Microswiss FlowTech™ Hotend for Bambu Lab X1/X1C - DiamondBack - Diamond Tip - Standard Flow

The FlowTech Hotend with DiamondBack Nozzle is a high-performance upgrade for the Bambu Lab X1 and X1 Carbon (X1C) printers. Built for extreme durability and smooth extrusion, this hotend combines Micro Swiss' FlowTech architecture with a true diamond tip nozzle - delivering unmatched durability, thermal stability, and ease of use in a plug-and-play format.

Important features

• Compatible with Bambu Lab X1 & X1 Carbon (X1C)
• DiamondBack nozzle with genuine polycrystalline diamond tip
• Bimetal heating block with excellent thermal insulation
• Cold-changeable nozzle - no tools or hot tightening required
• Ideal for abrasive filaments with standard flow performance
• No changes to firmware, hardware or slicer are required

Engineered for ultimate durability

At the heart of this hotend is a DiamondBack nozzle with a true polycrystalline diamond tip. Diamond is the hardest material known and provides unmatched wear resistance - perfect for printing abrasive filaments like carbon fiber, luminescent or metal-filled materials. The brass body ensures excellent thermal conductivity, while the diamond tip maintains dimensional accuracy over thousands of hours of printing.

FlowTech architecture with bimetal thermal control

The hotend features a bimetal thermal switch that combines a copper outer shell and a stainless steel core. This sharp thermal transition prevents heat creep and promotes reliable filament flow. Combined with the internal FlowTech geometry, it provides smooth extrusion with minimal clogging or pressure fluctuations.

Plug-and-Print compatibility

This hotend is a direct replacement for the standard unit in the Bambu Lab X1 and X1C printers. It requires no firmware changes, electrical wiring, or adjustments to the slicer. All AMS and printer features remain fully supported.

Cold nozzle changes, minimal downtime

Micro Swiss' tool-free nozzle replacement system makes maintenance quick, safe and simple. Change nozzles at room temperature without tools or hot clamping - saving time and reducing the risk of damage during servicing.
