Exact specifications as described

Measured the dimensions with calipers, and it is exactly 6x20mm. The resistance matches the expected values for the wattage. Highly recommended for DIY repairs.

Good quality, fast shipping

The build quality seems solid. I am using the 24V 40W version and it works great with my PLA and PETG prints. One star off because the wires were slightly stiff.

Reliable heating element

My old heater died after two years, and this replacement brought my printer back to life immediately. No issues with temperature fluctuations so far.

Great value for money

Bought three of these as spares for our community printers. They are durable and handle continuous operation well without overheating the surrounding components.

Perfect replacement for my Ender 3

This heating rod fits perfectly into my extruder block. It heats up quickly and maintains temperature very steadily. Installation was straightforward.

Works but instructions needed

The part itself works fine, but I wish there were some installation tips included. I had to watch a YouTube video to make sure I didn't damage the thermistor slot.

5 FAQ

Q: Does this come with thermal paste?

A: No, thermal paste is not included in the package. We recommend applying a small amount of high-temperature thermal paste during installation for optimal heat transfer.

Q: What is the difference between the 30W and 50W versions?

A: The main difference is the heating speed. The 50W version will reach target temperatures faster, which is useful for high-flow printing, while the 30W is sufficient for standard printing speeds.

Q: Is this compatible with the Creality CR-10 stock hotend?

A: Yes, this 6x20mm cartridge heater is fully compatible with the stock hotends found on most Creality CR-10 and Ender series printers.

Q: Can I use a 24V heater on a 12V power supply?

A: No, you must match the voltage. Using a 24V heater on a 12V supply will result in significantly reduced heating performance (approximately 1/4 of the rated power).

Q: How long is the warranty on this item?

A: This product comes with a standard 6-month manufacturer warranty covering defects in materials and workmanship under normal use.
