▉Name:
CHCB-OTC HOTEND KIT
The CHCB-OTC hot end is a hot end module that is a direct replacement for the stock hot end on the Creality K1C printer.
▉Description:
CHCB-OTC hotend is a hot end component, it can directly replace the original hot end on Creality K1C printer.
It made of better material, a higher flow rate and an easier maintenance design.
▉Highlight:
1.Planar contacts heating element have a more certain contact than ceramic heating ring contacts.
2.Higher power heating element for shorter warm-up time. More heating power is available when encountering high temperature ranges and high flow conditions.
3.compared to the original one OTC hotend heating elements and thermistors are easy to maintain and replace
4.The material choice of thin-walled stainless steel tubes and titanium screws for the connection structure minimizes the conduction of heat from the heating block to the heatsink.
5.It is compatible with the MK8 series of nozzles, which are already available on the market with various functions. (such ashardened steel, diamond, tungsten carbide, or high-flow series, etc.)，it reducing the nozzle costs in life-cycle.
6.Drop-in replacement for the hotend of the Creality K1C. As long as the nozzles are assembled and replaced correctly you have no chance of experiencing leakage issues.

▉Test Report:
Test introduction:
Compare the difference between the original hotend and OThotend printouts of the K1 printer
Test conditions:
printer:Creality K1
Filament:Creality hyper PLA
G-code: 600MM/S DEMO provide by Creality K1
Test Result:
As shown in the figure, after replacing the K1 printer with an OT hotend, the finished product printed at 600MM/S with the same Gcode file, the same filament, and the same nozzle is just as good, and the surface looks basically the same. But when we apply the same destructive force on the same place, the original hotend prints have layer separation, while the OT-hotend prints only show stress whitening. This indicat that the OT hotend has a higher flow rate in which the filament is more fully melted.
