0.4mm 3D Printer Hotend Assembly Compatible with FLSUN Super Racer (SR) 3D Printer, High-Flow Volcano Nozzle

Key features

• Precisely engineered to be fully compatible with the FLSUN Super Racer (SR) Delta 3D printer. This aftermarket hotend assembly serves as a direct replacement for the stock print head. It comes pre-assembled and pre-wired with the heating rod and thermistor, allowing for a seamless, hassle-free installation within minutes to minimize your printer's downtime
• Featuring an upgraded bi-metal heatbreak constructed from copper and titanium alloy. Titanium blocks heat from creeping upward into the cold end, while copper dissipates heat rapidly. This advanced thermal isolation prevents filament from softening prematurely, effectively eliminating clogs during high-speed printing or long-duration 3D prints
• Equipped with an upgraded high-temperature thermistor cartridge and a premium heater block, this hotend allows your FLSUN SR to break past limit up to 300°C
• Includes a volcano-style high-flow brass nozzle with an extended melting zone. This layout provides consistent volumetric flow rate even when your Super Racer is sprinting at speeds over 150mm/s. Ensuring smooth extrusion and flawless surface finish
• Every single FLSUN SR compatible hotend undergoes rigorous manual inspection for thread tolerance and electrical conductivity prior to shipment. Carefully packed in high-density protective foam to guarantee safe transit. As dedicated 3D printing enthusiasts, we offer 24/7 technical customer support to assist with your upgrade setup
