High power density

For such a small size, 70W is impressive. It handles ABS and PETG printing temperatures with ease. A must-have spare part.

Perfect replacement for my Ender 3

This heating cartridge fits perfectly into my hotend block. It heats up quickly and maintains temperature very consistently. Great value for a 70W unit.

5 FAQ

Q: What is the exact length of the wires included?

A: The wires are approximately 1 meter (1000mm) long, which is sufficient for most standard 3D printer wiring harnesses.

Q: Does it come with thermal paste?

A: No, this package includes only the heating cartridge. We recommend applying high-temperature thermal paste during installation for better heat conductivity.

Q: How do I verify if I need 12V or 24V?

A: Check your printer's power supply unit (PSU) label or your mainboard documentation. Using the wrong voltage can damage the heater or result in insufficient heating.

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

A: Yes, this cartridge is available in both 12V and 24V versions. Please ensure you select the 12V option at checkout for compatibility with your RAMPS board.

Q: Can I use this for melting plastic in a non-printer application?

A: While it is designed for 3D printers, it can be used for other DIY heating applications provided the voltage and temperature requirements match your project specifications.
