Great spare part to keep on hand

Bought two of these as spares. They are compact and powerful. Installation was straightforward, and the printer is back up and running.

Reliable high-power heater

I needed a 70W heater for a custom high-flow setup, and this delivers. No issues with overheating or inconsistent readings after a week of heavy printing.

Works well for the price

Does the job nicely. The stainless steel sheath looks durable. Just make sure your power supply can handle the 70W draw continuously.

Good quality, fast shipping

The build quality seems solid. I installed it on a 24V system and it works as expected. Only giving 4 stars because the wires were slightly shorter than I hoped.

Perfect replacement for my Ender 3

This heating rod fits perfectly into the hotend block. It heats up quickly and maintains temperature very steadily. Great value for a DIY part.

5 FAQ

Q: What is the exact length of the heated section?

A: The total dimensions are 6mm in diameter and 20mm in length. The entire rod is the heated section as it is a cartridge style heater.

Q: How long is the wire lead?

A: The wire leads are approximately 1 meter long, which provides enough slack for most standard 3D printer wiring harnesses.

Q: Does it come with thermal paste?

A: No, the package includes only the heating rod. We recommend applying high-temperature thermal paste during installation for optimal heat transfer.

Q: Is this compatible with a 12V RAMPS board?

A: Yes, this heating rod supports both 12V and 24V inputs. Just ensure your firmware and power supply are configured correctly for 12V operation.

Q: Can I use this for melting plastics other than PLA?

A: Absolutely. With a max temperature capability of around 400°C, it is suitable for ABS, PETG, Nylon, and other common 3D printing filaments.
