Features: brand new and high quality brand new and high quality Integrating the Titan extruder and BP6 module, combining the advantages of light weight and strong stability, provides a high-quality 3D printer extrusion system for the majority of 3D printing enthusiasts. The heat sink is equipped with BP6 hot end, which is perfectly integrated with the Titan wire feeding system. The overall appearance is compact and the sense of technology is full. The wire feeding system is reduced by 1:3 to improve the wire feeding resolution. The distance from the extrusion wheel to the melting cavity is 25mm shorter than that of the V6 heat pipe. The rigidity is effectively improved, the wire feeding is more precise and flexible, and printing defects are reduced. Surface treatment: sandblasted and oxidized silver, the radiator is processed by a high-precision imported CNC machining center at one for time. The radiator is specially optimized and differs from similar products in that the assembly design of the throat is optimized to make it easier to install and replace. In addition, it is specially optimized for the heat dissipation problem of the throat pipe, which improves the heat dissipation efficiency of the throat pipe and can effectively prevent the occurrence of blockage. Aero radiator characteristic material: 6063 aluminum alloy. Specifications: Material: 6063 Aluminum alloy Feeding method: remote feeding, short-range feeding Applicable consumables: 1.75mm PLA/ABS Nozzle aperture: 0.4mm by default Package Includes: 1Set x Aero Heat Sink note: Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.
