A step limit has been added at the fitting point with the heating block, reducing the phenomenon of material leakage and detachment. 【Screw fixation】The connection between the heating block and the radiator is upgraded to two titanium alloy screws for fixation, avoiding the bending and breaking of the throat during high-speed printing. At the same time, titanium alloy has better insulation effect and increases stability.
