Features: IntegratingTitan extruder and BP6 module, combining the advantages of light weight and strong stability, it provideshigh-quality 3D printer extrusion system for 3D printing enthusiasts. The heat dissipation block is equipped with a BP6 hot end, perfectly combined with theTitan wire feeding system, with a compact overall appearance and a strong sense of technology; The wirefeeding system decelerates 1:3 to improve wire feeding resolution. The distance from the extrusion wheel to the melt cavity is 25mm shorter than that of the V6 heat dissipation tube, effectively improving rigidity, making wire feeding more precise and flexible, and reducing printing defects. Aero radiator material: 6063 aluminum alloy surfaces treatment: sandblasted silver oxides. The radiator using highprecision imported CNCmachining centers, optimizing the assembly design of the throat, making it more convenient to install and replace Specially optimized for the heat dissipation problem of the throat, improving the heat dissipation efficiency of the throat and effectively preventing the occurrence of blockage Specifications: Feeding method: shortrange feeding Applicable consumables: 1.75mmPLA/ABS Nozzle aperture: default 0.4mm Aero radiator material: 6063 aluminum alloy Surfaces treatment: sandblasted silver oxides Size:Mixed Color:Red/White/Black/Silver Note: Please allow 1-3mm error due to manual measurement.Pls make sure you do not mind before you bid. The color may have different as the difference display,pls understand. Package includes: 1Set Aluminum Alloy Cooling Block
