About this item

  • High-Speed Printing: The H2D High Flow Hot End (HF) has a maximum volumetric flow rate increased to 65mm³/s compared to the Standard Flow Hot End (SF). This can significantly increase the printing speed. For example, the printing speed of PLA materials is notably enhanced, saving up to 30% of the printing time and greatly improving printing efficiency
  • High - quality Material: The print head uses all-metal titanium alloy throat tube with an inner wall roughness of only Ra 0.4. It has high hardness and anti - clogging properties. The 0.25mm wall thickness reduces clogging and improves printing quality. It can also withstand a high temperature of 350°C
  • Precise printing: high-speed and high-precision printing, clear and sharp details. After 120% ultra-high-speed comparison test, the H2D print head showed excellent printing quality
  • Convenient Replacement: Features a 30-second quick release design. With a unique heating component design, there is no need to connect electronic components. Just unlock to quickly detach the heating hotend.
  • Compatible 3d printer models: For Bambu Lab H2D combo/AMS 2pro/A1/A1 Mini. After testing, installing a high flow hot end on the A1/A1 Mini does not improve flow performance

The model on the left is the official .4 h2d high-flow hot end print, and the one on the right is SAHVAIM. With the same parameter settings, the accuracy and detail quality of the printed model will not decrease at all.
