Great value kit

Getting the heater block, thermistor, and thermocouple in one pack saved me time and money. Everything works as expected right out of the box.

Good quality, fast shipping

The parts feel sturdy and well-machined. Installation was straightforward. I deducted one star only because the instructions were a bit vague, but overall a great purchase.

Solid component

The machining on the aluminum is clean with no burrs. The threading for the nozzle is precise. It's a reliable part for any 3D printer enthusiast.

Perfect replacement for my Makerbot

This heater block fit perfectly into my existing setup. The aluminum conducts heat evenly, and the included thermistor is accurate. My prints have never been more consistent.

Excellent thermal stability

I upgraded to this block to handle higher temperature filaments like ABS and Nylon. It holds temperature very steadily with no fluctuations. Highly recommended for upgrades.

Fixed my heating issues

My old block was corroded and causing temperature drops. This new aluminum block solved the problem immediately. Prints are coming out smooth again.

5 FAQ

Q: Is this compatible with Ender 3 printers?

A: While primarily designed for Makerbot styles, it can be adapted for Ender 3 models with minor mounting adjustments due to the standard M6 thread.

Q: Does the package include screws for installation?

A: No, the package includes the heater block, thermistor, and thermocouple only. You will need to reuse your existing mounting screws.

Q: Can this handle PLA and PETG filaments?

A: Yes, this heater block supports temperatures well beyond what is required for PLA and PETG, making it suitable for a wide range of materials.

Q: What is the resistance value of the included thermistor?

A: The included thermistor is a standard NTC 100K type, which is compatible with most mainstream 3D printer controller boards.

Q: Is the heater cartridge pre-installed?

A: The heater cartridge is not pre-installed to prevent damage during shipping, but the block is drilled to accept standard 6mm cartridges easily.
