Good value, works as expected

I bought the 24V version for my Voron setup. Installation was straightforward, and it reaches target temps without issues. Deducting one star only because the wires were slightly stiff.

Solid build quality

The stainless steel casing feels robust. I tested it with a multimeter before installation, and resistance values were exactly within spec for a 50W unit.

Best budget heater cartridge

Compared to OEM parts that cost three times as much, this KINGROON heater performs just as well. My prints have no temperature fluctuations.

Reliable and durable

I've been running this heater for over 200 hours now with ABS filament. No degradation in performance yet. Highly recommend for anyone needing a spare.

5 FAQ

Q: What is the exact diameter of the cartridge?

A: The cartridge has a standard diameter of 6mm and a length of 20mm, making it compatible with most common hotend blocks designed for 6mm heaters.

Q: Does it come with thermal paste?

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

Q: Can I use this for printing PLA?

A: Absolutely. This heater can easily reach and maintain the temperatures required for PLA (typically 190-220°C) as well as higher temperature materials like ABS or PETG.

Q: Is this compatible with a 12V power supply?

A: Yes, we offer both 12V and 24V versions. Please ensure you select the correct voltage option that matches your printer's power supply before ordering.

Q: How long are the lead wires?

A: The lead wires are approximately 100cm (1 meter) long, which provides enough slack for most standard 3D printer wiring setups.
