Micro Swiss Microswiss FlowTech™ Hotend for Bambu Lab P1P/P1S – Brass Plated CHT – High Flow

The FlowTech™ CHT High Flow Nozzle is the result of a collaboration between Micro Swiss and Bondtech, engineered for significantly higher filament flow while maintaining print quality. It features advanced CHT technology and TwinClad® XT plating for smoother extrusion, improved layer adhesion, and cleaner prints—all compatible with the full FlowTech hotend range. Key Features

• Proprietary CHT design enables up to 50 mm³/s volumetric flow rate
• TwinClad® XT brass plating delivers low-friction, wear-resistant performance
• Multi-chamber melting zone ensures uniform layer deposition
• Compatible with all FlowTech hotends; available in .4, .6, .8, and 1.0 mm sizes
• Strong and reliable construction using high-temp alloy and hardened steel
• Designed and tested for clean prints with excellent part strength

High-Flow Performance Powered by CHT Technology

The nozzle integrates Bondtech’s proprietary CHT (Core Heating Technology), which splits filament into multiple internal chambers as it enters the melt zone. This innovation enables a maximum volumetric flow of up to 50 mm³ per second, allowing for faster printing without sacrificing layer definition. The multi-chamber approach not only boosts throughput but also enhances layer adhesion, resulting in smoother, more uniform prints.

Durable Engineering with TwinClad® XT Plating

Built from precision-machined brass, the nozzle is coated with Micro‑Swiss’s TwinClad® XT—a non-stick, wear-resistant composite plating. This finish reduces friction, prevents filament buildup, and promotes effortless extrusion, keeping surfaces clean and print runs seamless.

Structural Integrity and Material Excellence

Available in multiple orifice sizes (0.4, 0.6, 0.8, and 1.0 mm), the nozzle construction combines a heat-resistant copper-chromium-zirconium alloy core with an electroless nickel plating for corrosion resistance and heat endurance. For further durability, select variants (CM2™) feature a hardened M2 high-speed steel tip with a WS2 nano-coating, reaching 68 HRC hardness and ensuring minimal friction (coefficient ~0.035).

Universal FlowTech Compatibility

Engineered for seamless integration, the FlowTech™ CHT High Flow Nozzle fits all FlowTech hotend models. Whether you're upgrading your setup or changing print jobs, installation is direct and hassle-free.

Clean and Robust Printing Results

The combined effects of enhanced flow, plated performance, and multi-chamber design translate into reduced gaps, stronger interlayer fusion, and cleaner surfaces. You get consistently high-quality prints with efficiency and confidence—ideal for applications where both speed and precision matter.
