PrimaCreator Bambu Lab A series Hotend H 0.4/1.75mm

Optimized Heat Management

The aluminum alloy heatsink provides excellent thermal conductivity, enabling rapid heat dissipation. This helps prevent clogging during continuous use and ensures that the filament melts consistently. Combined with the titanium heatbreak—which has a thin 0.15 mm wall and a smooth Ra0.3 inner surface—the system insulates heat effectively while keeping the extrusion path clear and reliable.

High-Efficiency Heating

The plated copper heatblock delivers superior heating performance. Its high thermal conductivity ensures fast and stable heating, perfectly suited for high-speed printing and demanding applications. This efficiency supports consistent filament flow, even under elevated temperature conditions.

Durable and Versatile Nozzles

The hotend is available with two nozzle types, each optimized for different applications. The hardened steel nozzle provides durability for abrasive materials such as carbon fiber, wood-filled, or glow-in-the-dark filaments. The plated copper nozzle, on the other hand, offers excellent resistance at high temperatures, making it ideal for engineering-grade filaments.

Stable & Lightweight Design

Its integrated and lightweight structure enhances stability during high-speed printing, reducing vibration and improving accuracy. At the same time, the design simplifies maintenance, making nozzle swaps and cleaning more efficient. This combination of stability and convenience makes the hotend suitable for both professional users and advanced hobbyists.
