BIGTREETECH 3D Printer Part 2 in 1 Out Hotend Multi Color Dual Bowden Extruder Full Kit with Silicone Sock for Titan MK8 Bulldog Extruders (24V Black Color)

Product Advantages
1,Select high-quality Aluminum alloy 6063 material,and use refined sandblasting oxidation treatment of product shell to improve the surface texture.
The heat dissipation efficiency is increased to 40% compared with the existing similar products which can effectively reduce and avoid the occurrence of the throat plug.
The weight of the Nozzle is at least 20-30% lighter than that of the same type Of the products and the printing accuracy and printing quality can be effectively improved.
The new design can ensure that the size change of the total height of the products is less than 0.5-1.0mm, which is beneficial to mass production.
We adopt double top wire fixing to effectively reduce the risk of pipe loosening.
It is made by using the CNC machining center imported from Germany at once time,which can effectively reduce the cumulative tolerance of the product and make the product more stable.
With 0.5 square wire high-temperature version heating rod and PT100 high temperature version thermistor, the Maximum heating temperature can reach 350 degrees, and the Maximum temperature measurement of the terminable can also reach 350 degrees.
