ratio: 30:10) are provided to help you dial in your slicer or firmware settings quickly.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What nozzle sizes are available for the DualVelo AIR Lite?\u003c\/h4\u003e\n\u003cp\u003eA: The DualVelo system supports brass nozzles in seven sizes: 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm, and 2.0 mm, giving you full control over the trade-off between print detail and extrusion speed. Nozzle-only replacement sets are available separately.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What size cooling fan should I use with the DualVelo heatbreak?\u003c\/h4\u003e\n\u003cp\u003eA: Mellow recommends mounting a cooling fan of at least 40 mm at the middle of the heatbreak. A larger fan delivers better airflow, keeps the thermal break zone cooler, and reduces the risk of heat creep or filament backflow during long, high-throughput print sessions.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
