All-metal hotend with resistance to high temperatures up to 500 ℃.
Excellent thermal insulation.
Reinforced rigid support structure.
The integrated rigid frame design allows for easier nozzle replacement without needing to hold the heat block.
Inner surface roughness of the nozzle and heat block is 0.4, enabling smoother filament movement and resulting in higher print accuracy.
The ST and HF versions share the same overall dimensions.
