0.4mm FlowTech CHT High Flow CM2 Micro Swiss Nozzle

The 0.4mm FlowTech CHT High Flow CM2 Nozzle from Micro Swiss is the ideal choice when you demand both the highest precision and maximum flow capacity in 3D printing. Thanks to the innovative CHT technology (Cold Heat Transfer), the filament is efficiently heated through a segmented bore, enabling a significantly higher melt rate. This high-flow nozzle allows you to print at increased speeds without sacrificing print quality. Its robust construction combines a heat-resistant copper-chromium-zirconium alloy with a nickel coating that protects against corrosion and abrasion. The nozzle tip is made of hardened high-speed steel M2 and is coated with an anti-stick nano-coating, allowing abrasive filament to be processed effortlessly. You can even change the nozzle when cold—no heating required. Some components of this high-quality system are sourced from Bondtech, another leading manufacturer in the field of professional 3D printing technology. This system is especially useful for makers, professionals, and industrial users who regularly use different filaments or frequently need to change the nozzle type. The heat treatment to 68 HRC also ensures long-lasting wear resistance. The nozzle is compatible with the FlowTech Hotend from Micro Swiss. Overall, the FlowTech CHT High Flow Nozzle offers you an optimal mix of performance, user-friendliness, and durability—for the best results in any project.

Features:

• Increased melt rate thanks to CHT technology: The segmented bore inside the nozzle enlarges the surface area of the heating channel, significantly enhancing heat transfer.
• High-quality nozzle body: Made from a copper-chromium-zirconium alloy, the nozzle withstands extremely high temperatures without losing its strength.
• Nickel coating protection: The electroless nickel coating provides optimal protection against corrosion and mechanical wear.
• Anti-stick surface: The WS2 nano-coating reduces friction to a minimum (coefficient of friction only 0.035), ensuring the filament flows particularly evenly.
• Durable nozzle tip: The insert made of hardened M2 high-speed steel is extremely resistant to abrasive filament.
• Cold nozzle change: The nozzle can be safely changed when cold, making handling easier and reducing the risk of injury.
• High hardness for long service life: Heat-treated to 68 HRC—ideal for demanding applications.
• Component quality from Bondtech: Selected components are sourced from Bondtech and guarantee the highest mechanical precision and reliability.
